About Optimal Medical Group

Dr. Juan Chavez and Dr. Mireles-Chavez have been practicing medicine for almost twenty years in the Fresno, California area in the private and hospital-based setting. Both have developed a deep appreciation for the need for preventative and restorative age management medicine based on proven evidence-based medical research that includes balancing the whole body including nutrition, exercise, and hormone optimization. Together with our fitness trainer, Jennifer “JZ” Zerling, and Health Coach, Samantha Kellogg, we tailor plans to help you achieve your optimal health. We practice these same strategies and programs in our own lives and have seen a remarkable difference in our overall health and that of our families.

We are also pleased to be expanding our services with a comprehensive Medical Weight Loss Program. Dr. Juan Chavez is certified in Obesity Medicine and will head up our efforts to help the residents of the Central Valley achieve optimal health through non-surgical weight loss.

In addition to our Age Management and Medical Weight Loss Programs, we are offering a variety of new services to enhance your life. We have some of the best technology available including state-of-the-art lasers and the latest in Platelet Rich Plasma (PRP) therapy with BioD. These services can enhance your appearance helping you look and feel fabulous.
