Dr. Anderson
Veterinarian
Dr. Anderson grew up in Derry, New Hampshire, and has been practicing veterinary medicine for more than a decade. From a young age, he knew he wanted to work with animals and couldn’t imagine being behind a desk all day. Veterinary medicine offered the perfect blend of science, problem-solving, and the chance to make a difference in the lives of pets and their families.
At home, Dr. Anderson shares his life with a lovable dog named Charlie, a curious cat named Daisy, and dreams of someday adding an alpaca to the mix. Outside the clinic, you’ll likely find him hiking the trails of New Hampshire, jamming with friends, dabbling in woodworking or surfing, and soaking up all the outdoor adventures his home state has to offer.
Alexis
Hospital Manager
With Cornerstone Since: October 2017
Alexis, a lifelong resident of Epping, NH, has always felt a deep connection to the community where she grew up, the same town that is home to our veterinary clinic. Her professional journey in animal care began at a doggy daycare, one of her first real jobs. Seeking a faster-paced environment and more opportunities for learning, Alexis joined Cornerstone as a receptionist. Her dedication and passion for veterinary medicine led her to become the clinic manager within four years. Over time, Alexis has gained experience in every position at the veterinary hospital, demonstrating her versatility and commitment.
Drawn to veterinary medicine by her love for fostering healthy human-animal bonds, Alexis found her calling at Cornerstone. She has always been passionate about caring for animals and appreciates the small-town, family-oriented atmosphere of the clinic. Alexis is a familiar face throughout the hospital, whether she's assisting clients and patients up front, answering phones, working in exam rooms and surgery, or even out on the road.
At home, Alexis is a proud pet parent to two bearded dragons and four dogs. Outside of work, she enjoys spending quality time with her family, fiancé, and dogs. Her hobbies include camping, horseback riding, and cooking, all of which reflect her love for the outdoors and family-oriented activities.
Linda
Receptionist
Linda joined Cornerstone in October 2024, bringing with her a unique background in science and animal care. She grew up in Manchester, NH, where her father was a veterinarian for 35 years. Throughout high school and summers in college, she worked alongside him, sparking her lifelong love of veterinary medicine.
Linda earned her degree in medical technology and worked at Concord Hospital’s microbiology lab for five years before spending 30 years at the NH State Police Forensic Lab. At Cornerstone, she combines her love for animals with her science background. Linda shares her home with Craig, her 12-year-old “grand-kitty.” Outside of work, she enjoys reading, hiking, kayaking, and yardwork.
Find her upfront and trying to sneak into the lab around answering phones and helping clients.
Lisa
Receptionist
Lisa Flanders joined Cornerstone in 2025, bringing her passion for animals back into focus after several years in human medical billing and scheduling. She first began working in a small animal hospital in 2012 and quickly discovered how much she enjoyed being part of veterinary care. Although she later shifted into human medicine, Lisa missed working with pets and their families—which is what led her back to animal practice.
Growing up on a small farm in Seabrook, NH, Lisa has always had a love for animals and a strong interest in helping them live healthy lives. She’s also a proud “grand-pet parent” to two Brittanys, Remmy and Fig.
Outside of work, Lisa enjoys camping, boating, going to the beach, spending time with her granddaughter Indy, watching horse harness racing, and cooking.
You can find Lisa up front, helping patients and answering phones with a warm smile.
Alexa
Tech Assistant
Alexa joined Cornerstone in 2025 and brings with her a wide range of veterinary experience. Originally from the Southern Maine Seacoast area, she began working at a kennel before moving into a role at a local general practice. Her desire to expand her knowledge led her to Portland Veterinary Emergency and Specialty Care, where she gained valuable experience in the surgical and ER departments. While she enjoyed the fast-paced setting, she missed building long-term client relationships, which brought her to Cornerstone.
At home, she has two dogs: Frankie, her sweet 7-year-old Mastiff, and Oscar, a lively 2-year-old rescue from Georgia. In her free time, she enjoys chasing sunsets, spending time with friends, and enjoying good food.
