    How was your appointment with Dr. Marks?

    Jul 30, 2021
    This is the best doctor in San Antonio, Myself, a retired doctor, couldn't find any physicians to workup and diagnose my lung problems. As a physician I found this unbelievable. A colleague told me I should see Dr Marks. Dr Marks spent more time with me than any doctor I've known. He tediously went over tests that had been done by other doctors and found some mistakes they made. He quickly tested me and did a heart/lung catheterization on me. Turns out, I have a very serious lung problem that no other doctor recognized. His intercession, formal medical logic and clinical prowess came to bear. He saved me and got my life back on track. It was also appreciated that he is serving our country as an Active Reserve Flight Surgeon -- only adding to his heavy schedule but believing in service before self. If you have a lung problem, or trouble breathing, look no further! He easily earns 5 stars.
