Centennial CrossFit is a top-notch CrossFit box. It takes more than running workouts to make a great box, and Centennial has all that you could ask for. It all starts with the owner/operator, Lori Summers. She has a gift for identifying what's holding you back or what's keeping you from reaching a goal you're striving for (not just in the physical realm but also mentally & emotionally) and she's adept at working with you to break through barriers and overcome impediments. Her approach is absolutely personal, and she is never "too busy" to talk with you or help you. The coaches she has brought in to the box have their own styles, but that commitment to personalized and insightful coaching for each client is something they all have in common. Lori is also committed to bringing the best possible training events and opportunities to the Centennial community, so there's always something going on, whether it's a multi-week challenge, a competitive event, or a skill-development workshop. There are a variety of classes available throughout the day (including Ladies Only, which not many gyms offer) so you can always get a good workout in no matter what your schedule is. It doesn't matter whether you're a top-level competitive athlete or a former couch potato wanting to get in shape, you'll find excellent coaching, personal support and a terrific community at Centennial CrossFit. read more

I came upon Centennial Crossfit (CCF) by mistake and so thankful I did! My son is a big CF athlete so I was rather curious when I saw CCF on Facebook offering a "free" 6 week challenge for ladies! Somehow my finger entered my information and clicked the submit button! I was not sure if I would ever hear back from anyone but within minutes Lori Summers responded with a time and date for us to meet to discuss the challenge! From that point on the rest is history... I signed on the dotted line and my challenge was to lose at least 5% body fat in 6 weeks, understand I have been somewhat of a gym goer for years with some results but not drastic ones and me being a flight attendant just added more obstacles to my eating and gym habits.. I wasn't even sure if this challenge was realistic in 6 weeks but with me being a pretty competitive person, I remember telling my family to bring the challenge on! Long story short: Classes were unique/different and upbeat! Instructors were amazing and always available! Recipe book was easy to follow, included many yummy dishes! Did I win my challenge???? Yes I did and I actually exceeded the 5% body fat loss needed to win. If asked would I recommend CCF, my answer would be absolutely!! Thank you Lori and Jess for pushing me beyond my comfortable levels and making me accountable! You are the best!!! read more

****BEWARE**** WORST FRAUD GYM IN THE TOWN!!!!! I had extreme bad experience with Centennial Crossfit CCF, they trick me up to signup for 6 week "FREE" Challenge using FB promotion which is not free technically they asked for $400 and said once you complete 6 week challenge for "ANY" Body Transformation you achieve you will get your money refunded back!! That was all FAKE and a BIG LIE!!!!! After completing 6 weeks I had lost commendable amount of weight and body fat, but as soon I asked for my refund Lori Summers (the owner) said we will not return the money in any case as you have not met 6 week challenge and took my $400. She said the only option I can provide is to convert this money into yearly membership which would have me pay $100/month in addition to $400 they already have taken. Thats highest degree fraudulent scheme Centennial Crossfit CCF is running to steal wealth from people.I got seriously trapped into there FAKE promotion and lost my $400 dollars!! Please DONOT go to this gym or sign up for there any 6 Week Free Challenge promotions.. read more

Centennial CrossFit is a fabulous place to get back into shape! I couldn't believe how weak I had become and Lori took me under her wing (along with the other trainers) and showed me how to complete the 6-week challenge. I was a complete dunce and had no coordination/balance to speak of regarding any of the moves. Let me just state that every class is different and I love that!!! Everyone, including the members, is always willing to help and regularly give me advice so that I can be a better me, a stronger me. I joined to get fit, lose​ some weight and to learn how to become stronger. Each week I can see the difference! Thank you Lori (and your team!)! I would recommend this gym to anyone! read more

My wife joined CCF "new you" program in January 2017,she absolutely loves it. I reluctantly joined in June 2017 after ACL surgery to help with recovery. A year later I can't recommend Lori and the rest of the coaches enough. It's a great workout environment with amazing people. I have never felt fitter or stronger and with the guidance of the coaches my knee feels great. I've gladly signed up again for another year. The only down side to CCF is that I've had to tell my wife she was right. read more

You really won't find a gym that is more Community oriented and coaches that are more safety conscious. I've been going here for three years and worked beside all skill levels and felt safe and comfortable to push myself and also fail with out fear. I can't ask any question I want and never feel like I'm a nuisance. For someone who feared group fitness ... I'm never going back to normal gym life. read more
