Ashleigh Fowkes


Ashleigh Fowkes is an Associate Veterinarian at White Oak Veterinary Clinic. She attended Indiana University of Pennsylvania for her undergrad degree in Biology, and went on to complete her Doctorate of Veterinary Medicine from St. George's University School of Veterinary Medicine in June 2020. Dr. Fowkes also received her clinical training at The Ohio State University College of Veterinary Medicine and is Fear Free Certified. Her areas of professional interest include surgery, dermatology, dentistry, and internal medicine. Dr. Fowkes has been working in the veterinary industry since 2014 and says that becoming a veterinarian has been her dream as long as she can remember. Growing up, she always had a connection with animals, and couldn't dream of any other career to inspire her as much as veterinary medicine does.

Dr. Fowkes grew up in Apollo, PA and currently resides there with her four orange tabby cats: Scooter, Bijou, Mysa, and Pete. She rescued Scooter in 2015 who is paraplegic. When she is not providing quality veterinary care, she enjoys spending time with her family, boyfriend, friends, along with spending time outdoors traveling, kayaking, and hiking.

Stephen Treese


Dr. Stephen Treese is an Associate Veterinarian at White Oak Veterinary Clinic. Dr. Treese was inspired to become a veterinarian after helping with the Humane Society's rescue work shortly before and through Hurricane Katrina. He graduated with his Doctorate of Veterinary Medicine from the University of Missouri in 2015, and his areas of professional interest include oncology, diagnostic imaging, small mammals/exotic pets, reptiles, and birds.

Dr. Treese says the best part of working in the veterinary field is being able to improve and often extend the quality of life of an owner's best friend. Originally from New Orleans, LA, Dr. Treese currently lives in the northeast area of Pittsburgh with his wife, Amber, two dogs, five cats, and chickens (he also says his wife has too many reptiles to count!) In his free time, he enjoys doing yard work and playing sports. He also volunteers by helping wildlife rehabbers with medical needs. A fun fact about Dr. Treese is that he has trained permanently injured hawks and eagles for lives in captivity.

Megan Hayden

Practice Manager

Megan Hayden is the Practice Manager of White Oak Veterinary Clinic. She completed her Veterinary Technician Degree at the Median School of Allied Health School in 2000, and went onto complete an internship at White Oak where she was hired full time as a veterinary assistant. Megan's areas of professional interest include management and team building, along with providing quality care to animals and support to their owners. Her love and passion for animals inspired her to work in the veterinary field, as she grew up with horses, dogs, cats, and pocket pets. She says the best part of working in the veterinary field is helping those without a voice.

Megan has lived in Penn Township all her life, and shares a home with her husband, Ed, and two children, Henry and Hannah. She also cares for her four Australian Shepherds, Penny, Blue, Ollie, and OZ, two Ball Pythons, Jet and Rex, two ferrets, Sammy and Bendy, and a Bearded Dragon named Fruity. She says she has had many favorite breeds of cats and dogs, but is loving her "Aussie Posse" right now! When she is not practicing quality veterinary care, she enjoys walking her dogs at the lake and spending time with her family.

David Fleck, DVM

In Loving Memory

December 6, 1967 - May 13, 2019

The White Oak team remembers Dr. Fleck, who served as Medical Director for several years until his passing in May 2019. Dr. Fleck's calm, thoughtful, and caring nature is irreplaceable, and we feel lucky to have experienced it and learned from it, along with the example he set for going above and beyond for all of the pets that he treated throughout the years.

Dr. Fleck received his Bachelor's Degree in Biology from Indiana University of Pennsylvania and his Doctorate of Veterinary Medicine in 1994 from Ohio State University. Originally from Altoona, Pennsylvania, Dr. Fleck served clients and pets at White Oak Veterinary Clinic for over 11 years. His professional interests included internal medicine, complex surgeries, endoscopy, and more, and Dr. Fleck was recognized by all pet parents for his calming demeanor and attentive approach to medicine. Outside of the hospital, Dr. Fleck was dedicated to his family, rescued pets, and the great outdoors. His contributions to our hospital family and all those who knew him will not be forgotten.
