Interested in all aspects of veterinary medicine, Dr. Dan does have a special interest in orthopedic and soft tissue surgery, laser applications for surgery and healing, plus current and new medication and medical techniques.

Ken Drahos

Practice Manager

Ken joined the Riverside staff in 2016. He recently retired from a 30-yr career working in the credit union industry. Working in all areas of banking, he spent the latter part of his career working in operations and process management. We are pleased to have his wealth of experience to assist in managing the financial side of our practice.

If the name sounds familiar, it is. Ken and Dr. Dan are cousins. In fact they are double cousins, as their mothers married their fathers. He is very excited to assist behind the scenes to enable Riverside staff to devote more time to their clients.

In his spare time, Ken loves to be on his bicycle. If the sun is out, the wind is down, and the trails are clear: even a winter day won’t keep him inside. He is also an avid bowler, with nine career 300 games and 22 (and counting) national tournaments under his belt.
