The TEAM
Benny 🐾
Benny is our 2 year-old Cavapoo and the beloved pup of our office manager, Melanie. He’s quickly become the soul of our space. Affectionate, playful, and full of charm, Benny will welcome you with a wagging tail and maybe even his favorite toy. While he may not have an official therapy dog title, he’s everything you’d want in one—offering comfort, joy, and an occasional cuddle just when you need it most.
Feeling anxious or having a tough day? Benny's mission is simple: make you smile. Whether it’s a quick hello or a game of fetch, his presence adds a special kind of warmth to our practice. Come say hi to Benny—our official office greeter and unofficial mood booster. 🐾💛
Maggie🐾
“Dogtor” Maggie is an 8-year-old Lab/Beagle mix who belongs to Dr. Raman Gopalakrishnan. She’s the ultimate mellow girl—you’ll usually find her lounging around like a pro napper. But don’t let her calm nature fool you… she has a mischievous side too! Maggie’s favorite hobby is “borrowing” Benny’s toys and chewing them into oblivion. She’s also a big fan of tummy rubs, snacks, and spending her days by Dad’s side.
