Erin Reese, M.D.Medical Director
I received my Bachelor of Arts degree in English Literature from Baylor University in Waco, Texas. I then went on to earn my Doctor of Medicine degree from the University of Texas Health Science Center at San Antonio. I completed my Internship and Residency at Baylor University Medical Center at Dallas and I had the privilege to serve as Chief Resident in my final year. I am certified by the American Board of Internal Medicine.

Upon completion of my Internship and Residency, I practiced as a hospitalist for 1.5 years at Baylor University Medical Center at Dallas. There, in addition to caring for my patients, I served as adjunct faculty in the simulation lab teaching medical procedures to 3rd and 4th year medical students from Texas A&M. I returned to San Antonio when I joined iMed Healthcare Associates where I practiced for almost 7 years. You can learn more about me and read reviews from happy patients on my Healthgrades profile.

I grew up in Pearland, Texas and I have happily lived in Texas all but 9 months of my life. I am a proud mother to my son, Bobby, and I love spending time with him. I greatly enjoy spending time with my parents who live here in San Antonio. When I am not taking care of my patients or spending time with my family I enjoy running, reading and cooking and I have a great appreciation for music and theatre.

Liz Diaz
Liz started her career in the medical field in 2000 as an Optical Technician. Since then, she has worked in cardiology, urology, neurosurgery and Internal Medicine which has been her favorite because of the breadth of medical conditions she gets to learn about and help treat.

She has a natural gift as a caregiver and brings tremendous kindness, patience, and empathy to her daily interactions with patients.

Working in the Concierge setting has brought Liz a new sense of joy in her work. She greatly values the fact that her interactions with patients are not rushed, so she is able to get to know her patients more completely. She enjoys the extra time that patients are able to spend with Dr. Reese in the concierge setting because it fosters stronger relationships between the patients and the entire staff. The office feels more like a home than a clinic.
