The Medical Vein Clinic Story
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.
Our lead physicians, Dr. Hogg and Dr. Josue Medina, have a depth of experience and accreditations in their field. Both are board certified by the American Board of Radiology, members of the Texas Medical Association, Bexar County Medical Society, Radiological Society of North America, Society for Vascular Ultrasound and the American College of Radiology.
Additionally, both physicians are diplomats of the American Board of Venous and Lymphatic Medicine, hold certifications as Registered Vascular Technologist (RVT) and Registered Physician in Vascular Interpretation (RPVI). Dr. Hogg is also registered by Cardiovascular Credentialing International as a Registered Vascular Sonographer (RVS), and as a Registered Phlebology Sonographer (RPhS).
