Biography

James Dinn, DO knew he wanted to be a physician at age 5. When his brother was diagnosed with a chronic illness, his family spent years looking for a physician who would simply listen. Today, Dr. Dinn strives to be a physician who truly hears his patients.

Dr. James Dinn is a Texas native; he completed the entirety of his medical education in San Antonio. He attended the University of the Incarnate Word School of Osteopathic Medicine and graduated with honors before completing his Internal Medicine residency at the Texas Institute for Graduate Medical Education and Research. His care philosophy embraces intentional listening, which he believes greatly aids in making diagnoses. Dr. Dinn enjoys that medicine is both an art and a science.

During his training, Dr. Dinn served as Chief Medicine Resident and was awarded Resident of the Year. As the Director of Ambulatory Education, Dr. Dinn is dedicated to internal medicine and is involved in mentoring and teaching residents and developing real-world educational materials to help prepare future physicians. In his time outside of work, he enjoys gardening, cooking, playing cards, trying new restaurants, spending time with family and taking care of his dog and saltwater fish.

    Dr. Dinn is attentive and gives me the sense that he is treating me as a whole person. He has been sensitive to all of my concerns and has taken the time to really listen and then sometimes educate me in order to give me peace of mind. He has made test, treatment plan and referral recommendations all in partnership with me as a patient. It appears to me that he has both the professional acuity and the the resources available to him to warrant the trust I have placed in him as my PCP.

    He's a great doctor very patient knowledgeable Respects my opinion on over prescribing too much medication In other words in my opinion the Cure is worse than the affliction.. I just. attended a funeral of [omitted] man very active for his age but died of constipation. I don't blame his doctor he is just not trained in making sure metabolically his patient is safe. Constipation is totally preventable. .
