Tim Blackstone

General Manager / CrossFit Trainer

  • CrossFit Level 1 
  • US Army Veteran (1999-2006)
  • Black Belt in Brazilian Jiu-Jitsu

Tim was first introduced to CrossFit in 2005 while severing in the Army. “It was truly like nothing I had ever done before. I remember thinking ‘Man I thought I was in good shape’, I was hooked”.
So in 2007, after getting out of the Army in 2007, Tim sought out a new challenge with Brazilian Jiu-Jitsu (BJJ)—something else that he had been exposed during his Army Combatives School training. It was this confluence of need and location that brought Tim to start training BJJ and CrossFit with Damian Hirtz at a gym that was close to his hometown.
Eventually Tim completed the CrossFit Level 1 course and began coaching and programming for CrossFit Edina. Tim most appreciates that CrossFit poses specific challenges each and every day; however he believes that the biggest challenge is mental. “Helping individuals overcome the mental challenge of CrossFit is one of the greatest satisfactions I get as a coach.”

  • CrossFit Level 1
  • CrossFit Level 2 Trainer (CF-L2)
  • USAW Level 1 Coach
  • USA Swimming Coach
  • Red Cross First Aid and CPR

Lisa’s athletic specialty has always been not-specializing. As a kid, she played competitive tennis, basketball, and ran track, sometimes all in the same season. When made to choose a sport in college, she joined the University of Illinois Women’s Track and Field team and “specialized” in the heptathlon. Out in the real world, keeping true to her multi-sport nature, Lisa was drawn to triathlon. So in 2010 when Lisa stumbled onto CrossFit – with all its jumping, squatting, pushing, pressing, running, climbing – she was instantly hooked.
Now as a CrossFit trainer, Lisa enjoys making CrossFit accessible to people from all athletic backgrounds and fitness levels. She loves to see the physical, mental, and social transformations that happen in other people when they find fitness. In addition to training folks at CrossFit, Lisa designs and conducts dryland training for competitive youth swimmers. She is forever the student of nutrition, and spends much of her free time engrossed in nutrition research articles, especially those related to athletic performance, and trying out healthy recipes on her three teenage daughters and loving husband!

Alex feels a strong commitment to sharing what he’s learned over the years with other people who want to improve the quality of their lives by improving the health and fitness of their body. “Whether it is refining an Olympic lift, shooting for a PR, or just improving overall fitness, I love helping people reach their goals.”

George was once called a “jack of all trades” by his high school track coach…and that was before he tried rock climbing, kayaking, windsurfing, volleyball, rowing, taekwondo, hang gliding, yoga, and ballroom dancing. In fact it was the need to get stronger for his ballroom dancing that lead George to find CrossFit. “Finding CrossFit in my early forties was nothing short of miraculous…it has taught me so much about what is possible”. With that passion for pushing his own limits, George is always focused on coaching others to develop good technique and to encourage them to go beyond their self-imposed limits. In addition to being a strong motivator, George likes to introduce new movements and skill transfer exercises with the goal of keeping every WOD both challenging and rewarding.



Rob Evans

CrossFit Trainer

  • CrossFit Level 1 Certified 
  • CrossFit Level 2 Trainer (CF-L2)
  • 1st Place, CrossFit Tampa Next Level Fitness Challenge
  • BSB – Marketing and Entrepreneurial Management from the University of Minnesota
  • Doctorate in Physical Therapy from the University of Minnesota

What can you say about a guy like Rob? Well, he enjoys a low-round of golf, a middle-of-the-road comedy, and a high-intensity workout! That’s where CrossFit comes in. After spending years doing the typical globogym routine, Rob was searching for something more thrilling and engaging than simply lifting with an iPod on. In the spring of 2011, Rob stumbled into CrossFit Edina, and his life has never been the same. “I had no idea how many weaknesses I had in my fitness until I started CrossFit. Each day, I continue to get a little better, and that day-to-day improvement is what makes CrossFit challenging, rewarding, but most importantly…FUN!”
Upon graduating from college, Rob spent a year working down in Tampa, FL where he continued his CrossFit training. In January 2012, he entered and took 1st place in the scaled division of The Next Level Fitness Challenge, hosted by CrossFit Tampa. Although he hasn’t competed since then, Rob is eyeing a possible return to competition sometime in the near future.
As a coach, Rob provides a very encouraging and uplifting atmosphere for his athletes. “My number one concern while coaching is to make sure that everyone has solid technique and form, no matter what the movement is. Additionally, I try to make each class as fun as possible for the athletes, because if CrossFit isn’t fun, then people won’t do it!”
