Dr. Hogg & Dr. Medina | Board Certified Physicians

The Medical Vein Clinic Story

Medical Vein Clinic was started to give patients suffering from vein disease an expert and caring medical treatment home. Our clinic’s founder, Dr. John Hogg, spent three years visiting other vein treatment centers around the United States to identify the best practices to bring to San Antonio. Since we opened our clinic doors in 2017, we’ve helped 1,000’s of people---and their legs----feel and look better.

We want our patients to feel relaxed and cared for.

People tell us that our clinic seems more like a spa than a medical clinic. That is by design. We want our patients to feel relaxed and cared for. Our medical team has some of the most experienced vein specialists in the country. We have invested in the latest technology and equipment to treat vein disease. And, our clinic’s support staff is friendly, knowledgeable and treats every patient like family.
