Our Coaches

Mike Minium



My coaching career started when I was only 14, coaching adults and kids in tennis.  Although I was primarily focused on advancing my own career as a tennis player through my early 20s (played three years of college tennis, one of them for a national-championship program), I never strayed too far from coaching, often coaching tennis clinics during my summers off from school.  After my competitive tennis playing days were done, it was a natural fit for me to transition to coaching, at first just tennis, but eventually into general strength and conditioning.

I discovered CrossFit in 2003, and decided to experiment on myself.  I was amazed at the impact it had on my fitness, and started sharing it with others whenever I could.  I got my Level 1 certification in 2004, immediately starting coaching others, and in 2005 co-founded CrossFit Oakland, one of the first 30 CrossFit gyms.  This all happened long before CrossFit had the visibility it does today, and way before the CrossFit Games appeared on TV.

In addition to the numerous CrossFit certifications I’ve attained (I was even awarded the now-defunct Level 3 Coach designation), I’ve also held USAW Sports Performance Coach and Charles Poliquin Biosignature Level 1 certifications.

CrossFit Oakland is such a special place to train and achieve things you probably didn’t even think possible.  I’m humbled to have been a part of it from day one, and can’t wait to see what tomorrow brings.

Lance Velasquez, RKC1/SFG1, Crossfit Level 1, FMS

ldv power cleanLance Velasquez spent years as a high-profile chef in the restaurant industry and at one time was recognized as one of the country’s top ten chefs. In his off-time he used the treadmill as his primary exercise tool. Realizing that he wasn’t seeing the results he wanted in life or in health, Lance changed his fitness style and joined Crossfit Oakland. He began training in kettlebells, olympic and power lifts, as well as doing high-intensity metabolic conditioning workouts. After losing over 50 pounds and improving his fitness level and cardiovascular health, Lance decided to hop off of the proverbial treadmill, leave the restaurant business, and fulfill his dream of becoming a personal trainer. Lance also participated in the 2008 Crossfit Games in Aromas, prepared healthy meals for the 2009 Crossfit Games and continues to compete in throwdowns and lifting comps. Since realizing his passion for fitness he has earned his Russian Kettlebell Certification, Level 1 Crossfit certification, as well as Robb Wolf’s Nutrition Certification. He’s currently training for his level 2 Strongfirst certification and trains with Max Aita to improve his knowledge of powerlifting and olympic lifts. He teaches Crossfit classes, kettlebells sessions, bootcamps and personals and, because Lance believes that 80% of your health and fitness can be attributed to what you put into your body, he also leads paleo cooking seminars for his clients.

As a trainer at CFO, Lance has incorporated into his coaching the importance of proper body mechanics. He is also conscious of the importance of appropriate rehabilitation and rest. Lance’s passion for the wellness of others has helped many individuals with varied goals to become more fit and healthy. Using his knowledge of the musculoskeletal system, his understanding of the importance of functional fitness, and his 35 years as a creator of delicious and healthy foods, Lance has all of the tools in his toolkit; do you want to build muscle? Lean out? Get stronger? Increase endurance? Lance can help you to do all of this, and he’ll make sure that your time working out with him is the most fun you’ll have all day, so that you can’t wait to do it again tomorrow.

Robyn Alazraqui


Robyn is humbled and grateful every day to be a part of a community that supports, encourages, teaches and affects change.

Several years ago she left the corporate world behind to manage and coach classes at CrossFit Oakland. Finding the CrossFit program and community was literally life-changing and now Robyn has the privilege to continue this life-changing work. She appreciates that hard work, commitment and discipline, as well as a supportive community, is rewarded in the gym – and in life.

It is Robyn’s goal to continue to spread the word about fitness, nutrition and lifestyle to as much of the population as humanly possible, while pursuing excellence in all aspects of her work – from running a small business to pursuing more advanced education, while empowering herself and her clients to pursue any dream, even the ones that seem impossible.

Robyn’s greatest joy is watching her clients, friends and family succeed where they never imagined they could.

Michelle Maehler

MaehlerI’ve always been fascinated with movement and how the body works, on both a physiological and bio-mechanical level. My initial coaching experience started in my teens during my competitive years as a power tumbler, I eventually outgrew power tumbling and during college competed in GS and Boardercross as a snowboarder. In love with snowboarding and fresh out of college, I moved to Colorado to teach snowboard lessons to the masses. I learned a lot about movement efficiency (because snowboarders are lazy) throughout that time, and it inspired me to go back to school. I received my Masters in Exercise Science with an emphasis in biomechanics from UC Davis in 2010, and shortly after moved to the bay area and found Crossfit Oakland. I’ve been Crossfitting ever since and have also done a number of competitions, including the 2012 and 2013 NorCal Crossfit Team Regionals.

I received my Crossfit Level 1 certification in January 2013. The gains I’ve seen from Crossfit go well beyond a bigger back squat (but, that too!) and I’m happy that our gym is a place that so many of us look forward to going to everyday. I’m looking forward to coaching more and continuing to geek out on proper mechanics and movement efficiency.



Brendan Walcoff

I’ve been around sports my whole life. From baseball to football, tennis to rugby, and now weightliftiBWalcoffng, I have always had a passion for competing and pushing my limits both physically and mentally. When not slamming bars and crushing PRs I love to help others achieve their goals. Whether it be helping my mom run a quarter mile or a collegiate swimmer better his times, I get more satisfaction helping others achieve than I do in my own achievements. I am absolutely obsessed with optimizing human performance and am always eager to learn and be proven wrong.




Colin Cunningham


CCunninghamColin started his fitness journey at four years old when he was introduced to Okinawan Karate.  He received his probationary black belt at sixteen and then started to study other martial arts under J. R. Roy, Remy Presas and T.T. Liang.  After finally receiving his official black belt in Karate and Arnis, Colin left the country for University in Europe.  There he studied English and Modern History at St. Andrews of Scotland where he continued to teach Karate and Tai Chi.

Colin later returned to America and found work in the restaurant industry.  There he moved from intern to line cook and then to pastry chef.  Eventually he opened his own cafe which, unfortunately, closed within a year.  Heartbroken, he returned to training people in fitness and self defense.

Colin started training in Mixed Martial Arts at Wai Kru MMA in Boston, MA.  Shortly thereafter, he brought his fitness experience to the gym with a strength and conditioning program. Additionally, he was the strength coach for UFC fighter John “Doomsday” Howard.  A few years later, Colin found Crossfit as a varied and new form of fitness for the competitive fighters at Wai Kru and realized that it was the sport for him.
