It’s always a good experience coming to this practice with helpful, friendly, courteous staff and amazing physicians. It’s always a pleasure seeing Dr Kathleen Welsh, she’s an extremely caring person and an excellent doctor.
Dr. Welsh and her staff are amazing. Love and care for both body and soul. After my treatment I walked out looking and feeling my best. Thank you!
This has been my dermatologist provider for 20 years. Dr Welsh has caught numerous skin issues for me. She is friendly, talented, caring and has the best memory of anyone I’ve ever met. Highly recommend this office!
I have been seeing Dr. Welsh regularly since I was 30 years old. I am now 50 and always feel confident telling people my age because they are always shocked and say they thought I was in my late 30’s, early 40’s. The only downside to going to this office is knowing that one day Dr. Welsh will retire. Dr. Welsh is hands down the best cosmetic dermatologist around. I love referring my friends to her as they are always thrilled with the results. Thank you Dr. Welsh!!!
I’ve been a SFBAD patient for more than seven years and have received superb medical and cosmetic dermatology care for several conditions, including rosacea, sun damage, actinic keratosis, and plain old aging skin. Dr. Austin, Dr. Welsh, Nurse Katie, Concierge Julie, and other staff members are a gift. Thanks to their expertise, I look a whole lot better now. And thanks to their eagle eyes and careful follow-up, I am healthier. I am so grateful!
