Abby Deltano is 19 years old and has lived with type 1 diabetes for almost eight years. She first attended Friends for Life in 2018 and found really great people from day one. Ever since she was 11 years old, managing type 1 diabetes has been hard but hasn’t held her back from playing volleyball, figure skating, skiing, and doing absolutely whatever she wanted. It’s taught her a lot about how to overcome difficult situations, and Abby credits her my mom for so much of that. Abby also has a passion for writing, drawing, and anything she's able to create with her hands. She works as a full time veterinary assistant and loves coming home at the end of the day knowing she has helped somebody’s pet. Abby can’t wait to meet and see everybody again at FFL!

Someone once asked Mike Singletary, former NFL Chicago Bears linebacker, what his favorite part of the game was. He answered, "The opportunity to play." Since his diagnosis in 1995, Jimmy Dodson has expanded his classic athletic background into various areas of endurance and adventures sports for both the physical and mental challenges, as well as to demonstrate that diabetes is merely a factor that can be managed. Whether it is ice climbing, racing mountain bikes, running the Goofy Challenge, or playing a pick-up game, there aren't many things he has not tried. Over the years, he has been actively involved with CWD, Adventures for the Cure, Mountains for Active Diabetics, IDEA 2000, Insulindependence, Hope on 2 Wheels, JDRF Ride to Cure, and has experiences as a guide, coach, and fitness instructor.
