  • Kristin Timpy MSN, APRN, AGPCNP-BC, IFMCP

    Kristin Timpy is a board-certified Adult-Geriatric Primary Care Nurse Practitioner with nearly two decades of experience in healthcare, specializing in family medicine, women’s health, cardiology, and functional medicine. She holds a Master of Science in Nursing from Monmouth University, where she specialized as an Adult-Geriatric Nurse Practitioner, and a Bachelor of Science in Nursing from Seton Hall University, graduating with honors. She also earned a Bachelor of Science in Biology with a specialization in Molecular Cell Physiology, receiving several academic honors, including the Sigma Xi Biological Honors Award.

    Kristin spent the first ten years of her career practicing cardiology in New York City and New Jersey before relocating to North Carolina in 2016. It was during this time, after navigating personal challenges with her daughter’s health, that she transitioned into integrative and functional medicine—a shift that ignited her passion for personalized, holistic healthcare. As an Institute of Functional Medicine Certified Provider, Kristin approaches each patient with a focus on addressing the root cause of illness, offering comprehensive care for conditions such as thyroid disease, gut health, autoimmune disease, diabetes management, cardiac risk stratification, and toxin exposure.

    On a personal note, Kristin lives with Celiac Disease and Hashimoto’s Disease—conditions she shares with one of her children. This personal health journey has profoundly shaped her approach to wellness, guiding how she cares for both her family and her patients. Married to her high school sweetheart, Kristin and her husband are raising three children and three dogs. In her free time, she enjoys paddleboarding, weightlifting, Pilates, yoga, and traveling, though much of her schedule is spent at youth travel ice hockey, volleyball, and soccer tournaments.

  • Holly Meehan RN, BSN

    Meet Holly, your certified nurse injector who has been working as a nurse in the field since graduating with her BSN in 2015. A North Carolina native, she began her career at UNC here in Chapel Hill as an RN in the orthopedic / trauma unit. She joins us from her latest role at UNC in Reconstructive Plastic Surgery, where she partnered with her surgeons to coordinate and conduct operative care for their patient populations, including breast cancer reconstruction, trauma reconstruction, and gender affirmation surgery.
    Holly loved getting to see and be a part of her patients regaining confidence in their bodies throughout their journey. "Feeling comfortable in your own skin is as big a part of healthcare as any other aspect; it touches the core of who you are as a person!" Entering the MedSpa world felt like a natural step in her career to foster her passion for helping people feel their best. Holly works closely with each of her clients on an individual basis to ensure that their goals and needs are being met.
    Outside of healthcare, she is bilingual, able to speak both English and Spanish. On a typical weekend, you can find her cooking, crafting, gardening, or reading with her two cats.

She looks forward to meeting and working with you!
