Meet the North Buffalo Animal Hospital team that will be your pet’s healthcare team helping you provide your pet the care to keep them healthy throughout their whole life.
Born and raised in Buffalo, New York, Dr. Stevens traces his roots back 150 years to an Attica dairy farm that his family still operates today.
After a ten year corporate career, Dr. Stevens returned to Cornell University to pursue a degree in Veterinary Medicine. He succeeded Dr. Frank Yartz at the Ellicott Street Animal Hospital as the sixth owner of this practice in 2006. How surprising to end up owning the same practice where he took his Brittany spaniel and cat as a youth!
Clinically, Dr. Stevens enjoys the wide range of health concerns presented through the dogs and cats the practice sees every day. He has developed a particular interest in dentistry, and the nutritional management of health and disease.
He is a past president of the Niagara Frontier Veterinary Association and the Buffalo Academy of Veterinary Medicine and chair of the Ethics board for Western New York Veterinary Association. He has helped rebuild the Frank A. McClelland Sr. veterinary hospital at the Buffalo Zoo and led the effort to create Western New York’s first dog park. He was very proud to receive, on behalf of the Hospital, the 2014 Buffalo Niagara Business Ethics Award.
He founded the first low-cost vet clinic in the region, The West Side Pet Clinic, to help ensure that the less fortunate could afford basic veterinary care for their pets.
Dr. Stevens and his wife, Carolyn Hoyt Stevens, have two daughters in addition to Ellie and Eberhard Lothar Faber III (a.k.a The Sauce).
Dr. David Gurzak was born and raised in Buffalo and attended SUNY Geneseo for his Bachelor’s Degree. He graduated from Cornell University College of Veterinary Medicine in 2012, and subsequently completed a year-long internship in Colorado. He worked in Buffalo for several years and then moved to Portland, Maine, but returned in 2018. Dr. Gurzak is a chairperson on the WNY Veterinary Medical Association board, and enjoys hiking, reading, biking and spending time with his family and friends. He and his husband Chad and their daughter and son live in the city of Buffalo with two cats named Beau and Magpie and a dog named Ernie.
After earning her undergraduate degree in Kinesiology and Business from Western University in 2017, Dr. Alyssa Kramer decided to take her career in a different direction and pursue her lifelong passion for animals and medicine. She went on to graduate from the Ontario Veterinary College in 2023 with her Doctor of Veterinary Medicine degree.
Dr. Kramer’s clinical interests include surgery, anesthesia and pain management, and community outreach. She is especially passionate about creating a collaborative, judgment-free environment where pet owners feel supported in making the best decisions for their pets in their unique situations.
Outside of the clinic, Dr. Kramer enjoys traveling, hiking, skiing, and fishing. Through her travels she’s proud to have landed a trophy-sized Northern Pike, Roosterfish, and Rainbow Trout. She also loves spending time with her dog, Tink — originally a foster fail, and now a thoroughly spoiled adventure buddy. In fact, Tink may even enjoy fishing more than Dr. Kramer.
Dr. Alexandra Hrapach was born in Ukraine and grew up just outside Toronto, Canada. She graduated with a Bachelor of Science degree in 2012 from the University of Guelph. Dr. Hrapach’s strong passion for animal care led her to obtain a veterinary medicine degree from St. George’s University in Grenada and complete her final clinical year at Cornell University. She enjoys all aspects of veterinary medicine with a special interest in dermatology.
Outside of the hospital, Dr. Hrapach likes to spend time with her family, friends and dog Charlie. She enjoys traveling, baking desserts and scuba diving in the Caribbean.
Dr. Kelsey Warner is originally from Erie, PA. She realized she wanted to be a veterinarian as a toddler, and has always kept that dream in mind in everything she has done. She worked at Wegmans for five years in high school and college, where she discovered her love of customer service and working on a team. She graduated from Edinboro University of Pennsylvania in 2020 with a Bachelor’s of Science in Biology, and a minor in Chemistry and Psychology. She graduated from Cornell University’s College of Veterinary Medicine in 2024. During her time at Cornell, she worked as a Customer Service Representative at the front desk of the Companion Animal Hospital.
Dr. Warner is very excited to be working in general practice as she loves working closely with owners to help pets live long, happy, and healthy lives! She is grateful for the opportunity to be a part of their lives from kitten and puppy examinations, to geriatric care and end-of-life support, and everything in between. Her special interests in veterinary medicine include feline medicine, internal medicine, and cardiology.
Outside of work, Dr. Warner lives with her partner and their two cats, Laria (pictured) and Chowder (although we don’t need a crystal ball to see more cats in her future). She enjoys theatre, performance, reading, board games, and watching movies and her favorite TV shows. She looks forward to being a part of a team with pet owners that will provide the best care to each pet on an individual basis through an environment of compassion and understanding.
Dr. Mya Marchiano began her veterinary journey at Medaille College in Buffalo, NY, where she became a licensed veterinary technician in 2020. She went on to complete her bachelor’s degree in biology in 2021. Before entering vet school, she worked as a technician for about a year and a half, gaining valuable hands-on experience in patient care.
Dr. Marchiano earned her Doctor of Veterinary Medicine from St. George’s University and completed her clinical training at The Ohio State University in 2025. She has particular interests in dermatology and internal medicine, but enjoys the full spectrum of general practice and the variety it brings to each day.
Outside of the clinic, she loves reading, spending time with family and friends (including her cavapoo, Winnie and orange tabby, Finnegan) and exploring new places through travel.
Dr. Shileyn Rego grew up in Rochester, NY, before attending Cornell University in 2008 to earn her bachelor’s degree in Animal Science. She continued at Cornell, completing her DVM degree at the College of Veterinary Medicine in 2012.
After graduation, she moved to the Buffalo area and has been practicing locally since. Dr. Rego has developed a special interest in preventative care, internal medicine, and feline health.
Outside of the hospital, Dr. Rego enjoys reading, traveling, and baking. She resides in Clarence with her husband, three kids, and two cats, Mango and Squirrel.
