Our Team

We EMPOWER our members to take control of their health and get results that last.

Rob Gutierrez - Co-Owner & Coach

I’ve always been interested in fitness but it wasn’t until I needed it (my health was at risk) that I decided to put my words into action. CrossFit helped me not only get in shape, but it changed my life.  Some people go through life saying, “I can’t” and I hate that. When I’m presented with challenges I always ask, “What would it take to make this possible?” My goal is to help others do the same.

Diana Jimenez - Co-Owner & Coach

I wasn’t an athlete growing up. CrossFit was my first real experience inside of a gym that wasn’t cardio or a Boot Camp class. When I learned to move my body properly and lift weights I not only got amazing results, but I felt EMPOWERED by what I was able to do. I love making beginners feel welcome and at ease about their fears of CrossFit. As a coach, it’s my job to motivate and bring out more than they ever thought possible for themselves. It will be hard at first but in the end, it’ll be worth it!

Tommy Ziegen - Coach

My dream was to be a professional baseball player. After facing many challenges I finally achieved my goal. My passion for coaching grew as I left baseball and CrossFit was the perfect fit for me to guide athletes to chase their dreams. I hope to be a leader and a positive example for all athletes.

If I can describe the philosophy of RADD in a few words it would be, "You can do it!" This may sound like a common... phrase, but RADD lives by this philosophy from workouts, to eating, to lifestyle changes, and to overall mental and emotional health. RADD cares about the WHOLE person and helps you to achieve your goals. They treat you like family and they care about their people. Every coach works with you at your own pace and caters workouts to what you can do, and then pushes you to your next level. At first a CrossFit workout seemed like an impossibility to me but I once I took the plunge, I loved it because RADD made me feel that I can do it. Since every workout is structured to your abilities and what challenges you, everyone feels welcome in group settings and everyone supports each other. The RADD family helped me to become a better me both inside and out!read more

I recently joined RADD after moving from the city to Glen Cove, and so far the experience has been great! The owners... and staff have been incredibly welcoming, from the moment I requested information Dan reached out to me immediately (like, within a minute of pressing submit) and wanted to learn about my goals as well as what drives me to be fit and healthy. Since it’s a family run business, there’s definitely a personal touch you sense right away, they care a lot about their members and the quality of the space and equipment. With Covid, the safety measures in place have made me feel comfortable, and I’ve really enjoyed the workouts so far. The programming is well balanced and thought out, and it’s been great to help me get back in shape after quarantine. Everyone is super friendly and accommodating, I highly recommend RADD to anyone passing through the area or looking for a new CrossFit gym or fitness more
