Your Longwood Managing Partner
Jeremy Avner
Jeremy Avner brings over 25 years of experience as a successful business owner and operator, with the past 15 years specializing in weight loss and hormone replacement therapy to the Nuviva team. With Jeremy’s passion for serving others and providing an understanding, and more importantly, a solution to people’s problems, he was a natural addition to Nuviva’s Corporate structure.
Like many of us, Jeremy battled obesity, gut issues, low testosterone, and was not getting the help and knowledge base he needed to take control of his health. Because of this need and his passion for helping others, Jeremy partnered with long-time friends, Alex Joseph and Jeffrey Delaney, to become one of Nuviva’s first franchise locations. He opened his first clinic in Orlando in 2011.
Jeremy states “I am extremely grateful to be able to share my passion, provide the tools to help others tap into their greatest potential, and guide them to become the absolute best version of themselves.”

Jessie Belanger
Growing up in a family with 6 kids, healthy, high quality food were not an attainable reality in Jessie’s upbringing. During college, Jessie pursued a degree in Health Science which led her to an internship at Nuviva Medical Weight Loss. While interning, Jessie learned a lot about health and nutrition and decided to try the program for herself. Through her success, she learned to change her perspective on food and became an avid supporter of the Nuviva program.
Through her personal upbringing and journey to better health, Jessie is able to relate to her clients and their struggles. She has empathy and understands what others face while working towards a healthier lifestyle. She is able to lead people to reaching their goals by changing their mentality towards and past relationships with food. Jessie truly cares about people and wants to help everyone become the best version of themselves.

Heather Meade
I moved to Orlando shortly after graduating college at East Carolina University. I have been part of the team at Nuviva since 2016, working at both the Orlando and Lake Mary locations. I greatly enjoy sharing my passion for health, wellness, and living a healthy lifestyle with our family of clients. I participated in several sports growing up, but most enjoyed the discipline and athletic skill required to advance competitive cheerleading. Even as an athlete, I experienced my own struggles with weight in the past and know what it takes to gain control of life’s choices necessary to make changes to live a life dedicated to being healthy. I look forward to helping you reach your goals by teaching you how to not only lose the weight but keep it off for good!
