Dr. David Thomson, DVM
Chief of Staff, Surgery
Dr. David Thomson attended Harvard University, graduating in 1976. After spending a year as an assistant shepherd in Wales, he went south to attend the Tuskegee Institute School of Veterinary Medicine in Alabama, graduating in 1982. Following graduation, Dr. Thomson undertook a 14-month internship program at Rowley Memorial Animal Hospital/MSPCA in Springfield. He then stayed on as a staff doctor, taking care of a large caseload and being mentored in surgery by Dr. Joseph Stoyak.
In 1988, Dr. Thomson was accepted into the three-year residency program in surgery at the Veterinary Hospital of the University of Pennsylvania in Philadelphia. Following the successful completion of the program, Dr. Thomson returned to the MSPCA/Angell Memorial Animal Hospital West in Springfield, where he joined the staff as a surgeon.
In the fall of 1999, he and Ann McEwen opened Riverbend Animal Hospital. Initially, Dr. Thomson handled all the wellness care, medicine, and surgery cases. Since 2004, however, as the referral-surgery side of the practice grew, his work has been exclusively in surgery.
David lives in Northampton with his wife and a small gang of animals: Tiny Tim (pug), Jackson (golden retriever), and two cats (Louise and Clementine). They have two sons, Jamie and Mikey. In his free time, David loves to run, hike (especially in the Grand Canyon), travel, read, ski, canoe, and putter on the Connecticut River in his little Boston Whaler.

While in college, Dr. Burgess was an instructor in a laboratory section of the introductory biology class and a swimming instructor. She also worked as a regional hospital’s phlebotomist, blood bank, and medical lab technician.
After graduating, Dr. Burgess worked for the next seven years at the Nassau Veterinary Clinic, where she treated dairy cattle, horses, and small animals. She next worked at several small-animal hospitals in Pennsylvania, including a stint as a house-call veterinarian.
Peg moved to western Massachusetts in 2007 and lived on a mountaintop farm in Southampton with her husband and an assortment of pets and 4H ponies left by her college-aged children. Her interests include trail riding, snowboarding, and driving her favorite toy, a John Deere tractor.
Denise Reidy, DVM
Dr. Denise Reidy brings more than 15 years of experience in the veterinary field to our Wellness team, having worked in several practices and hospitals across Massachusetts. Focused on building close client relationships, she is dedicated to performing thorough workups of our patients to ensure their continued health and well-being. Alongside this commitment to providing quality care for her patients, Dr. Reidy is interested in dentistry and surgery.
A graduate of the Ross University School of Veterinary Medicine, Dr. Reidy completed her clinical rotation at Tufts Cummings School of Veterinary Medicine. Before attending veterinary medical school, she worked as an emergency/critical care veterinary technician. She also volunteered at the New England Aquarium in their rescue and rehabilitation program and at the St. Kitts Sea Turtle Association.
In her spare time, Denise enjoys hiking with her two dogs, Rey and Charlie, and her two human sons, watching movies with her cat, Lucy, reading, and keeping houseplants alive.
Lynn Candels, RN
Lynn came to work at Riverbend in 2005. “For as long as I can remember, I have loved animals. I am inspired every day by the relationship between them and their people. I am a registered nurse with a Bachelor of Science degree in nursing from Boston College, but I have found veterinary nursing to be the perfect celebration of the partnership. It is truly an honor to work with these creatures who teach us how to live fully and bring such joy to our lives.”
Lynn has spent the last 32 years working all areas of the veterinary field, “from wellness to emergencies…from the front desk, kennel, barn, and shelter to ICU and surgery…from dogs and cats to deer and dolphins…from nose to tail and from birth to death.” She is particularly interested in animal behavior, nutrition, and pet loss.
“Following the heartache of the losses of my beloved dogs and horse, our clients at Riverbend held me afloat with their kindness and the generosity of sharing their pets. For this, I am forever grateful. I am delighted to have adopted my next canine soul mate, sweet Izelle, a little Kentucky girl.”
Besides her love of animals, Lynn enjoys hiking, biking, adventures, good food, and music with family and friends.

Beverley, born and raised in England, had a passion for dogs and horses since she was young. She spent all her teenage years at the barn working with Show Jumpers, where she had a free loan horse named Valentine. After she graduated college, she entered the travel & tourism industry which took her on a diverse and incredible journey. She lived in various locations, including Ibiza, Spain, and Carnival Cruise ships throughout the Caribbean. Here she worked as a casino dealer who provided a lot of social and cultural experience.

This was when she decided she wished to pursue her childhood passion of working with animals. Her career in Animal Medicine began, and she spent 19 years working at Ludlow Animal Clinic. This exposure was a great way to kickstart her path and allowed her to gain a lot of knowledge in veterinary medicine. This opportunity also granted her experience in technician duties, front desk, accounting, assistance in surgical procedures, and inventory and practice management. Beverley joined the wellness team at Riverbend Animal Hospital in October 2020. She enjoys working with the incredibly professional, experienced staff: “I am so grateful to be working with such a wonderful team of Doctors and staff who truly care about the well-being of their patients and who practice such a high standard of medicine.”

After a long retail sales career, Sara switched to veterinary care and never looked back. In 2009, Sara started working as an adoption counselor at the Dakin Humane Society. From there, she took on a role in Dakin’s high-volume spay/neuter clinic. After intensive training at Humane Alliance in North Carolina, Sara became a veterinary assistant. Sara spent over seven years at Dakin learning every position in the clinic (except veterinarian!). Eventually, it was time for a change from the specialized environment of a spay/neuter clinic, and she ventured into private practice as a veterinary receptionist. Sara joined our Riverbend crew in April 2019; we love having her here. This is the perfect position for Sara, blending her love of animals, people, and science. Her spot behind the front desk at Riverbend is a dream come true! Working with a group of like-minded, compassionate people who love animals makes it a joy to go to work every day!
Sara enjoys making art, music, and bike riding when not answering the phones or snuggling animals at work. She lives at home with her son, a cattle dog mix named Rue, and a Chiweenie called Zoe.
Nancy joined us earlier this year when the pandemic started, and we needed extra help around the hospital. She helps with the phones, cleaning, running out to the cars, and giving an extra hand whenever and wherever needed!
Nancy is an artist who enjoys working with many mediums. Leaf collages are a specialty. She has worked at many places, including Glacier National Park, a backpacking store, the Vincent Smith Art Museum, a stained glass studio, and even on the Cape at a clam factory and a Bed and Breakfast.
At home, Nancy enjoys being creative with art and cooking, reading, walking, biking, and any activity that gets her outside in nature.
