My Philosophy and Approach to Wellness...

I am board certified in family medicine and geriatrics, allowing me to better serve the entire family. I have been practicing for 35 years in different models of care and am excited to be affiliated with MDVIP and offer a more personalized, practice approach to patient care.  In my primary care practice, I have more time for the patient and patient-physician relationships which is different than in most traditional medical offices. My practice also stresses healthier behaviors and activities, which I believe in strongly.

The cornerstone of the practice is the MDVIP Wellness Program Plus, comprised of advanced diagnostic tests, including a heart disease screening developed with Cleveland HeartLab and a brain health screening, that can help detect certain risk factors earlier, along with a personalized medication management program to help make your medication use safer and more effective. In addition to preventive services, this practice model allows for same-day or next-day appointments that are not rushed and start with minimal waiting. Patients also have the ability to text/call me on my cell phone for more urgent needs. 

I am affiliated with San Antonio Regional Hospital and Casa Colina Hospital & Centers for Healthcare.


 It is important, now more than ever, to have a primary care doctor who has the time and resources to care for you personally and proactively. Watch this video to hear more.

I love Dr. Fagan for many reasons but one particularly stays in my heart. In 2004 Dr, Fagan was taking care of my mother.
