After more than 40 years practicing in corporate finance and merger and acquisition matters, primarily with large law firms and for large companies, Steve joined Brennan, Manna & Diamond as managing partner of its Scottsdale office. His objective is to offer the value imbedded in the experience, skills, contacts, and relationships developed representing both large institutional and entrepreneurial clients with the personal attention, agility, and flexibility of a boutique. 

Steve has prepared both private offering memoranda and registration statements in connection with private and public offerings of securities and has represented offerors and both individual and institutional investors in connection with transactions exempt from the registration requirements of federal and state securities laws. He has also conducted investigations for committees of independent corporate directors, and successfully resolved enforcement inquiries and investigations by the Securities and Exchange Commission (the SEC). 

In addition to his conventional corporate, transactional and corporate finance practice, Steve has been involved in more than $2 billion of cannabis industry merger and acquisition and debt and equity finance transactions, many with multi-state and/or international components. Clients have primarily been publicly traded corporate and private acquirers, private equity firms, high net worth private investors, family offices, and underwriters, and have also included owner/operators. 

For more than 12 years he acted as a business consultant and investment banker working primarily with privately owned small and middle market companies in connection with strategic and business planning, capital formation, and the sale of businesses and assets. 

Working with both public and private entities, his legal experience has focused on general business/ corporate and securities law, mergers and acquisitions and corporate and real estate finance, as well as banking law and regulation, lender and borrower representations in negotiating and documenting credit transactions and problem asset resolutions. He has both served as special counsel to federal and state bank regulatory authorities, nationally and regionally, and has negotiated with them on behalf of financial institutions in connection with the resolution of regulatory orders and proceedings. As both in-house and outside general or special counsel for financial institutions, he has developed and executed strategies for and coordinated multi-jurisdictional programs and systems for asset dispositions and litigations.



Since 2015, Steve has been representing clients in the cannabis business, focusing on Arizona and multi- state acquisition and financing transactions, significant commercial arrangements, and governance and regulatory matters. Steve has represented public and private company acquirers, institutional and high net worth equity and debt funders, as well as businesses seeking capital from those and other sources. He has also represented both operators and providers in connection with various joint venture, licensing, production and similar arrangements, ancillary businesses serving the cannabis industry, and sellers of substantial ownership interests in those businesses. 

Steve’s experience in the cannabis industry and his banking and bank regulatory knowledge offers a combination of capabilities that places him at the rapidly approaching intersection of those industries, putting him in a position to guide commercial banks, financial intermediaries and industry customers as they navigate this new frontier. Among numerous national speaking engagements, Steve organized and moderated a webinar in September 2021 on bank lending to the cannabis industry that was co-sponsored by the State Bankers Associations of Arizona, Colorado, Ohio, and Utah. 

Steve has been a speaker/panelist at multiple investor conferences presented by Kahner Global, Arcview, and Green Table in venues including Las Vegas, Los Angeles, New York, Ft. Lauderdale, and Toronto, and will be a speaker at the Benzinga Cannabis Capital Conference in April 2023, and at the PBC Conference 2023.

General Business, Securities, Merger & Acquisition and Corporate and Real Estate Finance

Steve’s practice included the representation of: 

  • Issuers, underwriters and selling shareholders in connection with federal and state requirements with initial, secondary and/or follow-on public offerings of equity and debt securities, including preparing and filing numerous registration statements with the SEC; 
  • Issuers in preparing private offering memoranda with respect to the issuance and sale of equity and debt securities pursuant to exemptions from federal and state registration requirements; 
  • Issuers and institutional and individual investors in negotiating and documenting of terms and agreements and other documentation with respect to investments in private offerings of common and preferred equity and convertible and subordinated debt; 
  • Companies listed on the New York and American Stock Exchanges and traded over the counter in responding to unsolicited, hostile acquisition offers, as well as in the formulation and presentation to shareholders for approval of anti-takeover charter provisions; 
  • Publicly and privately-owned businesses and institutional and individual investors in connection with purchases and sales of non-real estate related businesses and assets for cash or securities, reorganization and merger and acquisition transactions, structuring the transactions, and negotiating and preparing agreements and related documentation. These transactions involved businesses including manufacturers of industrial products such as machine tools, consumer products such as a major regional ice cream company, textile manufacturers, non-bank financial services firms such as an investment advisory firm managing a family of mutual funds that was sold to an institutional buyer, manufacturers of military equipment, and entertainment businesses; 
  • Privately owned hotel and hotel management companies with annual revenues of $100 million +/- in connection with negotiating and documenting the acquisition and disposition of properties in Ohio, Texas, Florida, Massachusetts, North Carolina and California, of hotel management companies managing properties in multiple states and of franchise agreements with franchisors including Marriott, Hilton, Westin and Sheraton, Days Inn, Ramada, and various limited service franchisors; 
  • A local developer group in negotiating and documenting a joint venture with one of Japan’s largest construction companies and for the development, financing and construction of the 500 room Westin Hotel and underground parking garage contiguous to the Convention Center in downtown Indianapolis, Indiana. This representation included negotiating and documenting various state, county and city economic development incentives and an agreement by the Lily Foundation to finance a $7 million urban park on the roof of the hotel’s parking garage; 

Steve has also served as an independent arbitrator, on a panel with two retired federal court judges, in a binding arbitration regarding a law firm dissolution. 

Banking Law, Regulation and Problem Asset Resolution

While Executive Vice President and General Counsel of one of Ohio’s largest banking organizations, Steve: 

  • Had direct line responsibility for three subsidiary banks and all non-banking subsidiaries, including a majority-owned, publicly registered, small business investment company and wholly owned leasing and capital management subsidiaries; 
  • Served as a member of the corporate credit review committee and a member of the board of managers for the bank’s 1 million square foot headquarters office building; 
  • Direct report for human resources and operations divisions; 
  • Was appointed by the board, during a hiatus between chief executive officers, as a member of a three-person managing committee responsible for the exercise of the authority of the chief executive and the day-to-day operation of all facets of the organization’s businesses; 
  • Was responsible for maintaining the organization’s regulatory relationships with the Federal Reserve, the Federal Deposit Insurance Corporation (the FDIC) and Ohio Banking Department, including the oversight of examinations and resolution of multiple regulatory issues. 

Steve played a lead role in developing and executing strategies to defend against the first two hostile takeovers attempted in the banking industry, including engaging and supervising investment bankers (First Boston) and New York and Washington outside counsel (Sullivan & Cromwell and Arnold & Porter). After the successful defense of the first, using the newly effective Change in Bank Control Act, he negotiated a standstill agreement with the potential acquirer. The organization was acquired in the second contested takeover at a premium of approximately 47% above market and almost 30% over the initial offering price. Following the acquisition, at the request of the acquirer, Steve founded and served as the Managing Partner of a new office and a member of the Executive Committee of the acquirer’s outside general counsel, a 250 attorney regional law firm, in five years growing the office from 1 to 17 attorneys and the most profitable office in the firm on a per capita basis. In addition to office and firm-wide management responsibilities, he also assisted in development of strategic, management and compensation programs and plans. 

In 1988, Steve joined one of the 25 largest law firms in the U.S., acting as its senior financial institutions partner nationally. He utilized his banking experience and national and regional regulatory relationships to develop and execute a firm-wide strategy which resulted in the firm becoming one of the largest legal contractors to the Resolution Trust Corporation (the RTC). He administered the firm’s RTC practice, including maintaining liaisons with the Offices of the RTC General and Regional Counsels. 

In transactions involving billions of dollars and individual and agency credits, Steve represented:

  • Lenders and borrowers in negotiating and documenting loan transactions involving secured and unsecured industrial and commercial credits and real estate credits involving office buildings, hotels and resort properties, multi-family rental housing, condominiums, and industrial, warehouse and distribution facilities; 
  • Lenders and borrowers in the re-negotiation and workout of non-performing loans collateralized by the full spectrum of real estate and other commercial/business assets, including inventories and receivables; 
  • Lenders in the enforcement of guarantees, the disposition of performing and nonperforming assets and the tracing, acquisition of title to and the disposition of real estate and other underlying collateral in both individual and bulk portfolio transactions.

He developed and coordinated systems for financial institutions to select, retain, and manage creditors’ rights, general commercial litigation and transactional counsel in multiple jurisdictions throughout the United States and U.S. Territories, including negotiating and overseeing staffing, rates, progress reporting, performance measurement and evaluation, and billing and payment. 

Steve coordinated the multi-office representation of the RTC in connection with institution closings and seizures, supervisory assisted acquisitions and asset dispositions, and director and officer liability, loan collection and other litigation matters. 

As special counsel to the RTC, he was co-lead counsel in the conduct of a review of all 1988/89 conventional Federal Savings and Loan Insurance Corporation assisted transactions and the preparation and submission of a “Report to The Oversight Board of the RTC and Congress” and in the issuance of a legal opinion confirming the constitutionality of FSLIC assistance. 

Steve played a lead role in several aspects of the special counsel representation of the State of Ohio in connection with the failure of the Ohio Deposit Guarantee Fund (the ODGF), including coordination with multiple other firms of the grant of insurance by the FDIC to certain of the institutions and a special auction of other of the institutions that had been ODGF insured. 

On behalf of distressed insured institutions, Steve negotiated and resolved Memoranda of Understanding, Cease and Desist Orders and recapitalization transactions with various regional offices of the FDIC, state banking departments, the Comptroller of the Currency, the Office of Thrift Supervision (the OTS) and/or Federal Reserve and Federal Home Loan Banks. 

He conducted an independent investigation at one of the largest saving and loans in the U.S., reporting to the CEO and an independent director, regarding alleged violations of banking regulation, including the issuance of a detailed report and presentation of the results of the investigation and the report to the regional office of the OTS. As a result of the voluntary conduct of the investigation and submission of the results to the OTS, the matter was resolved with no regulatory action against the institution. 

Steve also investigated and prepared a report to a committee of independent directors of a banking organization, Federal Reserve authorities, the Enforcement Division of the SEC and the U.S. Attorney’s Office with respect to apparent violations of the Foreign Corrupt Practices Act involving activities of the senior international lending executive concerning the unexplained payment of commissions into a code named account in the Cayman Islands. As a result of the voluntary investigation and disclosure of its results, no regulatory actions were taken against the banking organization, although two of its executives were indicted. 

He represented a banking organization in connection with an investigation by the Enforcement Division of the SEC into the adequacy of loan loss reserve provisions over multiple years and the appropriateness of the process for determining such provisions. The investigation was terminated by the SEC without any action against the organization. 

Steve has represented organizers of de novo banks and bank holding companies, and of purchasers and sellers of banks, bank holding companies and thrifts ranging in asset size from $10 million to $2 billion. The representations included the negotiation and documentation of transactions and the preparation and approval by federal and state regulatory authorities of applications required in connection therewith. 

Steve served as special counsel to directors of a bank in connection with the resolution of U.S. Treasury Department currency violation complaints. 

He has also negotiated and documented executive employment and “golden parachute” agreements for senior executives of insured banking and savings institutions, as well as non-banking businesses, and preparing and documenting cash and stock incentive plans and programs including, as appropriate, preparing and filing with the SEC registration and/or proxy statements, and representing new executives of an insolvent mutual savings and loan in negotiating with and securing required approval of employment agreements by Federal Home Loan Bank regulators.

Management, Business Consulting and Investment Banking

In his consulting and investment banking practice, Steve: 

  • Served as a consultant and investment banker for a start-up business with a proprietary industrial process converting hazardous iron and other metal waste streams into a non-hazardous engineered products material feed with multiple potential applications. The representation included negotiation and documentation of a strategic partnership with an $8 billion per year public company.

The businesses were sold in three separate all cash transactions, resulting in total proceeds to the seller of more than $16 million; 
  • Served as consultant and investment banker to a construction products/home décor company. The client owned a manufacturing facility in Italy using proprietary equipment and processes to produce marble and granite products for use in interior home and commercial décor and external commercial curtain walling applications.

  • Consulted a distressed produce distribution business with annual revenues of approximately $60 million that were in default to a secured lender. He designed, structured, and conducted a sealed bid auction process which, in a three-week period during Christmas and New Year, generated 11 site visits and two non-contingent cash bids substantially in excess of the lender’s initial estimate of liquidation value. The process required the submission of offers by execution of non-negotiable documentation providing for a 30-day close and no seller representations or warranties, limiting due diligence during the 30-day period to the verification of real estate title and the absence of material inaccuracies in a recent lender required Phase One environmental report; 
  • Served as consultant to a family-owned home décor business with annual revenues of approximately $5 million and substantial operating losses.

A $3 million purchase offer was generated from a competitor, which the family elected to decline in favor of the execution of a new strategic plan; 
  • Served as consultant and investment banker to a low tech, proprietary medical training products business. The initial objective was to raise $1.8 million in exchange for up to 50% of ownership. Steve developed and executed a business strategy that enabled the company to bootstrap the pre- investment production of products that resulted in sufficient cash flow to reduce the capital raise to $400,000 for 20% of the ownership. That investment was made by the directors of a community bank identified and introduced to the client as a part of the assignment and which subsequently extended a working capital line of credit to expand the business; 
  • Co-founded, developed, authored and participated in executing a business plan, and assisted in securing an initial equity investment of $10 million from institutional investors, for a business that acquired residential home security contracts from independent dealers pursuant to long term contracts. The contracts required dealers to sell systems only to customers that satisfied established credit criteria, use standard documentation developed as a part of the business plan and to sell to the business one of every three qualifying new accounts the dealers generated each month. The business was sold after a bit more than two years, by which time it had become the 13th largest owner of accounts in the country; 
  • Served as investment banker to a luxury medi-spa business, founded by the former President of Revlon USA, with facilities on Fifth Avenue in New York City, Greenwich, Connecticut and at the Mandalay Bay Hotel in Las Vegas.
