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.

Dr. Rachael Baldwin, D.V.M.

Dr. Baldwin became a general practitioner at Riverbrook Animal Hospital in July 2020. Her journey to veterinary medicine began as a child who loved helping animals and was fascinated by animal behavior and the human-animal bond. Upon graduating with her undergraduate degree she began shadowing the veterinarians at Riverbrook Animal Hospital where she watched her first surgery and decided she wanted to become a veterinarian. She still feels that same sense of wonder when she takes on a difficult case and formulates a plan of diagnostic and treatment options, all with the goal of giving an animal a better quality of life.

Her passions lie in soft tissue surgery, pain management, animal behavior and Fear Free and Cat Friendly veterinary visits, and fostering the human-animal bond.

Dr. Baldwin received her Bachelor’s degree from The University of Tulsa and received her Doctorate of Veterinary Medicine from Oklahoma State University College of Veterinary Medicine in 2018 before accepting an internship in small animal medicine and surgery. Dr. Baldwin is a member of the American Veterinary Medical Association, American Association of Feline Practitioners, and is a Fear Free certified veterinarian.

When Dr. Baldwin is not in the office treating patients, she can be found traveling, hiking, playing with her beagle (Edie) pitbull (Gunner) and cats (River, Meadow, and Cat) and spending time with her family and friends.
