Successful delivery of healthcare is not a zero-sum game. I believe in win-win scenarios between patients and the Managed Care Industry.
For the past 20 years I’ve provided value-based healthcare solutions for physicians and health plans that emphasize both the clinical benefit for the patient and the economic benefit for the payer. I’ve established contracts that create affordable access to therapies for patients and shift treatment paradigms for both the clinician and the health plan.
I live in San Diego with my beautiful wife, Lindsay. We spend our days hiking or at the beach, as most San Diegans do.
We live in an increasingly finite world, but that only makes our mission to provide the best, most affordable healthcare more important.
