Dr. Valerius is originally from Hamilton OH. He obtained his undergraduate degree from Ohio Wesleyan University and his veterinary medicine degree from The Ohio State University. He has worked at small animal practices in both Grove City and Dublin and has returned to Grove City to open his very own practice!

He believes that all animals should have access to quality medicine, whether they have fur, feathers, or scales and sees a variety of different critters as patients. Dr. Valerius was mentored by Dr. Don Burton, founder of the Ohio Wildlife Center, and has been a volunteer at the wildlife hospital since 2007. His favorite animals to see are rats, opossums, cockatiels, and turtles.

Gabi co-founded All Critters with her husband, Dr. Valerius, after a long walk on an autumn afternoon. An Ohio Wesleyan University alumna, she graduated from The Ohio State University with a master’s degree in Veterinary Public Health.
