I adore and love being around children so to be able to be the Kids Club Coordinator at Core Athletic Club and seeing all the smiles just makes my day. I personally have 3 kids and 3 grandbabies, so I felt this position was perfect for me.

Wife, mom of two toddlers, and passionate member of the Core community! My journey with Core began when I became a stay-at-home mom and was looking for a gym with childcare. Fast forward to today, and I’m now managing Core’s social media and gym merchandise and loving every minute of the connections and support it brings. It’s been amazing to grow alongside such a positive, empowering community!

— Chandler R.
Core is simply the best! I'm a regular in their classes, and I can't get enough. The instructors are fantastic – always there to guide and motivate us. What I love most is the sense of community. And let's not forget how clean everything is – major bonus points!
— Marian B.
CORE is an incredible gym and community! The facility is always clean and the staff is extremely friendly! They are always eager to assist with any membership needs! Additionally, the personal trainer, Travis, is very knowledgeable and an expert when it comes to fitness and exercise! Would give them 10 stars if I could!
— Robert A.
What really sets Core Athletic Club apart is the community feel. Unlike some of the bigger gyms, this place has a small, tight-knit group of members who are all friendly and welcoming. The staff is incredibly knowledgeable and always willing to help you with your fitness routine or answer any questions.
