David K., Litigation Partner, Multinational Tier 1 law firm

Roger is the health care lawyer you want advising you on your most important matters. He brings calm, clarity, and judgment that consistently turns hard problems into smart, executable solutions.

I have worked closely with Roger since 2019, across high-stakes matters in the health care and life sciences sector. He is a rare combination of deep subject-matter expertise, steady leadership under pressure, and genuine collegiality. Roger’s expertise extends to all aspects of corporate governance, corporate finance, mergers and acquisitions, and navigating through distressed situations. He also excels at unraveling the regulatory thicket—FDA, fraud and abuse, privacy, reimbursement, and beyond. Roger translates that complexity into practical strategies that align legal risk with business objectives. Time and again, he has anticipated issues others missed and resolved them before they became problems.

Roger’s counsel is both rigorous and commercial. He is as comfortable advising boards and C-suites on enterprise risk, compliance programs, and bet-the-company disputes as he is guiding operational teams through day-to-day questions. In crisis scenarios—investigations, enforcement actions, product issues, or sensitive transactions—his judgment is unflappable and his guidance is actionable. He is solutions-oriented without cutting corners, and he operates with the highest integrity.

Matthew S., Restructuring/Litigation Partner, AmLaw200 law firm

Roger is the go-to health care counsel to obtain business-oriented practical legal solutions from someone who has operated in the trenches during the most difficult situations that a company can encounter during its life-cycle.

I have worked with Roger since 2023 on all facets of a complex out-of-court financial restructuring of a health care company balancing the competing interests and personalities of secured lenders, trade creditors, management, employees, and equity holders, while preserving going concern business operations in the face of severe liquidity constraints. Roger’s skill and legal expertise was essential to navigating the myriad of issues that arose on a weekly basis. Combined with a keen ability to tailor his counsel to the company’s ability, need and ultimate objective, Roger adeptly advised the company through multiple financing negotiations, management transitions, related corporate governance and risk-mitigation issues, employee retention, supply chain contract negotiations, joint ventures agreements and disputes, and merger and acquisition processes. Through it all Roger maintained a steadfast and unflappable resilience that is critical to the company’s continued operation.

I recommend his guidance wholeheartedly.

I have had the opportunity to work both with Roger in his role as GC for a Med Device portfolio firm and as an external legal consultant for a different and separate European MedTech firm. My experience with Roger dates to 2019.

As GC, Roger was able to advise on all legal matters both internal and external. He was extremely balanced with the needs of the business while assessing all risk-related challenges. He dealt with government oversight challenges, internal fraud investigations, reimbursement, any corporate governance situations and all employment issues. Roger provided all positions in a calm, balanced and professional tone. He is firm on the risks and offers multiple directions for the best possible solutions.

Roger is very collaborative as he brings clients along stressful pathways with clarity and confidence. He always asks the right questions to help frame the discussion all while creating strategies for next steps with positive outcomes.

As the leader of a business, it has been comforting to have access to Roger. The most successful teams have strong diverse talent. Roger fits into any leadership discussions with positive insights and an eye to the risk-related items. No issue of any size gets past his reviews. If you are looking for high quality legal advice in the MedTech industry on a very wide range of topics, you will feel great comfort relying on Roger.

Duane D., Global Divisional CFO for a Multinational Medical Equipment Manufacturing Company.

I had the privilege of working with Roger for more than four years while serving as CFO and COO of a private‑equity–backed cancer and pre‑cancer diagnostics company where Roger was serving as General Counsel. Throughout that time, Roger proved to be an exceptional business partner—commercially minded, solutions‑oriented, and deeply committed to enabling growth.

Roger brings broad and sophisticated legal expertise across a wide range of areas, including vendor and partner negotiations, HCP arrangements, litigation strategy, intellectual property development, capital acquisition, and debt restructuring. He consistently managed multiple complex workstreams with precision and ensured that all stakeholders were aligned through clear, timely updates.

What sets Roger apart as an attorney is his ability to simplify complexity. He translates intricate legal issues into straightforward, actionable guidance that empowers teams to move confidently and decisively.

Roger’s counsel was invaluable to our organization, and I trusted him to always act in the company’s best interest. To this day, I continue to rely on his sound judgment and expertise. I recommend him without hesitation.
