Personal Trainers in San Francisco



Jamie Stanic - Fitness Manager

Jamie started his career in fitness as a personal trainer to support his education in nursing. He reached state level fitness competitions and coached bodybuilders to the Australasian IFBB titles. After his employment in the Australian Army, Jamie became a Special Forces Army Commando. As a combat fitness leader, he applied CrossFit as a tool to combat fitness and rehabilitation amongst the members of his commando unit. Years of rock climbing, cycling, playing Australian rules football, personal training and combat fitness helped Jamie in getting certified as a CrossFit coach in 2008.

Jamie has continued to educate himself in CrossFit and other fitness fields and has coached in many boxes across Australia. He has been involved in supporting the Australasian Regionals and has competed in numerous open day competitions.

Jamie now dedicates his time to his two boys while continuing to coach athletes of all levels.

Andrés De la Rosa
Andrés De la Rosa started his coaching career in 1995 coaching gymnastics for the City of Davis Parks and Rec while being a member of the UC Davis Men’s gymnastics team. In 2005 Andrés was invited by Roger Harrell, the original gymnastics Subject Matter Expert for CrossFit Inc., to help teach CrossFit trainers how to coach basic gymnastics skills to athletes, clients and other coaches. In addition to coaching, Andrés has competed in the very first two CrossFit Games in Aromas in 2007 and 2008 and more recently, the 2011 CrossFit Games Open.

In 2006 Andrés co-founded CrossFit Marin, the first Marin County CrossFit Affiliate, with Roger Harrell. This gym, now known as “The Cave”, has the most comprehensive schedule of adult and kids gymnastics, parkour and CrossFit classes in Southern Marin. With his team of parkour coaches, Andrés have designed and hosted parkour and “Ninja Warrior” style obstacle course competitions and national parkour jams that have made the gym widely known in the parkour community.

Andrés is realistic and honest about how CrossFit relates to climbing and is happy to help climbers attain their goals at whatever level they find themselves.

Sarah Powers

Sarah began CrossFit in 2010 when she stumbled upon CrossFit East Bay at her local rock climbing gym. She has been crossfitting ever since as a way to compliment her running, climbing and competitive cycling. Sarah became a certified CrossFit trainer because she wants to help people discover the ways CrossFit can compliment many aspects of their lives.

Whether she is working with a competitive athlete or someone simply looking to stay fit and healthy, she uses patience, encouragement, and goal-setting to adapt to their needs. Her goal is to help you make mind-body connections as you gain strength, power, mobility, endurance, balance, and confidence.

In addition to her work at the gym, she is a full-time lecturer in the University Writing Program at UC Davis.
