As the ancient Chinese proverb says, a journey of 1000 miles begins with the first step. My journey into healthcare began many years ago as a young man sitting in a doctor’s office wondering if I would live through my freshman year of high school. Now, many years later, I thank God for the lessons He taught me during that difficult period of my life and for the many lessons since. I don’t want to ruin the ending but I did survive my freshman year as well as the ones after and went on to the University of Florida where I received my bachelor’s in Nutritional Science and then my master’s in Nutrition and Dietetics and a minor in Exercise Science. During my time at the University of Florida I met my beautiful wife Adriane and she joined me on this adventure. For several years I worked as a clinical dietician at SHANDs and promoted the merits of preventive medicine. Seeing first hand, the medical needs of so many patients I decided to further my education by attending medical school at Midwestern University in Phoenix, Arizona. I was impressed by the Osteopathic tenants that promote the patient being a unit made of body, mind, and spirit and stating that we should treat all facets of the individual with equal emphasis. While in medical school I applied and was accepted for a prestigious scholarship that allowed me to continue my education and teach at the University simultaneously. During my time in Phoenix I was lucky enough to deliver both of my beautiful children Addison and Alexander who inspire me daily. The next step in my journey involved returning to my hometown in Orlando and completing the Family Medicine residency and integrated Fellowship in Neuromusculoskeletal medicine at Florida Hospital. During my final year as chief resident I learned about Direct Primary Care (DPC). Everything about DPC seemed to make sense of my entire journey. In this type of practice I could finally provide the kind of “whole-person” care I have always wanted and so was born Family Tree Primary Care.

Dr. Mahon - Primary Care Physician



When people ask me what I do for a living, I always answer, “I’m a husband and father who’s also a doctor” as opposed to “I’m a doctor with a family.” The most important parts of my life will always be my amazing wife and two beautiful sons. I guess my dogs are ok too.
I’m a local guy, been living in the Winter Park/Oviedo area since I was 2. Seminole County raised from Eastbrook Elementary, to Tuskawilla Middle and the Lake Howell class of 2000. I attended undergrad at UCF with a degree in molecular biology and microbiology, and received my medical degree at Nova Southeastern University in Fort Lauderdale, FL. I completed my Family Medicine residency at FL Hospital East Orlando. I also served as the Assistant Medical Director of the Community Care Clinic, a free clinic for the uninsured and impoverished. There I learned how to provide great care for the medically underserved on a shoestring budget.
When I grew up, I traded my Nintendo and Playstation controllers for saws and drills. I love playing around in the garage and have built nearly all the furniture in our house.
I’m beyond excited to have this opportunity to bring health and well-being to my hometown and take care of the people that have become my second family. This town raised me and now it’s time to give back!

Dr. Sparks Family Tree Primary Care




A Florida native, I grew up in Dunedin, Florida playing baseball and hockey with my brothers. After high school, I moved to the Orlando area to attend UCF for my undergraduate education where I received my Bachelor’s in Biology with a minor in Health Sciences. While at UCF I met my wonderful wife, an Oviedo native. I attended medical school at Ross University, where I graduated with high honors. While in medical school, I was active in the American Medical Student Association. I spent time working on projects related to conflicts of interest in medicine and medical education. It was during this time that I realized how Direct Primary Care would allow me to deliver the kind of medicine I wanted as a doctor. I completed my Family Medicine Residency at St. Vincent’s Medical Center in Jacksonville, Florida where I served as Chief Resident in my final year. While in residency I developed a passion for point of care ultrasound and its use in primary care visits. After residency, we knew it was time to come home to Oviedo to raise our family while giving back to our community and I’m super excited to be back. In my spare time I enjoy spending time with my young daughter, two dogs and watching soccer and hockey.
