LISA - practice manager

LISA

practice manager

Lisa graduated from University of Central Florida with a Bachelor’s Degree in Hospitality Management. After working for Hotel Brands like the Peabody Hotel Group and Ritz Carlton, she decided to make the switch to working in the medical field in 2008, after a personal weight loss journey to better health changed her life. She has since managed several medical organizations in Orlando including a national weight loss company, a surgery center, and concierge medical practices. She loves taking her hospitality background and applying it to healthcare so she can give top notch customer service and care to patients, and break the system many are used to with rushed doctors appointments. She believes patients deserve better and is determined to give them an experience like walking into a Ritz Carlton when they walk in her office. Lisa is passionate about helping people live longer, fulfilling, happy lives and says it’s important to treat people like you would your own family.

In her spare time, Lisa loves spending time with her family and puppy, doing escape rooms, trying new restaurants, going to Disney and watching movies.

Giving them the peace of mind knowing that they have someone in their corner who cares and is looking out for them is what I care about.”
