Ashley began at TGR taking fitness and pole before joining the front desk staff. She has been taking the 5:15am class regularly and competed in TGR Des Moines' very first Iowa Ninja Warrior competition. Ashley enjoys challenging herself with many of the classes offered at TGR. Teaching kids has become a passion and the ninja kids classes and parties are just the right fit. Seeing the kids conquer the challenges of the obstacles is very rewarding.

Ashley is married and has 3 very active kids that keep her busy both in- and outside the gym. Her husband Ben is a Medical Massage Practitioner, and she helps manage his business as well. She is currently working as a Special Education Associate with Ankeny Community Schools assisting mentally- and physically-challenged children as they learn alongside their peers.

Wendy Jensen

After seeing a deal on Living Social in 2012, Wendy decided to give TGR a try and has been attending classes ever since.

Wendy loves the environment and support at TGR and has increased her strength, flexibility and confidence with the continued encouragement from her TGR sisters.

Wendy holds a Piloxing Certification.

Bonnie loves working strength-based tricks and drops while practicing aerial. She has performed in local shows and events, and tries to participate in various workshop opportunities any chance she gets. When not training at TGR, Bonnie works for a local mental health provider. She also enjoys spending time with her family and dogs, and she has a strong passion for cooking up new dishes in the kitchen.

Proudly homeschooled, Jill started practicing aerial arts at TGR in 2012. Since joining, she has performed and competed in several events in the Des Moines and Chicago areas. She performs both as a solo act as well as half of the duo J.K. Rolling on silks, hoop, and hammock. Her favorite apparatus is aerial silks where she loves to work her Iron Cross and Secretary Drops.

Krystal Berger

A tumbler in her youth, Krystal has always loved to fly. She's studied aerial arts with TGR since 2014. Krystal trains primarily on silks and hammock but also loves trapeze, lyra and pole. She has performed with En L'Air Aerial Dance Co.; Cirque Wonderland; Little Mermaid Show: Daughters of the Air; and competed at the Aerial Expo and Aerialympics St. Louis. A stickler for safety and fun, Krystal's favorite part of taking classes and instructing is when someone discovers they can do what they previously thought impossible! When not at the gym, Krystal loves spending time with friends and family...and chasing adventure and chocolate.

Megan Assenmacher

Megan "Megan Loreen" has taken classes at TGR Fitness since 2013 starting with aerial silks and pole. She slowly transitioned to lyra and has since taken it as her main apparatus. Megan always loved having the opportunity to perform and the lyra was a wonderful addition to her already title-holding prop/auxiliary dancing. 

Megan has performed on lyra, hammock, and silks for 80/35, Misfit Cabaret, Aerial Expo, several TGR productions, performances as a member of En L’Air Aerial Dance Co., as well as other private events around Central Iowa.

Since then, she has gone on to perform with En L’Air Aerial Dance Company on hammock, silks, and pole as well as competing in 4 pole fitness competitions. Having no background in gymnastics—only some killer moves from high school show choir—she has had to challenge her mind and body in new ways, allowing her to be an even better instructor. In her aerial hammock class, she covers everything you'll need to get your feet off the floor: freestyling, increasing flexibility, strength moves, wraps and drops. Every class is a little different and she's always looking for new and exciting things to add to the curriculum. Sarah placed 3rd on pole and 1st on hammock in the Intermediate category at Aerialympics St. Louis 2018.

Sarah's other awards include 3rd place at CPC 2015 Level 2 Championship; and 3rd place at CPC 2017 Level 3 Championship.
