During his time at SDSU, Dan Marquette sought out any opportunity he could to get involved in his chosen field. One of these opportunities came from The Orthopedics and Sports Medicine Lab where Dan assisted Dr. Weidauer in the collection of data from over 100 athletes. Dan was primarily responsible for performing isokinetic testing of the hamstrings and quadriceps but Dr. Weidauer said that Dan could pretty much do anything he asked him to do. After graduation, Dan was accepted into the Gatorade Sports Nutrition fellowship program at the UFC Performance Institute in Las Vegas, NV. He was one of 10 applicants that were selected following an intensive interview and selection process. Dr. Weidauer said, “I am very proud of Dan and believe he will achieve anything he desires in his career. He has always and will continue to go above in beyond in pursuit of his goals."
