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.

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.

Leka Fineman

Leka has been a life-long student of  movement, health, and fitness.  She grew up riding horses, surfing and practicing yoga. She was introduced to CrossFit in 2008 by her brother, Moses, and just to get him to shut up, went to a class. She was instantly hooked, and immediately fell in love with the constantly varied intensity and the community.

In 2017 Leka placed 7th in the world (50-54) at the CrossFit Games in Madison, competed on Team CrossFit Oakland at the Norcal Regional in 2014, and is a 3 times NorCal Masters Champion (2015, 2017, 2018).
Leka is passionate about sharing her experience and knowledge with others to help them be the best they can be, and find the joy that comes from achieving things you never thought possible in the gym and in life.

Michelle Maehler

Michelle has always been fascinated with movement and how the body works, on both a physiological and biomechanical level. Her initial coaching experience started in her teens during her competitive years as a power tumbler. She eventually outgrew power tumbling and during college competed in GS and Boardercross as a snowboarder. In love with snowboarding and fresh out of college, she moved to Colorado to teach snowboard lessons to the masses. She learned a lot about movement efficiency (because snowboarders are lazy) throughout that time, and it was those days on the mountain that inspired her to go back to school. She received her Masters in Exercise Science with an emphasis in biomechanics from UC Davis in 2010, and shortly after moved to the Bay Area and found a home at Crossfit Oakland and later, Endgame Athletics. She has been Crossfitting ever since; she has completed every Open since its inception in 2011 and has competed at the Regionals level every year since 2012.

She received her Crossfit Level 1 certification in January 2013. The gains from Crossfit go well beyond a bigger back squat (but, that too!) and she’s happy that our gym is a place that so many of us look forward to going to everyday. She loves working with people and seeing and sharing in their successes.  She looks 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.
