Our Team



Dr. David Dorfman


As one of Southern California’s most highly-trained and successful surgeons, I have committed my professional practice to providing patients with revolutionary medical care, cutting-edge alternatives, expert guidance, and unparalleled results. Having had the privilege of working with world-renowned surgeons, I developed an artistic talent in my cosmetic practice, where I am adeptly attuned to my patients’ aesthetic concerns and goals.

My detailed consultations reflect my desire to create a compassionate, supportive experience for patients exploring tailored outcomes through highly customized surgical planning. Every day, I work diligently to help patients look and feel their best, performing breast augmentations, rhinoplasties, mommy-makeovers, facial contouring, liposuction, and numerous other cosmetic procedures to improve overall appearance. Men and women alike benefit from the many surgical and non-surgical procedures performed in the office and at the surgery center.

Born and raised in Southern California, I’ve always had an undeniable passion for the beauty, health, and fitness industries. I’ve been a licensed Medical Ultrasound Technician for 10 years, and pride myself on my detail-oriented approach to keeping clients informed before, during, and after Ultherapy procedures.

Dana Riccio

Medical Aesthetician & Phlebotomist

I've had the pleasure of working with MySkin Medical Spa since 2014, where I collaborate directly with Marichelle and team on developing custom skincare protocols. You’re most likely to meet me before a cosmetic procedure at which time I treat ongoing conditions and prep the skin for what’s to come. Utilizing physician-dispensed cosmeceuticals in conjunction with personalized facials and peelsheal practices, I ensure that you always leave our spa with nourished skin that radiates natural-looking beauty and youthfulness. I look forward to working with you!

Kathleen Bowman

Client Coordinator



Susan Cianciulli

Client Coordinator

As a Coordinator here at MySkin Medical Spa, I work closely with Dr. Dorfman to ensure a comfortable, safe, and enjoyable experience for every patient as we progress toward their desired outcomes. I have an extensive background in the aesthetics and cosmetic industry and am thrilled to be part of a practice where I can confidently refer colleagues and friends to Dr. Dorfman’s expert artistic and surgical care.

I am proud to bring nearly two decades of exceptional customer service to the practice, where I do everything from scheduling treatments to coordinating follow-up care to facilitating each patient’s ongoing communication with Dr. Dorfman regarding individualized surgical issues. But my true superpower is putting minds and nerves at ease. It’s always my goal to be an ally and advocate for patients, while supplying them with answers to their questions, access to their physician, and reminders about important aspects of each unique care plan.


Outside of the practice, I’m a lover of all things beautiful, including fashion, denim, and Southern California sunshine! I hope to have the opportunity to meet you soon and help you along your MySkin journey.
