Bill Mohler

billBill Mohler is anything but common. He is as diverse as his background, a mix of east and west, traditional and futuristic. Bill is a communicator, a facilitator, an educator and a student.

Bill has been working with pain management and posture work since his own diagnosis of degenerative joint disease over twenty years ago. What followed was nearly two disempowering decades of chronic pain; treated the standard western way of medications, the inevitable surgery, and the diminished ability to live the life he wanted. The discovery of yoga began a new cycle…one of self empowerment.

No stranger to fitness, yoga seemed different somehow. Under the guidance of Brian Monnier, the strenuous Bishnu Ghosh lineage of hot yoga became a nourishing physical fitness with unexpected meditative and introspective side effects. Noticing improvement in his own pain levels, Bill completed a 200 hour certification in hot yoga, followed by a 500 hour advanced certification. Bill loves communicating his passion for hot yoga, alongside his own version of Yin Yoga, called Yintuition. These styles combine for Bill in a perfect universal balance of yin and yang.

Yoga is only part of Bill’s extensive familiarity with the human body. A skilled bodyworker trained in shiatsu, deep tissue and other styles, he was drawn to the self-empowering work of Yamuna Zake, creator of Foot Fitness and Bodyrolling. Now certified in these two modalities, Bill loves facilitating the dialogue between our bodies, our breath and our minds – teaching how to be one’s own healer.

Never fully leaving behind his passion for fitness, Bill was trained by NASM and received his fitness training certification years ago and is currently working on becoming a C.H.E.K. Exercise Coach. Being an educator of posture and pain management, these components of fitness training really round out his experience. In this way, the teacher remains a student, allowing Bill to connect so effectively with his students and his clients.

Credentials alone can only say so much. Bill’s passion for life and for his work says it all. The pain pills and days of diminished activities are gone for him, and they can be for you too! Learn self empowerment with Bill!

I am a very active person.  My first full marathon was with Team in Training for the Maui Marathon in 2004 and continued my running with various races including Women’s Nike in 2005, 2007, 2008, 2009, 2010, 2011.  The most recent accolade was Maui Half Marathon 2012.  Only activities with lots of movement peak my interest: hiking, tennis, dance and Bar Method.

I have been in and out of yoga for more than 5 years.  Nothing seemed to capture my attention.  But in 2010, my girlfriend who had 2 hip replacements, bought me my first class and introduced me to California Yoga Company.  It was a match!  Brian’s teachings of inner core strength just resonated with me.  Soon after, I became an instructor there, trained in Brian’s Monnier Method; a unique method of Hatha Yoga.  It is the next step in the evolution of the Bishnu Ghosh lineage.  The Method has been put together based on the 84 classic asanas taught by Tony Sanchez.

My strength lies with being in retail/communication for over 30 years.  I have a strong sense of the female body because I work intimately with their needs throughout the years of owning my own business; My Boudoir Lingerie

The goal of a perfect Yogini should be to teach others the joy of YOGA because they themselves love what they do!

I fell in love with Hot Yoga in 1997, having moved to San Francisco fresh from Cleveland, by way of Syracuse University, New York, with my BFA in hand in Metalsmithing and Fashion Design. Coming from a lifetime of dance performance, yoga was the next natural progression as I soon discovered the life-changing benefits of a regular, committed practice, witnessing my body transform and mind focus.
Since my early Bikram days I knew I wanted to teach yoga, but it wasn’t even a remote possibility until I began taking classes from Brian Monnier, whose attentive, intuitive instruction helped me to finally comprehend what true alignment was in my own body. Being a part of the Cal Yoga community feels like coming “home”, and Brian’s dedication to the well-being of its members is the honest, real deal and reason I decided to make teaching yoga a reality.

Admittedly, I am a workaholic, with a soul-fueling career as a professional jewelry artist, active in the arts community, however it can be a cause of many stressors. Yoga keeps me sane, healthy,  and brings it all back into perspective. As a teacher, my desire is to lead others toward finding their internal balance (both literally and figuratively) that yoga has helped me achieve.

I am originally from London, but have lived in the Bay Area for many years.  As a single Mom, I spent many years working for attorneys in order to raise my son and daughter, but about four years ago I realized I wanted to change directions and teach yoga for the rest of my life.  I had sporadically practiced yoga through the 80’s and 90’s and then in 2005 discovered Bikram and loved it until ACL reconstruction curtailed my practice for several months.

An on-line coupon brought me to Brian Monnier’s California Yoga Company in April, 2010 and within a few classes I was hooked!  I knew I had found a style of yoga which made sense to me and nurtured my body, mind and spirit and that this was the yoga I wanted to teach and to practice.   I completed the Monnier method teacher training in April, 2012 and am thrilled to be teaching at the new Polk Street studio and to be learning and growing under Brian’s watchful eye.  I love the community and the teachers at California Yoga Company and look forward to my continued growth and sharing with you all the wonderful benefits to the body and soul of a regular yoga practice.
