Dr Menchaca is a very good doctor. It took me years to find him. Seems like most doctors have an over load and they just want to get you in and out. Not this one he listens to how you feel. And then he tells you what he thinks. He is awesome he is not in a hurry to get you out he will be late to his next appointment if he has to.Try's very hard not to but if so he will. I like how he listens to me about what I think even though I'm not always right. I am glad your my Doctor thank you so much for all you have done for me. I am very thankful. [NAME REMOVED]

This is my third appointment with Dr. Menchaca and as in the past he was attentive to my concerns and ailments. He took the time to carefully check on me and asked me many questions to understand what the problem was. Afterwards she showed me a couple of computer images and pointed out graphically where he believed the problem originates. Dr. Menchaca explained to what the course of action was in order to solve/alleviate the pain. He ordered X-rays and bloods tests. In addition to his professional care he is also very human, polite and courteous.

Dr. Menchaca is a wonderful Internal Medicine Physician! He is judicious about writing prescriptions for symptoms, which I like. He's an excellent listener. I don't feel like I'm rushed during my appointment. Internal Medicine is a bit more complex than Family Practice, in my opinion and an office visit may take longer than 15-20 minutes. With his caring, observant manner, Dr. Menchaca is effective in his diagnosis and will refer you to a specialist right away, if needed. I can recommend Dr. Menchaca to anyone considering a move to Internal Medicine, if you don't want to take lots of prescriptions to mask symptoms, and want a caring Provider who listens to you.

My husband and I very much appreciate the excellent care we receive from Dr. Menchaca. He is very caring and thorough in his treatment recommendations and often personally follows up with us after an appointment or medical test. He carefully explains the side effects of medications and is conservative about prescribing them. Every member of his medical team is friendly, welcoming, and competent.

Dr. Menchaca is knowledgeable, a great problem-solver, kind, a clear communicator, and humble. For example, he checked with colleagues after I left to consider all options for my ongoing infection. He then called me later that evening to discuss his new findings and made suggestions for how I could receive the new treatment the very next morning. After he called back, my husband (who had been at the appointment with me) and I simultaneously looked at each other and said, "He's REALLY good (at his job)." It's such a relief to have excellent health care providers like Dr. Menchaca when you're not feeling well and have brain fog with an ongoing problem. Thank you for your good work!
