CrossFit Coaches



Ken Miller - Head Coach/Owner

  • CrossFit Level 2 Certified
  • Iron Athlete Weightlifting Certified

Ken started what is now known as CrossFit Tempe in 2013. He turned his weight around from close to 550 lbs, to 275 lbs. He was not on the “The Biggest Loser” or “Extreme Makeover: Weight Loss Edition” he did it all with CrossFit and Paleo. His success fueled him to get his Level 1 Cert and pay it forward by opening his own CrossFit affiliate. Ken is the heart of our box. His desire is to have everyone, no mater their fitness level (even no fitness level), shape or age achieve their fitness goals. It can be done, he proves it every day!


Armando Cruz - Head Coach

  • CrossFit Level 2 Certified
  • Pre & Postnatal Strength & Conditioning

My name is Armando Cruz but everyone at our box knows me as Cruz. I have been doing CrossFit for over 4 years now. I first met Ken at our first CrossFit box back in Mesa, AZ. Ken helped me get my CrossFit L1 back in 2013 and I have been coaching for Ken since then. I got my CrossFit L2 in September 2016 and Pre-and-Postnatal Strength and Condition certification in December 2016.

I am a full-time student currently attending ASU for my Bachelors in Exercise Science. I am currently Ken’s Head Coach/Manager and have been since early 2016. My main goal is to be an awesome coach before an athlete, seeing our community continue to grow and exceed in their fitness journeys are my favorite type of PRs. I am excited to see what the future holds for myself and CrossFit Tempe. I believe we have one of the best CrossFit communities in the Valley. Fitness for All.


Jenny Lewis

  • CrossFit Level 1 Certified
  • 200 Hour Certified Yoga Instructor

Jenny has been practicing yoga for seven years, originally discovering it as an alternative to weightlifting while pregnant. She started seeing improvements both in her mind and body as she continued to blend the two as part of her fitness routine. As a result of her love of both yoga and Crossfit, Jenny became a 200 hour certified yoga instructor and an L1 Crossfit Coach. She teaches both in hopes to help other people understand how these two very different activities compliment each other.


Zach Moran

  • CrossFit Level 3 Certified
  • CrossFit Endurance Certified
  • CrossFit Weightlifting Certified
  • CrossFit Kids Certified
  • BS Exercise Science 2013 & Biology 2014

I am Zachary Moran, a graduate from Sacred Heart University (Fairfield, CT) in 2014, where I competed as a division I wrestler and studied as a pre-med student. I started crossfitting in 2008 when introduced to it from a marine captain, but I have had experience lifting since high school athletics. After graduating from university, I turned my focus to coaching and competing as a crossfit athlete for the past 2 years. However, recently I have decided to further my education in medical school to become a naturopath doctor here in Arizona. I have a strong background in all aspects of the sport, including weightlifting, mobility, and programming, but most importantly I am extremely passionate for the athletes I coach.


Josh Crawford

  • CrossFit Level 2 Certified

Josh has an extensive athletic background spanning just about everything from motor sports to triathlons. He found CrossFit 8 years ago and has gone from using it as a tool for conditioning to being a level 2 coach. When he is not coaching at CFT, he loves spending time with his family and is an avid outdoorsman. His favorite WODs are Grace and Hotshots 19.


Cesar Samaniego

  • CrossFit Level 2 Certified
  • Freestyle Connection Advanced Course
  • CrossFit Scaling Certified
  • CrossFit Spot the Flaw Certified
  • BS Physical Education

My name is Cesar Samaniego. I graduated with a degree in Physical Education in Cuenca, Ecuador. I was a member of the National Kendo Team for Ecuador and competed in the 2015 Kendo World Championship in Tokyo, Japan. I started CrossFit in 2011, looking for good physical preparation for kendo, and I have been a Crossfit coach since 2012. I received my CrossFit L1 in Guayaquil, Ecuador, and then my CrossFit L2 in Bogota, Colombia 2016.

The best part of my job is being able to be a part of somebody's transformation...when they come into the gym and say "I'm never going to be able to do that" and then a couple of months later, I see them doing that exact thing! It's very rewarding and I love being a part of such amazing transformations.

Eric Rendon - Leader of the CrossFit Tempe Barbell Club

I’m Eric Rendon, I’m originally from Los Angeles and have been in Arizona since 2006 and graduated from Arizona State University in 2014. I became involved with CrossFit in early 2013 and I have loved it ever since. My interest in Olympic weightlifting increased during my time at ASU. During my final year of school I helped with the start up of the ASU Barbell Club. I enjoy spending time in the gym and spending time with my fiancé and our 2 kiddos. My favorite CrossFit moments are when I get to compete with friends. Competing with friends has been some of the best times I’ve had in CrossFit.
