On a Personal Note:

Dr. Gagné is a Professional Skier. He was a Level III Alpine Instructor and Level I certified Telemark Instructor. He is a graduate of Skip Barber Racing School in 2004, and holds a competition license. Training was in open wheel formula racers and he instructs with SCDA. His track car is a Lotus Evora.

While currently on hiatus from the sport, he is also an avid golfer with a 7 handicap (though doubtful he'd play to that at present!). The track has become much more exhilarating! In the summer.  He is an avid outdoorsman in the Maine mountains.

He has been married to his lovely wife, Susan for 27 years. He has 3 Toy Poodles and is their groomer. He is quite hands on and loves to take care of his property, cars, and other things around the house. He is passionate about the use of LASERS in dentistry.
