Ashley Harris, BSN, RN

Nurse

Ashley is a registered nurse with a diverse and progressive background in healthcare, wellness, and aesthetic medicine. She earned her Bachelor of Science in Nursing from Nova Southeastern University in 2017 and began her career in telemetry before transitioning into outpatient cardiology. During this time, Ashley recognized a critical gap in traditional healthcare—an emphasis on managing chronic diseases rather than preventing them through education and lifestyle changes.

Driven by her passion for fitness, health, and holistic well-being, Ashley pursued opportunities beyond conventional clinical settings. She became the lead registered nurse at a functional wellness clinic, where she gained extensive experience in IV vitamin therapy, peptide treatments, and contrast therapies such as heat and cold exposure. This role deepened her understanding of preventative care and its powerful impact on long-term health.

Ashley later expanded her expertise by managing a hormone clinic and medspa in the Pittsburgh area. There, she developed a strong foundation in male and female hormone optimization, peptide therapy, and aesthetic medicine. Witnessing the transformative effects these treatments had—not only on patients’ physical health but also on their confidence, relationships, and overall quality of life—solidified her commitment to advancing a more proactive, patient-centered approach to medicine.

Continuously seeking growth, Ashley further refined her clinical skills in the operating room and in oral and maxillofacial surgery, strengthening her pathway into plastic and reconstructive care.

Today, Ashley brings together her comprehensive experience through her work with PCPS, where she is dedicated to helping patients look and feel their best while empowering them with the tools for lifelong wellness. She is passionate about delivering personalized care that bridges the gap between aesthetics, health, and preventative medicine.

Outside of her professional life, Ashley enjoys spending time with her husband, Bill, and their family and friends. She leads an active lifestyle, participating in running, hiking, weightlifting, and yoga. She also has a love for philosophy, healthy cooking, interior and architectural design, and travel, always seeking new experiences and inspiration.
