Direct Primary Care + Skin Rejuvenation
Meet Our Doctors
Direct Primary Care cuts the middleman out of the doctor-patient relationship. No insurance means that WE work for YOU. In DPC, insurance is saved for emergency and specialty care and that saves you money.

Dr. Rachel Walker
Dr. Rachel Walker is a board-certified Family Medicine physician proud to serve the Alamo Heights community. Prior to joining Alamo Heights Direct Primary Care, Dr. Walker practiced value-based primary care in central San Antonio where she managed acute and complex chronic disease in adult and geriatric patients.
Dr. Walker decided to transition to Alamo Heights Direct Primary Care to restore the time and attention that quality primary care deserves, free from the limitations of traditional insurance-based models. Practicing within the DPC model allows her to provide accessible, personalized, and unrushed care. With transparent pricing, extended visits, and direct access to the physician, she is committed to removing the barriers that often stand between patients and high-quality primary care. Her goal is to restore the kind of meaningful, long-term doctor-patient relationships that truly make a difference in people’s health and lives.
With a strong focus on preventive care and early detection, Dr. Walker encourages patients to lead active, full lives. Whether managing complex health needs or helping patients stay ahead of potential issues, she strives to ensure each patient feels empowered and supported throughout every stage of life.
When she’s not in the clinic, Dr. Walker is wearing burnt orange. A proud University of Texas alum and devout Longhorn fan, Dr. Walker rarely misses a fall football game. In her spare time, you can find her walking her Labrador, Maxwell, around the neighborhood, or escaping to the outdoors with her husband to fly fish, hunt, or hike.
