Our TEAM

About The Practice

Great Life Medical has been proudly serving our community since 2019, continuing a legacy of care that began with Michelle Zarzana’s first clinic in 2003.

With over two decades of experience helping patients achieve better health through integrative and regenerative medicine, our team remains dedicated to personalized, results-driven care.

We’re also proud to accept most major PPO insurance plans, such Aetna, Blue Cross, Blue Shield, Anthem, ILWU, and many others – including MediCare – making it easier for patients to access the care they need to live their healthiest lives.
