What Our Patients Have to Say

I am a doctor that sees Dr. Yolanda Marcos and her other providers. I have been impressed by all of them. They are knowledgeable and kind. They take their time to get the right diagnosis and prescribe the appropriate medications.

Shawna Deeves

Wait times are excellent, and staff is amazing. I love the doctors, and the P.A. They take pride in their care. Most of the staff is friendly, and have excellent bedside manner. I highly recommend this doctor, and office. However the folks in the front could do better about greeting with patients.

Cynthia M Gardner

Been to several places since I left the military and Marcos Medical is the best by far. My PCM is awesome and I can do everything at one place. I highly recommend for primary care.

Penny LaFlam

I have had the most excellent and compassionate care from Dr. Marcos and her remarkable staff. I have seen her for at least 5 years and highly recommend this practice as the best care in San Antonio.

Cindy Rouch

Dr. Marcos and her staff are exceptional. I have been a patient for more than 20years. I found Dr. Marcos after a serious health scare at 40. I had several risk factors from diabetes to high blood pressure and serious cardiac issues. Because of her persistent medical care and expertise, my life has changed drastically for the better. Her medical practice took care of my medical needs under one roof.

Veronica Benson

Marcos Medical has been my primary care provider for the last 4-5 years and the customer service / level or care is consistently excellent. They have gone out of their way to help me during extended business trips, vacation, and other circumstances outside the norm. I wholeheartedly recommend them.
