Dr. Bast is what you would hope that all med students wish to be when they graduate. He is kind, caring and will do anything to make sure his patients are 100% taken care of. He is always willing to help others in need, in or out of the office. Our whole family has gone to Dr. Bast over the years and every time we are blown away by his bedside manner and kindness. There are not enough words to express our gratitude. Thank you Dr. Bast for everything..

Hello, my name is Rosemary and Dr. Bast had did two knee surgerys for me, believe it or not, 10 years ago! PCL and then ACL reconstructive surgery. At the time I had just been in a horrible car accident and was trying to recover both physically and mentally. Now 10 years later, I look and feel on every level, way better than I've ever felt before. I wanted to be able to Tell Dr. Bast thank you so very much for being a wonderful and exellent doctor. My knee is still doing great, thanks to You!!
