Owner, Veterinarian
Limited practice at both Gap and Lancaster locations
Dr. Ashley Tuma grew up in Quarryville and obtained her bachelor’s degree in Zoology from University of Maryland, College Park. She attended Ross University on the island of St. Kitts for veterinary school and spent her senior year at the University of Illinois completing her DVM degree. Dr. Tuma has worked in several small animal clinics, mostly general practice, but has also done emergency medicine and worked for one of the largest no-kill shelters in the country.
She enjoys spending time with her husband and three young children doing anything outdoors; hiking, playgrounds, swimming and traveling to new places.
Medical Director at the Lancaster location, Partner Veterinarian
Dr. Jennifer Morris was born in New York City. She grew up in Summit, New Jersey. She attended the University of Pennsylvania, for college and veterinary school. Jen has lived and worked in southern NJ, Pittsburgh area, and now Lancaster county for the last 7 years.
Her main love is connections, both human and animal, that she makes in general practice. But she also loves emergency work as well and can sometimes be found picking up shifts at PETS in Lancaster.
She enjoys spending time in her garden with her herd of dogs, including 3 Great Danes. Her husband and two sons bring her constant comic relief.
She is one of the primary doctors at our Manor-Lancaster location but does serve at both our clinics.
Medical Director at the Gap Location
Dr. Cristina Walsh was born and raised in Nova Scotia, Canada. She completed her undergraduate studies at Cape Breton University in 2011 with a concentration in Biology. She then attended Atlantic Veterinary College in Prince Edward Island, Canada where she graduated in 2017 as a Doctor of Veterinary Medicine.
Following graduation, she relocated to Lancaster, PA. She has been practicing in the Lancaster area for the last four years.
Dr. Walsh shares her home with dogs, cats, a parrot, and a few reptiles. In her spare time she enjoys camping, riding motorcycles, and being on the water in any capacity.
Veterinarian, Practicing at the Gap location
While Dr. Riehl primarily identifies as a small animal general practitioner veterinarian, her true love has always been the less common companion pets referred to as “exotics”. She spent the majority of her free/elective time in veterinary school at Tufts working in the Zoological Companion Animal Medicine Department (ZCAM) and upon graduation was awarded the ZCAM Student of the Year award. Instead of pursuing exotic animal medicine as a board specialty, Dr. Riehl entered general practice veterinary medicine with the specific goal of returning to Lancaster, PA to provide mixed-animal veterinary services to the community that she grew up in.

Dr. Knox graduated from the University of Pennsylvania and went on to practice dairy cow medicine after school. Now as a small animal practitioner she loves preventative medicine, watching her puppy and kittens grow through life, and relieving foreign body obstructions through surgery. In her spare time she loves native plant gardening and even helped to update the flower beds at Manor Animal Hospital.

Veterinarian, Practicing at the Lancaster location
After graduation, I immersed myself in the fast-paced environment of emergency veterinary medicine for 7 fulfilling years. Eventually, I found my heart drawn to the warmth of family veterinary care, where I thrive in nurturing lasting bonds with both pets and their families. This duality has become my joy, and I’m dedicated to excelling in both arenas. I’m proud to be Fear Free (Level 3) certified and have recently added Reiki to my toolkit, witnessing its profound positive impact on my patients and their loved ones.
But my journey doesn’t stop there. I’m embarking on a new chapter in Integrative Medicine, exploring the ancient wisdom of acupuncture and traditional Chinese medicine to complement my Western training.
Outside the clinic, you’ll find me indulging in my creative passions, whether it’s painting, gardening, weaving, or experimenting in the kitchen. I’m also an avid gamer, with a soft spot for Mario and Zelda, and I’m currently mastering the art of crochet (left-handed challenges and all!). And what’s a day without a cup of Matcha tea or Chai in hand?
At home, I share my life with my wonderful fiancé and our adorable fur family: two dogs, Teensy and Holly, two cats, Bananas and Doug, and a flourishing collection of orchids.
Our family-friendly animal hospital serves dogs and cats, and helps educate their owners on how to help your “best furry friends” have a wonderful life with you!
