The Clinician 3 THE CLINICIAN SUMMER 2018 President’s Letter Dear Friends, It is my pleasure to be able to invite you to join us in Saratoga Springs, NY in September for our 10th Annual Symposium - From Our Practice to Yours. Having recently toured the town of Saratoga Springs and the facilities we will be utilizing, I can say with complete confidence that you will not be disappointed! Saratoga Springs is a beautiful place to visit, and the variety of restaurants, spas and shopping is astounding for a small town. The downtown is vivid, and is quite walkable from the hotels in the area, and just a short cab ride from the outlying hotels. Please consider booking an extra day to enjoy the town and all of its amenities. The Program Committee Chairs have assembled an all star line up of speakers from around the world to provide only the highest quality of continuing education available in both the classroom and wet lab settings. New this year we will be offering daily combined sessions to allow veterinarians and farriers to exchange ideas and information on certain topics, as well as various engaging topics specific to our lameness, podiatry, internal medicine and reproduction programs. I look forward to welcoming you to the Annual Symposium in person at our Welcome Reception at the National Museum of Racing and Hall of Fame. The board and myself are incredibly excited for this year’s Symposium and we hope you are too! See you in September, Dr. Travis Blackwelder President The Clinician 4 WE BELIEVE GREATNESS NEVER RESTS, AND ‘GOOD ENOUGH’ IS NOT AN OPTION.
