Stu Gertz
Stu was introduced to weightlifting at the age of 10 when his older brother received a weight set for his birthday… He fell in love with it from day one. He became a personal trainer in 1993 having already competed in multiple bodybuilding contests, the first of which was the 1991 AAU Mr. Bay State. As life took over with several business ventures he drifted in and out of the exercise lifestyle for several years while also battling weight issues. After some soul searching he vowed to get healthy and got back into personal training in 2005. He has been a National Academy of Sports Medicine Certified Personal Trainer since 2010.
Stu enjoys working with all ages and has extensive experience with the senior population, holding the prestigious NASM Senior Fitness Specialist Certification. He still competes in bodybuilding and is a nationally qualified athlete in the National Physique Committee(NPC).

Mandi Klimowicz
I love obstacle course racing, and when the gyms closed down in 2019, I was dragging my equipment (and my dog) outdoors to workout. People took notice, asked when I could train them, and my second career began (I also teach middle school full time). I became a certified personal trainer in 2020.
I connected with Milestone after the gyms opened back up and found the perfect fit! There, I work both as a group fitness instructor and personal trainer. In the group training environment, I like to challenge individuals with modifications that are appropriate to their body's abilities, giving them a workout they can be proud of. When it comes to personal training, I like to work with my clients to develop attainable goals and provide workouts they enjoy and look forward to. Fitness makes me happy, and I love being able to share that with others!
Kiana DelViscovo
Hi, I am Kiana, I grew up dancing and started lifting weights when I was in highschool. After graduating highschool I had hip surgery and started to focus on rehab and increasing strength. I fell in love with training, fitness, and how it changed my life, and I wanted to help others change their lives too. I got a four year degree in Exercise Science from Endicott College, and during my time there I interned with the Strength and Conditioning Coaches for the Boston Bruins! During the warmer months I enjoy spending time outdoors; hiking and going to the beach are my two favorite activities.
