Hi, I’m Coach Brittany!  I have worked with kids for the past 20 years whether it’s on the field or in the classroom.  I enjoy working at Cortiz Fitness because it allows me to make an impact on kids but in a fun and active environment.  My favorite sport to play is softball and my favorite sport to watch is hockey. I love watching kids grow into their full potential. When I’m not on the field working with kids I enjoy reading, going to the beach, or going on an adventure.

Hi, my name is Hunter and I am currently a student at UCF. I am from Cleveland, Ohio and moved here in August for school.
In Cleveland, I worked closely with children in the area of fitness. Originally I worked at an indoor trampoline park for 5 years supervising and having fun with kids of all ages, then I landed another job coaching gymnastics. My personal hobbies include running, biking, and hiking. I usually do one of these every morning to get my day started off on a good foot. Whenever I find time, I’m outside.

Working with Cortiz Fitness blends a lot of my favorite activities and allows me to incorporate those things into teaching and inspiring kids-a very rewarding way to end my day. Orlando is a wonderful city and I really enjoy working with the kids in the OCPS district.” .

Hunter currently coaches at West creek elementary, Stone Lakes elementary, East lake elementary and Baldwin park elementary.
