About Alice
Dr. Alice Cohen founded RANDALI in 2001 on a simple idea: aesthetic medicine practiced with the rigor of a physician and the warmth of a long relationship. With decades of medical experience and a highly trained aesthetic eye, she built a reputation for results that are refined, natural, and grounded in lasting outcomes.
A licensed osteopathic physician who began her career in family medicine, Dr. Cohen became a trusted name in the Lancaster community, known for her commitment to precision, restraint, and clinical integrity.
Her approach to aesthetic medicine is rooted in a philosophy that puts health first, prioritizing skin quality, tissue integrity, and outcomes that age naturally over time. She believes aesthetic care should be personalized, measured, and grounded in medical expertise, with a focus on enhancing rather than altering natural features.
That philosophy remains the foundation of RANDALI today. The standards she set, and the team she built, continue to shape how the practice cares for every patient.
She opened RANDALI in 2001, and the standard she set is still the one every provider here works to.

Associate Clinical Director
Profile
Ask me aboutWhy restraint is the hardest skill in aesthetic medicine.
About Stephanie
Stephanie serves as Associate Clinical Director at RANDALI, where she brings a strong clinical foundation, advanced aesthetic expertise, and an approach to care centered on each patient. As a board certified nurse practitioner in adult and geriatric primary care, she combines her background in primary care and medical weight management with specialized training in aesthetic medicine to deliver thoughtful treatment plans focused on results.
Stephanie's work in aesthetics began more than two decades ago in plastic surgery. As a breast coach she guided patients through reconstructive and cosmetic procedures, from the first consultation through recovery, and she assisted in the operating room, including nipple reconstruction. That grounding in surgical anatomy, and in what patients actually go through, still shapes how she plans treatment today.
Stephanie is experienced in advanced injectable and biostimulatory treatments, with a focus on achieving natural, refined outcomes that align with each patient's unique anatomy and goals. Her clinical approach is rooted in precision, safety, and lasting skin health, ensuring patients feel confident, informed, and supported throughout their care.
In her leadership role, Stephanie plays an integral part in maintaining RANDALI's clinical standards, supporting provider development, and ensuring consistency across all patient experiences. She is known for her ability to balance clinical excellence with a personalized, approachable style of care.
Stephanie earned her Master of Science in Nursing from Wilkes University and holds board certification through the American Academy of Nurse Practitioners Certification Board. She is licensed as a Certified Registered Nurse Practitioner in Pennsylvania, Arizona, Delaware, and Utah, supporting care both in person and through telehealth.
She is an active member of the American Association of Nurse Practitioners and the International Society of Plastic and Aesthetic Nurses. Stephanie has also participated in international medical missions, supporting pediatric cleft lip and palate surgeries in underserved communities, reflecting her commitment to compassionate, impactful care beyond the practice setting.
She has joined international medical missions supporting pediatric cleft lip and palate surgeries in China, Honduras, and Ethiopia.
