About the team

  • Mateo <span class="nick-name">"Wendigo"</span> Collazo
    Mateo "Wendigo" Collazo
    Hello, my name is Mateo and I am a husband and father of 5 kiddos which all keep me very busy. I am very honored to have been involved in all aspects of Combat Sports starting with boxing training from age 5 and competition by age 8. Wrestling in school from 5th grade through Sr High School along with submission grappling tournaments at age 15. I started training Karate at age 11 and earned my black belt at age 36. Muay Thai training and competition started at 16 with MMA added by late teens then finally capped off with an eighteen year career in both MMA and K-1 Kickboxing. My time on the mats has had me training alongside literally 1000’s of men and women both Pro competitors and average people with no desire to compete in a ring or get hit but want the incredible and empowering feeling that training like a “Fighter” offers. The hardest workers in the room, I have always found, are the ones not doing it for themselves but for their own lives, the people in their lives, and having an active lifestyle vs a sedentary one. No matter what you are looking to find whether it’s yourself or your hips again I know this is one of the best places for you to start that search!
  • Julie <span class="nick-name">"Jurassic"</span> Williams
    Julie "Jurassic" Williams
    My name is Julie Williams. I was born and raised in Highlands Ranch leaving for undergrad at CSU in Equine Science then to Australia and Asia for 2 years for missions work. After traveling and eating less healthy food, I needed to find a way to get back into shape. Finding 9Round, I discovered a fun and engaging way to workout, plus getting to punch and kick which is highly cathartic. I enjoyed going and the trainers were all awesome so when I was given the opportunity to join a few months ago I gladly joined the team
  • Peter <span class="nick-name">"Sweet P"</span> Renquist
    Peter "Sweet P" Renquist
    My name is Peter but I will answer to my fight name, "Sweet P". My journey is ongoing just like all the amazing members of 9Round. I have been a member of 9Round for almost 2 years and a trainer for 1 year. My likes include but are not limited to: long Round Kicks on the beach, various types of food, knock out compilations, live concerts, and creating my own noises on my laptop (making my own music). I look forward to seeing you in the gym motivating you in the very near future.

    Erahn "Buttercup" Martin
    I'm a mom of 2 boys (3 & 8 years) and I run my own business in the cannabis industry. Health and wellness have always been a passion of mine. I've spent the last year and a half spreading awareness on CBD, helping people improve their quality of life. I've always incorporate some type of fitness or exercise into my routine as well as a healthy diet. I am passionate about helping others reach their health and wellness goals, I take pride in watching transformations happen and help people feel better in their own skin! I can't wait to meet you and look forward to setting goals together starting with the 9Round workout!!
  • Cambrie <span class="nick-name">"C-Swizzle"</span> Vergeire
    Cambrie "C-Swizzle" Vergeire
    Hello, my name is Cambrie Vergeire! I was born in California, but I have spent most of my life growing up in the beautiful state of Colorado. I’ve been involved in many school and club sports such as swimming, track and field, cross country, competitive dance, and Karate. Fitness has always played an essential role in my life as I’ve struggled with some serious health problems. It has provided and still provides me with an escape from the worries and stresses of life, and I wouldn’t be who I am without it! At the beginning of 2018, I sustained a severe concussion during dance practice. Because of this, I was forced to quit midway through the season as the risk of further injury was too high if I were to finish. I didn’t participate in any sports from January to the summer, and I found myself not exercising and without a healthy outlet for my stress. Because of my background in martial arts, I decided to do some research and found 9Round! I dragged my family along to complete the free first-time workout, and we quickly fell in love with the workout and the trainers! The encouraging atmosphere and awesome results have kept me motivated, and I hope I can provide the same experience for you! I can’t wait to meet you and am excited to help you achieve your goals!!
