About Dr. Kristen Williams, MD
​Aesthetic Director

Dr. Williams is our primary provider in our Lutz clinic and sees patients Mondays, Wednesdays and Thursdays. On Tuesdays she sees patients in our St Petersburg clinic. She sees patients for medical weight loss, hormone replacement therapy and is also our Aesthetic Director for the practice. She oversees the development of our aesthetic services and is an experienced injector through Allergan, Galderma and MINT PDO threads. Dr. Williams goal with our aesthetics program is to help every patient age gracefully and naturally through the use of bio-stimulators, neurotoxins and cross-linked hyaluronic acid dermal fillers. Many of our aesthetic services are geared towards boosting collagen production so that our patients can obtain a more natural and long-lasting result.
Dr. Williams has introduced collagen boosting procedures such as Sculptra Aesthetic and Plasma Pen Skin Tightening to the practice, along with collagen boosting skincare treatments, including PRX Glow and Microchanneling. Since she took over as our Aesthetic Director, we have also expanded our range of dermal fillers, skincare products and neurotoxins. New aesthetic patients should first book an Aesthetic Consultation with Dr. Williams in either our Lutz or St Petersburg clinic prior to any aesthetic treatment. Each Aesthetic Consultation is 30-minutes long and Dr. Williams provides a comprehensive plan to target specific goals set by the patient.
Dr. Williams graduated medical school in 2010 from Florida State University, but her interest in anti-aging medicine was seeded a long time before that. After her undergraduate studies, Dr. William did her thesis on obesity for her Master's in Public Health. After she finished her medical degree, she completed a residency program in 2014 at the University of Florida Shands Hospital in Jacksonville, FL. She approaches medicine from a patient-centric prospective and some of the qualities patients appreciate most about her is her compassion, encouragement and listening skills. Since 2014, Dr. Williams has focused more on anti-aging medicine, receiving certifications in aesthetic medicine, including Botox, Sculptra, MINT Thread Lifts and most recently, the Nonsurgical Lip Lift (NLL) in 2021. In 2021, she also became Board-Certified in Aesthetic Medicine through the American Academy of Procedural Medicine. Outside of medicine, Dr. Williams is a big football fan and enjoys spending time with family.
