Mark Hueppelsheuser, ESQ

General Counsel
Admitted to the California bar in 2012, Mark has served as The Oncology Institute’s general counsel since 2015, playing a key role in the practice’s unprecedented growth and improvement in that time. Over the past several years Mark has created and enforced a robust and highly vetted compliance program, managed numerous practice acquisitions, industry leading external counsel, private equity investments in the practice and, most recently, The Oncology Institute’s efforts to successfully take the practice public to create further growth and an improved patient experience.

Prior to joining The Oncology Institute Mark earned his B.Sc at The University of Alberta with a dream to serve patients in the health care space. Mark then completed his J.D. at Chapman University’s School of Law, going on to earn his LL.M at America’s top legal dispute resolution program, Pepperdine Law School’s Strauss Institute. During that time, Mark gained experience in civil litigation and went on to become a member of Quiksilver’s legal team, reporting directly to the global general counsel and helping to manage the legal responsibilities of a multi-billion dollar global enterprise. Mark is also proud to have volunteered countless hours over several years successfully mediating contentious cases in the Orange and Riverside courthouses in an effort to give back to the community he is proud to call home.
