About Dr. Pierce


I was born and raised in South Texas. After graduating from the University of Texas – Pan American for college and Baylor College of Medicine for medical school, I traveled north to Santa Rosa, CA, for training in family medicine. Since graduating in 2007 from the Santa Rosa Family Medicine residency, I’ve had the privilege of teaching residents and caring for patients in outpatient clinics, hospital wards, and emergency rooms in northern California. I have additionally had the honor to care for families affected by HIV, malaria, tuberculosis and malnutrition in the countries of Lesotho, Malawi, South Sudan, and Kenya. I completed a global health fellowship and currently practice high risk and surgical obstetrics in Martinez, CA, where I have the pleasure to teach outstanding doctors in training at the Contra Costa Regional Medical Center. During my time at CCRMC, I was introduced to and became a firm believer in the power of plant-based medicine. I learned that with the right information and motivation, people could get to the root cause of their illnesses and cure themselves. In 2020, I started my sole-provider practice in lifestyle medicine, using the power of a whole food, plant based diet along with exercise and other lifestyle techniques to prevent, treat, and reverse chronic disease. I have been a vegetarian since 2000, initially motivated by the mistreatment of animals in our food system. Since then I have learned much more about how a plant-based diet can help heal ourselves as well as the planet.


I am a board certified family physician by the American Board of Family Physicians, continually since 2007. I am also board certified in Lifestyle Medicine by the American Board of Lifestyle Medicine, since 2021.

Lifestyle Medicine Focus

I am passionate about using lifestyle medicine to help people get healthier, get off of medications, and live longer, fuller lives. I see patients with the following conditions: overweight and obesity, diabetes, hypertension, cardiovascular disease, high cholesterol, fatty liver disease, chronic kidney disease, autoimmune diseases such as arthritis, multiple sclerosis and colitis, as well as gynecological conditions (such as menopause and endometriosis), certain cancers, depression, early dementia, and others. I have special training in obstetrics and love working with patients to share the benefits of plant-based eating to support a healthy pregnancy. And I am happy to see healthy people who just want to stay healthy and live a long, long time.

Additional Practice Interests

I continue to practice high risk and surgical obstetrics in Martinez, CA, where I have the honor of teaching the excellent family medicine residents of the Contra Costa Family Medicine Residency. In addition to obstetrics, I teach point-of-care ultrasound through the Global Ultrasound Institute (www.globalultrasoundinstitute.com), as well as mentor residents in global health. My family and I also grow as much of our own food as possible. We see tremendous benefits of tending a garden. For more details, see my garden page link at the top of this page.


“This man embodies the true meaning of physician – someone who endeavors to heal. His level of care is unprecedented. He isn’t just interest in treating your “disease”, but is interested in treating you! The difference is heart-warmingly noticeable! Thank you Dr. Pierce!!”
