The Fort Drum Team
Cali Marhevka | Instructor
Cali is certified in ISSA personal training and nutrition, and CPR/First Aid. She first took an interest in fitness and nutrition in college, when she noticed that her health was taking a toll on multiple aspects of her life. She began exercising and eating healthy and has never looked back. Cali discovered SLAM right before the delivery of her son. She officially joined wanting an outlet to get out of the house while enjoying her hobby in fitness. She realized she found something far greater, true friendship with like minded individuals. In Cali’s free time you can find her hiking, checking out a local coffee shop, or trying out a new recipe in the kitchen.
Mary Namestnik | Instructor
Mary is an ACE Certified Group Fitness Instructor and mother of three. She came to fitness during the COVID-19 pandemic when she started taking her children out for runs to fill their time while her husband was deployed. She ran her first half marathon in November of 2020 and never looked back. Her love of running has led her to run marathons and ultramarathons and it’s her desire to bring the sport to other mothers. Mary is also a doula, practicing birth and bereavement work in the area for mothers requiring her services.
