Dr. Jana Layton, DVM

Riverbrook Animal Hospital was started by Dr. Robin Johnson in 1998. Dr. Layton started working at Riverbrook in June 2007 and purchased the practice from Dr. Johnson in March 2009. Dr. Layton considers it a true gift to have the opportunity to carry on the mission of Riverbrook Animal Hospital. The hospital will continue to strive for providing exceptional care, customer service and making a positive impact on all the lives the hospital comes in contact with. A commitment to continued education and training for the entire staff so they may provide the best veterinary medicine possible is a vision passed on by Dr. Johnson and embraced by Dr. Layton.

Dr. Layton was born in Tulsa and raised in Claremore, Oklahoma. She completed her undergraduate degree in biological science at the University of Tulsa in 1994. After spending a summer working on her dad’s farm, she decided to merge her love of animals and devotion to science into a career in veterinary medicine.
