Dr. Timothy Straight
San Antonio Board Certified Skin and Vein Clinic
A dermatologist is a medical doctor who specializes in diagnosing and treating skin, hair, and nail conditions. This includes everything from common concerns like acne, eczema, and rashes, to more complex medical issues such as skin cancer or autoimmune skin diseases. At Texas Skin and Vein, we also offer advanced cosmetic treatments for clients seeking aesthetic improvements such as wrinkle reduction, scar treatment, and clearer, healthier skin overall.
If you’re dealing with persistent skin irritation, hair loss, nail changes, or simply want a professional opinion on your skincare, it may be time to schedule a visit. Annual skin exams are also recommended, especially if you have a history of sun exposure or skin cancer in your family.

EXCELLENT Based on 451 reviews Posted on Lorena MenchacaTrustindex verifies that the original source of the review is Google. I always prioritize how thorough the staff is — and this place exceeded my expectations. Alex went above and beyond to ensure all of my questions were answered, even after my appointment with Dr. Martini. Her professionalism and exceptional customer service truly stood out. I highly recommend this office to anyone looking for a team that genuinely cares and takes the time to support their patients!Posted on Esmi NoneTrustindex verifies that the original source of the review is Google. I was unsure of what to expect when it came to doing laser hair removal. Mari and Dr. Straight answered all of my questions and were able to fit me in same day to get the procedure done. Mari goes out of her way to make you feel comfortable and ensure you feel as little pain as possible. She finished and I felt maybe 1 tiny pinch enough that I thought..... was I tricked?. Well I am back on my 2nd visit and the hairs dissappeared! Amazing thank you Mari!Posted on VanessaTrustindex verifies that the original source of the review is Google. Very courteous staff and professional. Taking care of facial needs. Mari a great help and i will definitely recommend this clinic to friends and family.Dr Martini always listens to my concerns and always finds alternatives if something is not helping mePosted on Chris JTrustindex verifies that the original source of the review is Google. I am extremely grateful and impressed to know that Dr. Straight is now my wife’s doctor! After watching my wife suffer with swollen feet/ ankles, and seeing so many doctors in the past I had issues. No one could seem to help find a remedy to take this away. So we continued praying asking God to lead us! And He most certainly did! My wife’s appointment was a referral from Dr. Michael Maloy (another great doctor) to see Dr. Timothy Straight for feet and ankle swelling. He informed her that it was urgent that her current medication of Taltz be discontinued and she start using another medication that he prescribed. He also said to give it a few days and it she work. My wife waited and she was at a place where we had to buy little flat shoes for her to wear. None of her shoes fit. To make a long story short. After approximately 72 hours she woke up and the swelling was gone!!! I am so happy to see her not suffering for now. Maybe it isn’t completely over yet- but there is light at the end of this tunnel!! Thanks Dr. Straight (The Colonel)!Posted on Kristi BrowningTrustindex verifies that the original source of the review is Google.
