About Us


Healthcare the way it should be.

The best part of my work as a physician has always been connecting with people and helping them through their hardest days. However, within the traditional medical model, taking time to connect is sometimes difficult to do. 

At Link Primary Care we change that. We take time to create trusted partnerships with our patients, so we can fulfill our purpose: helping our patients live their healthiest, happiest lives by giving them the personal attention and access that they need.

It’s concierge medicine for everyone – because everyone deserves it.

Erica Yalavarthi, MD

Family Medicine Physician

Hello! I am Dr. Yalavarthi, a Board-Certified Family Medicine Physician. I graduated from University of Missouri-Kansas City School of Medicine and completed my residency at Baptist – Lutheran Medical Center in Kansas City. After residency I moved to St. Louis with my husband to be close to family.

My goal in this direct primary care practice is to provide personalized, cost-effective, and cost-conscious healthcare to my patients all while loving my job. I am excited to spend time with my patients, making decisions together based on the best evidence available. While I treat both acute and chronic conditions, I am a big proponent of preventive care. Keeping you healthy through nutrition, exercise, and mental well-being is just as important as treating an illness.

My husband and I have 3 children and two dogs. In my free time, I enjoy watching my kids at their sporting events, playing tennis, running, reading and being with my family and friends.
