I'm absolutely grateful for the amazing one-on-one swimming lessons at Longmont Athletic Club and so impressed with the coaching staff, especially Kellyn, for doing such a fantastic job teaching our son Eric! He's a challenging 13-year-old, but he listens to Coach Kellyn, which was a total game-changer! Definitely worth every penny, and we're now members – great facility and team! #SwimmingLessons #CoachKellyn #AthleticClub #Kids #Success

Private swim lessons for our daughter at the LAC were fantastic! She had a blast and greatly improved her swimming and confidence in the water in just a handful of lessons. Kellyn is a wonderful teacher and explains everything very clearly, while keeping it fun. She was also very flexible and we were able to meet exactly when it worked best for our schedule. Additionally, the staff at the LAC were always friendly and professional, greeting us every lesson. Highly recommended!

This gym has a lot to offer. It is older, and the machines and weights are older, but they still work. The steam room is out of order for men & women’s. They do have yoga classes for free with members which is really neat. I bought the 12 day pass to test this gym out. So far it’s great, just feels a little old and dirty on some machines and rooms. I do love the amount of things this gym offers, the only thing that would be cool to add, is a tanning bed or red light therapy. They require a six month membership which runs out $84, not bad at all. Also, my favorite machine is the stair stepper, and I did not find that in this gym );

My kids have been taking private lessons at LAC for a couple years now at the beginning of each season. Kellyn is the best swim teacher we have ever had! In just a couple half hour lessons both my kids feel completely comfortable in the water and are swimming great! I am so grateful we discovered this gem.

We love going to LAC! This is our first summer going to the club for swim lessons, and WOW! Kellyn is absolutely fantastic to work with! She is an excellent swim instructor and I feel so grateful that my kids have been able to do lessons with her! My kids look forward to seeing Kellyn every week :) she is very good with kids, and teaches the best fundamentals of swimming and also has fun with them! In addition to her great swim instruction, she is a joy to work with in terms of communicating and working with us and our schedule!! Thank you Kellyn and LAC for providing us with such a great swim lesson experience this summer 🥰 we will be back!
