THE THRIVE STORY
Hi, I’m Katie Mullins, a board-certified Nurse Practitioner and the founder of Thrive Aesthetics in downtown Granville, Ohio. With over 10 years of nursing experience and five years as a Nurse Practitioner, my background has been rooted in providing compassionate, high-quality care in a variety of settings. I currently practice part-time in the emergency department, where I’ve developed a strong clinical foundation and a deep appreciation for patient-centered care. While I value my work in acute medicine, I felt called to explore a more personalized and restorative side of healthcare—one that focuses on confidence, wellness, and helping people feel like the best version of themselves. That passion led me to open Thrive Aesthetics three years ago, where I’ve been able to combine my medical expertise with an artistic eye and a genuine love for helping others look and feel their best.
At Thrive Aesthetics, I offer a comprehensive range of aesthetic and wellness services, including Botox, dermal fillers, Sculptra, microneedling, chemical peels, IPL and laser treatments, IV hydration therapy, vitamin injections, and weight loss treatments. My approach is always individualized—I take the time to listen, educate, and create customized treatment plans that align with each client’s unique goals. I am committed to delivering natural-looking results in a safe, comfortable, and welcoming environment. For me, aesthetics is not just about enhancing appearance—it’s about building confidence, promoting self-care, and creating a space where clients feel truly cared for. Whether you’re new to aesthetics or looking to maintain and refine your results, I’m honored to be part of your journey.
