Mike Delliere, DVM

Veterinarian & Practice Owner

In 2010, Dr. Delliere received his DVM from St. George’s Veterinary School of Medicine. Having had many animals growing up, he decided to pursue veterinary medicine whilst traveling in South America for 6 months after finishing his first degree in Business Management and IT, in the UK.

Dr. Delliere enjoys all aspects of veterinary medicine, and is particularly interested in tick-borne diseases, endocrinology, soft tissue surgery and dentistry. He also derives great joy and satisfaction from treating animals and getting to know their owners. He and his wife, Willa, and their two children, Esme and Jasper, share their home with 3 pets: Lulu, a black Lab, and 2 cats named Peesh and Zebedee. When not at work, Dr. Delliere enjoys playing golf, skiing, and traveling with his family.

Gwen Hood, DVM

Associate Veterinarian

Dr. Hood has been passionate about caring for animals since childhood, but her path to becoming a veterinarian was not direct. In college, she earned her Bachelor’s degree in English Literature and Greek and Roman History. It was not until after she graduated that she decided to follow her dream of becoming a veterinarian, so she returned to college and spent the next 3 years completing her pre-vet classes. In 2011, she graduated as a DVM from Ross University.

For Dr. Hood, the most rewarding part of her career is creating close relationships with clients and their pets, and caring for pets through every stage of their life. She also enjoys cytology/pathology and geriatric care. She and her husband, Mark, have 2 daughters; Grace and Mabel. They also have 4 pets: Eva, a Lab/Weimaraner mix, Wally, a Schnauzer mix, and 2 cats, Georgia and Patty. Outside of work, Dr. Hood loves spending time with her family, reading, traveling, photography, painting and gardening.

Susan M. Tanner, DVM

Associate Veterinarian

Dr. Tanner obtained her DVM from Purdue University in 1984. Growing up in Indianapolis, she was fascinated with all kinds of animals, so it seemed only natural for her to go into veterinary medicine. She began her professional career in rural Minnesota at a mixed animal practice, eventually transitioning to equine medicine. Dr. Tanner later moved to New York state for equine practice, and opened Wood Hill Veterinary Clinic in 1994. In 2016, she sold the clinic to Dr. Mike Delliere.

For Dr. Tanner, the most rewarding part of being a veterinarian is successfully diagnosing and treating a patient, which in turn helps the humans involved. Her hobbies include riding horses, gardening, traveling, and walking her dogs. She also owns cats, horses, and goats!

Tyler Hotaling, VMD

Associate Veterinarian

Dr. Hotaling was raised on a small farm in Vermont. His mother was a hand spinner and used fiber from sheep and goats to make her handmade wool blend of yarn and other products. His step father raised (and still raises) pigs, Highland cattle, lamb, and chickens. Later, Dr. Hotaling’s family had a kennel of sled dogs that competed throughout the northeast in sprint races. Pets and livestock were a huge part of Dr. Hotaling’s early life.

He earned his Bachelor of Science degree in animal science from Cornell University in 2003, and obtained his DVM from the University of Pennsylvania in 2007. From 2007 to 2008, Dr. Hotaling completed an internship at Colorado State University Teaching Hospital. He also attended CE courses on anesthesia and pain management, dermatology, surgery, and dentistry. Prior to joining Wood Hill, Dr. Hotaling worked as a mixed animal practitioner in Colorado for 3 years, followed by 10 years at a small animal hospital in Albany. He has enjoyed developing close working relationships with pets, pet owners, and his coworkers at his previous practice, so he’s excited to do the same here at Wood Hill.

Dr. Hotaling, his wife, and their 2 children share their home and farm with a variety of animals, including: a geriatric Siamese-mix cat named Kuma; Toby, a Cattledog mix; Spotty, a Golden Retriever/Australian Shepherd mix; 20 chickens, and several Highland and Angus beef cows and calves. He also raises pigs and broiler chickens seasonally. His hobbies include trail running (you’ll often find him running through Hand Hollow Conservation Area on a summer evening), skiing, and working on his farm.


Hospital Manager

As a child, Corey always had a love for animals. She would always take her pets to the vet with her parents, and it was the highlight of her childhood. After school, she started cleaning kennels at the local vet, and worked at the dairy farm near her house. She has been at Wood Hill for 16 years, and enjoys building relationships with pets and their owners. Corey has a true passion for the veterinary world, and takes great pride in making clients and patients happy. Her favorite part of working at our animal hospital is all of the people she has met along the way, and the amazing people she gets to work with.

When not at work, Corey enjoys spending time outdoors with her family, and watching her son play sports. Her pets include French Bulldogs, a parrot, and a cat named Blossom.

Mary Ann

Licensed Veterinary Technician

Mary Ann obtained her AAS degree in Animal Science, and has been a Licensed Veterinary Technician (LVT) for over 30 years. She has always loved animals and medicine, along with getting to know people and their pets and making a difference in their lives. Her family includes her husband, Dan; their son Josh; Jackson, a German Wirehaired Pointer, and 2 retired Thoroughbred horses. Her favorite activities outside of work include hiking, kayaking, and rug hooking.


Licensed Veterinary Technician

Kimberley has always loved animals, and knew that she didn’t want to work behind a desk. At a young age, she began riding horses, and that fueled her love for animals. After graduating from high school she worked at horse barns in the area, and soon decided to attend State University of New York (SUNY) at Delhi for their veterinary technician program. In 2015, she earned her Associates degree in Veterinary Science Technology, along with her Veterinary Technician license.

Kimberley’s greatest accomplishment so far is graduating from SUNY Delhi and passing her licensing exam. Her favorite part of being an LVT is helping pets and their owners receive the best care possible. Her pet family includes a Terrier mix named Oliver, a cat named Buggy, an off-track Thoroughbred named Calvin and a few Betta fish. In her spare time, she enjoys walking Oliver and riding her horse.


Licensed Veterinary Technician

Liz drew a picture of what she wanted to do when she grew up at age five: in the picture, she was listening to a cat with a stethoscope. Her lifelong plan to work in veterinary medicine became reality when she obtained her degree in veterinary technology (A.A.S. SUNY Ulster, 2008). She subsequently obtained her license to practice as a veterinary technician (LVT). Liz also holds degrees in Equine Science (A.A.S. SUNY Morrisville, 2005), Animal Science (B.S. Cornell University, 2007), and Philosophy (M.A. Bowling Green State University, 2016). Liz pursued a graduate degree in philosophy because she was interested in animal ethics and ethical issues in veterinary medicine. She brings a focus on ethics to her everyday practice of veterinary medicine, and she is happy to work at a clinic dedicated to high quality patient care.

Liz lives with three cats that found her: Little, Zero, and Amici, and a Coonhound named Heironymous (Hero), who moved in when she married her husband Andy. In her free time she plays several instruments rather badly, studies wildlife rehabilitation, and is an avid birder.

To be able to work with and help animals was always the dream and she graduated from Mount Ida College with an associates in veterinary technology in 2018 and is now a licensed veterinary technician.

At home Lauren has 2 sweet calicos Chimera and Cleo, and a 6 year old betta fish named Stella. When not working Lauren enjoys reading, hiking, and horseback riding.



Kim is currently working towards her associates degree from Berkshire Community College. She has always had a passion for animals, and loves being able to help them in any way she can. Kim enjoys her time at Wood Hill working with our amazing team, and finds it very rewarding to help families with their fur babies and provide comfort and understanding when challenging situations arise. She has also met some really great people along the way!

Some of Kim’s hobbies include listening to her son play the drums, doing puzzles, crocheting, and, more recently, diamond painting. She is also a big fan of attending concerts and seeing local bands, and just listening to music in general.
