Veterinarians at Riverside Animal Hospital


Dan Drahos, DVM

Practice Owner, Veterinarian

More commonly referred to as simply “Dr. Dan”, he is a guy wearing many hats! A 1993 graduate of Iowa State University College of Veterinary Medicine, Dr. Dan has been the owner of Riverside Animal Hospital since 2001. Dr. Dan also serves as the President/Executive Director of the Animal Emergency Center of the Quad Cities which he was instrumental in opening back in 1999. To top it all off, Dr. Dan is the Program Director at the Muscatine Community College Veterinary Technician program where he has been teaching since 2010.

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. He has found it especially gratifying to see the positive affects our new therapy laser has had on his orthopedic surgical cases!

Dr. Dan, an avid cook at home, has been taking it on the road! His tail-gates at ISU football are legendary and he was crowned the Bar-B-Que Grand Champion at an ISU Grilling Competition! You may catch him at local BBQ competitions with his Two-Bohemians BBQ team. Dr. Dan decompresses by playing racquetball, golf, and gaming. A versatile musician and singer-songwriter, Dr. Dan has recorded several albums with his guitar and banjo and over 35 albums of European marches playing his flugelhorn and trumpet.

Practice Manager at Riverside Animal Hospital


Ken Drahos

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.
