In 1994, she began her Dermatology preceptorship at Beverly Hills Dermatology Associates, where she was rigorously trained for 3 years in all aspects of dermatology, to include skin cancer screenings, skin cancer treatments, mole checks, surgical and cosmetic procedures. Jasmine was one of the first PAs in California, who helped set the standards and values for her profession, helping pave the road for many, who aspired to follow in her footsteps. She has mentored and trained many PA students and graduate PAs in all aspects of dermatology for the past 28 years of her career.

In 1997, Jasmine was the first PA to join a group of physicians at Dermatology Associates of Westlake Village, a national training facility for Allergan, the makers of Botox and Juvederm.

Jasmine’s skills, coupled with her advanced techniques and wide base of knowledge, has earned her the respect of the Dermatological Medical Community, and has developed a loyal patient following. In her own words, “I am committed to providing quality personalized healthcare to all my patients, because it’s a reflection of how I would care for my own family and friends. Experience and training have taught me to be both thorough and comprehensive in caring for them. I am always committed to my patients’ well-being, paying attention to detail, and offering them a range of dermatology services and procedures. I believe there is artistry to cosmetic dermatology and I strive to achieve natural results, so that everyone will notice, but noone will know!"

Additionally, Jasmine has developed a line of organic hemp skin and wellness products to further help perfect her patients’ health and skin care needs. Her ultimate goal, as a health care provider, is for everyone to have a chance to achieve great health and happiness.
