Kay Nehrbass, RN

Kay has been an integral member of Lehman Advanced Dermatology since our opening in 2017, caring for our patients before, during and after their procedures. As an RN for 35 years and nurse injector for 15+ years, Kay has become well respected among our patients. She is a knowledgeable and compassionate partner and her commitment to providing the best experience is observed by all. Kay combines her thorough knowledge of facial anatomy, caring nature, clinical training and expertise in cosmetic injections to achieve beautiful non-surgical results for our patients in a safe, comfortable setting.

Facial fillers coupled with laser treatments, topical products, and other special treatments have proven to reduce signs of aging and slow down the aging process altogether. It is a priority for us to stay up-to-date and current in today’s ever-changing aesthetic industry to help keep you looking young, fresh and natural.

The feedback from our patients about their experience with Kay’s injections has been phenomenal. She has a wonderful clinical eye for how to achieve a patient’s goals, excellent judgment and a “soft touch” in performing neurotoxin and filler injections. Patients have echoed these comments time and again, returning for repeat treatment at appropriate time intervals, as well as referring friends and family to Kay.

Although you can find Kay most of the time at work, she also enjoys spending time with her husband, Doug and twin sons, Gus and Lyle. As a family, they like to stay active, play board games together and take short trips in Doug’s Mooney airplane!
