Medical Staff

We are thrilled to offer you the services of our amazing medical staff team.  As we say here at The G Spa, teamwork makes the dream work!

Dr. Kathleen GriffinKathleen Griffin, MD, Medical Director

Dr. Griffin is a board-certified OB-Gyn graduate of UCLA School of Medicine, Fellowship trained, and has been a Certified Menopause Clinician for many years.  Practicing for over 25 years has given her the expertise to provide a comprehensive, holistic approach to patient care.  Her current focus is on enhancing self esteem through aesthetic medicine, and she continues to offer expertise and specialized care with our medical weight loss program and to provide limited gynecology services, which include consultations for menopause, thyroid dysfunction, depression, PMS, annual evaluations and body image consultations and improvement.

Dr. Griffin believes in empowering patients through education and loves patients with lists and patients who “Google.” She has found that improvement of one’s exterior can often be as important as addressing the concerns of traditional “internal” medicine.  She believes that enhancing one’s beauty or good looks is more about maintaining one’s sense of self-worth and self-confidence than vanity.

Dr. Griffin’s passion for empowering women and offering them the best medical care naturally led her to specialized training in Medical Aesthetics, skin care technology and treatments. Convinced that her patients wanted and needed “external” care coupled with internal care from a staff they could trust, Dr. Griffin decided to add spa medicine to her medical practice.

Her practice, The G Spa, in Santa Barbara is an award-winning practice in the field of Medical Aesthetics.
