About Us

Upper Echelon Medical in Fullerton, Orange County, East LA, and Inland Empire, California, provides comprehensive primary care services to patients of all ages living and working in the local community. Experienced physician Marisse Herrera, DO, and her team run a forward-thinking practice that emphasizes using new technologies to empower patients and enable them to make better health and lifestyle choices.

Care Tailored to Your Needs.

Upper Echelon Medical’s team of osteopathic doctors treats patients as a whole rather than focusing on a specific disease and believes in promoting the benefits of a healthy lifestyle before considering medications. The team also uses drug-free osteopathic manipulative techniques to help treat upper respiratory infections, headaches, back pain, muscle pain, and more.

For those patients who need medications to treat or help manage their condition, Upper Echelon Medical offers prescription dispensation, providing medicines at wholesale prices that save patients hundreds of dollars. This service is part of the practice’s direct primary care model, where patients pay a monthly fee rather than going through insurance companies.
