Owner & Head Coach

Jenny’s lifelong involvement in athletics naturally led to coaching. In college she developed her skills teaching Tang Soo Do and Doce Pares studio. Jenny expanded her athletic passion, incorporating pilates and static trapeze to performance level.

When she stumbled upon CrossFit, she was immediately hooked. After working to earn her level 2 CrossFit (now referred to as level 4) coaching certification, she opened United Barbell. Jenny followed her passion to become a national level Olympic lifter, currently competing for the California Strength Olympic Weightlifting team.

Jon Schoenherr

Instagram: @jschoenherr

CrossFit Coach

While he doesn't have Superman's strength or speed (yet!), Jon does love comic book characters and mutants.  At UB he coaches other super heroes - YOU.

Jon was a hardcore soccer player throughout his young life.  But into his 30s, retired from soccer and bored from years of globo gyms and P90X, Jon found UB and found the only other sport he wanted to play as much as soccer - CrossFit.   He enjoys teaching CrossFit too, and in helping you discover your inner mutant.  Jon values safe, quality form and technique.  He'll cheer you on to break new boundaries, but only when your body's ready for it.

When not coaching, Jon can be found in UB pushing his own limits.  He loves competing, and now after turning 40 he can play against people his own age in the Masters division.

CrossFit & Powerlifting Coach

Steve walked into the doors of United Barbell just wanting to learn. With no formal athletic background, he was a quick learner and was passionate at getting better. Steve obtained his Level 1 a year later and starting helping others who started just like him.

He loves to teach and takes great joy in seeing others succeed. He will forever have an eternal fire for "just wanting to know" and has already studied many different powerlifting and body weight strength modalities. He continues to increase his knowledge through other Crossfit and other certifications.

Nikki Staley

CrossFit Coach, Nutrition Consultant

A former Bikram Yoga practitioner, distance runner and triathlete, Nikki was known for jumping around from active hobby to active hobby.  But for some reason CrossFit has kept her ever-active mind entertained. Maybe it's that "constantly varied" thing. Or maybe it's all the awesome people she gets to work with every day. Nikki's true passion is helping people reach their goals, especially when it comes to their health and wellness. In 2012, she left her corporate work in human resources to pursue a career in fitness and nutrition. She runs her own business as a Health & Nutrition Coach, and also does volunteer work with groups like Cooking Matters. Nikki is also on the Board of Directors for Westside Athletes Associations, a not-for-profit organization that implements functional fitness programs in SF Bay Area middle and high schools.

Shannon de Peralta

CrossFit Coach

Coach Shannon is a gymnast, turned dancer, turned CrossFitter.  She made the switch to CrossFit in 2012, after a nod from one of her former teammates, and has hit the ground running since then. Her favorite movements to coach are the highly technical, which is mostly attributed to her previous experience coaching women's artistic gymnastics during college. Outside of coaching, she also competes in CrossFit competitions, has goals of competing at California Regionals, and enjoys yoga on days she's not training. Shannon studied kinesiology and biochemistry at the University of San Francisco, and her purpose through coaching is for her athletes to see the beauty and strength of which their bodies are capable.

Max Cantor

CrossFit & Powerlifting Coach

When Max first moved to San Francisco in 2012, he wandered in to United Barbell but didn't fully appreciate the community and benefits of CrossFit's group fitness classes and did not join at the time.  Instead, he continued strength training on his own with some distance running.  After completing the SF Marathon that year he got disillusioned with running and gave up conditioning completely.  

In 2014 he gave Crossfit and UB a second look and became hooked for life. While Max's strength and conditioning gains quickly eclipsed anything he imagined was possible, the changes in his personality, outlook, and confidence and the changes he has witnessed in so many other members of the UB family were even more striking.  Waiting two years to join UB is one of his few regrets. 

Max is passionate about teaching along with health an wellness so coaching was a natural option.  Along with every UB coach, he is a strong believer in using proper technique to help every athlete in his class safely push their limits.

When Max is not coaching or working out, he runs Research and Development for a business software firm in San Francisco.  He is also a private pilot and his two favorite places in the world are anywhere under a barbell or anywhere a few thousand feet above one.
