Dina is a lifelong sports enthusiast and the proud owner of Fitness Together Lynnfield, a private personal training studio offering one-on-one fitness and wellness coaching. Before launching her 20+ year career as a personal trainer, she struggled with weight and chronic back pain—barriers that kept her from enjoying an active lifestyle. After earning her B.S. in Sports Medicine from Sacred Heart University, Dina developed a personalized fitness plan grounded in kinesiology. She lost 60 pounds, reduced pain, and built the foundation for the coaching approach she uses today. Dina specializes in helping adults who feel like they’ve “tried everything” but haven’t found lasting success. Whether the goal is weight loss, strength training, or simply moving better, she focuses on sustainable routines that meet clients where they are. Together with her team, Dina has helped more than 1,000 clients transform their health—without fads or quick fixes.

When she’s not coaching or managing Fitness Together Lynnfield, Dina enjoys time with family, traveling to sunny places, and her favorite pursuit is golf. What began as a hobby is now an obsession. She loves exploring how mobility, core strength, and rotation impact the swing, and finds joy in applying movement science to improve her game on and off the course.Gina, Manager, Professional Personal Trainer

Gina’s fitness journey began with dance. A competitive dancer by age 12, she went on to study at Dean College, where she fell in love with expressing emotion through movement and helping others do the same. She taught at NRG Dance Center and Phunk Phenomenon before discovering how strength and mobility training could elevate both dance performance and everyday function. That insight sparked her transition into personal training, where Gina now blends creativity with functional fitness to help clients improve strength, flexibility, and confidence. She’s passionate about tailoring workouts for each individual and believes that movement should be empowering, not intimidating. As part of the Fitness Together Lynnfield team, Gina supports clients of all levels in building sustainable habits and achieving their health goals through one-on-one training in a private, supportive setting.

Becoming a personal trainer was an easy decision for TJ. Sports were always a big part of his life—from growing up to playing through college—and fitness just stuck. After college, the rest was history. Years later, he's helped countless people improve their health, build strength, and feel better in their bodies. TJ believes the best fitness routine is one you can follow consistently—even when life throws a curveball. Everyone’s got the same 24 hours in a day, and taking care of yourself shouldn’t feel like a burden. That’s why he focuses on creating simple, sustainable workout plans that fit your lifestyle and actually stick. He’s always been fascinated by how different everyone’s fitness goals and needs are. Whether you're working on weight loss, strength training, or just getting moving again, TJ’s goal is to keep the process clear, effective, and maybe even fun (yes, fun). Because working hard and enjoying the process shouldn’t be mutually exclusive.

When he’s not training clients or lifting something heavy himself, TJ’s working on his own fitness journey. Though he’ll admit he’s way more comfortable with a barbell in hand than out hiking in the woods. A proud Boston sports fanatic, TJ rarely misses a Patriots game (especially in the fall), and loves catching games live when he can. He’s also a self-proclaimed TV junkie. Whether it's Law & Order, a binge-worthy Netflix series, or whatever’s trending next. TJ’s downtime usually includes hanging out with his dog and trying (with mixed results) to resist the siren call of a cold brew from Dunkin’ or burritos from Anna’s, Chipotle, or really anywhere that serves decent Mexican food. He also considers it a personal win any time he walks past a sneaker drop without adding to his growing Air Jordan collection.
