For almost 20 years, Kelley Hamill Lemay practiced as a Nurse Practitioner (NP) in Urology at DHMC. During that time, she treated many patients with vulvovaginal/genital disorders, all with the goal of increasing patient quality of life through appropriate diagnosis, research based treatment recommendations, partnership in healthcare, and empowerment of the patient in their medical journey. This exposure, and her own experience with an autoimmune/hypersensitivity reaction, led to greater interest in medical and cosmetic dermatologic conditions and procedures. Realizing this, Kelley joined the team at Peraza Dermatology Group and partners with patients to guide them through both medical and cosmetic experiences. Her current clinical interests include cosmetic dermatology, laser treatments, and medical dermatologic procedures, as well as how functional medicine may improve overall dermatologic health in the future.

Kelley graduated from the University of New Hampshire with a B.S. in Nursing. She practiced for three years as an RN at DHMC, on the Orthopaedics/Gynecology/Plastic Medical Specialties floor, then transitioned to Vascular/Transplant. In 2004, she graduated from Yale with her M.S.N/APRN degrees. Throughout her almost 20 years as an NP, Kelley served on many hospital wide committees and since joining Peraza Dermatology Group has led internal educational seminars, engaging staff, regardless of their position within the company, gain a better understanding of the services that are provided and the patients that we serve.

Outside of work, Kelley has been active with the Hanover Conservancy as a Board Member and committee Chair, as a Girls on the Run and Ford Sayre Nordic coach, and a Howe Library Corporation member amongst other affiliations in the Upper Valley. She loves to travel, to be in nature via hiking/skiing/doing yoga, and to spend time with friends and family. However, she is most content spending time with her husband and two daughters.
