Dr. Rainka started his college career as an engineer, but when a soccer injury left him in severe pain for over a year, he finally decided to see Dr. Day, a chiropractor, down the street from WPI, where he was attending college. No other healthcare professional, and he had seen many, had recommended chiropractic. Ironically, chiropractic was the only treatment that worked for him. After a few weeks his hip was better, and in one month the pain was gone. Dr. Rainka decided he wanted to help people the way Dr. Day had helped him. Dr. Rainka wanted to educate people about the benefits of chiropractic. He changed his major from engineering and graduated with a degree in biology from WPI.
