Our Aesthetic Experts

Roxanne Cornelius, PA-C

Aesthetic Expert

Roxanne-Injector Coat
Roxanne is a board-certified, multi-state licensed physician assistant who specializes in aesthetic medicine. She has been a guest lecturer for resident doctors and currently serves as a prestigious, invited member of the Injector Trainers for Allergan Medical Facial Aesthetics (the makers of BOTOX®, Juvéderm®, Voluma®, and Kybella®). In this capacity, she has the privilege of instructing doctors, nurses, and other medical professionals in the art and science of injecting BOTOX®, injectable fillers, and Kybella®. In 2010, she established Aesthetic Excellence, LLC, to further provide aesthetic training to medical professionals.

Roxanne graduated summa cum laude from the University of St. Francis in Ft. Wayne, Indiana, where she obtained her medical degree as a physician assistant. She has practiced medicine as a PA for nearly 20 years and worked in a variety of medical settings, but her passion has always been aesthetic medicine and plastic surgery. In more than a decade of practicing as an aesthetic PA, she has injected thousands of patients with BOTOX® Cosmetic and dermal fillers and has consistently enjoyed a very high rate of patient satisfaction. Roxanne's education and background, combined with her skilled techniques and gentle touch, complement the work of our plastic surgeons and make her ideally suited to be an injection, laser, Kybella®, and Ultherapy® specialist. She is committed to assisting patients who want a non-surgical approach by teaching them about their aesthetic options, including associated risks and benefits, and allowing them to make informed choices to more fully participate in their own aesthetic care.

"I am always competing with myself to provide the best, safest, most current, and comfortable injection and laser procedures for my patients in a relaxed and professional atmosphere. Each patient is unique and has specific concerns, which I strive to address with compassion, excellence, and artistry. I believe in a natural look: 'you, only better' and Ďbeauty at every age.' I am SO blessed to have a career that I absolutely LOVE and can't imagine anything more fun and rewarding than helping my patients look as good as they feel!"

Her professional affiliations include the American Academy of Physician Assistants, Michigan Academy of Physician Assistants, Society of Plastic Surgery Skin Care Specialists, American Academy of Aesthetic Medicine, and American Society of Lasers in Medicine and Surgery.
