The JAM Circles Team

Board of Directors

Shannon Leach, Board Member and Executive Director

Before starting Gemini Landscaping,  Shannon worked ten years as a landscaper in Mendocino County and mentored with renowned Landscape Designer, Gary Ratway. In 2005, Shannon began his own Landscape business in Sonoma County and has had a successful career servicing the greater Bay Area for over 10 years.

In parallel to his professional career, Shannon began working at The Sierra School of Sonoma County in 2009 where he developed and led a successful mentor program for boys and girls ages 10 – 18 years old.

In his eight years working with youth he taught the students landscaping as well as provided emotional support and guidance as a mentor. He also developed friendships with staff and students with whom he still remains friends.

His passion for personal growth and mentorship led him to the Mankind Project, a nonprofit training and education organization with three decades of proven success hosting life-changing experiential personal development programs for men. As part of his work with MKP, he was introduced to Boys to Men, their youth mentoring program initiative and has completed over 80 hours of mentor training through this group.

As a father himself, Shannon has a passion to support kids. It’s this drive that spurred him to launch JAM Circles in 2016 so that he would bring his commitment to mentorship to a wider audience.

In our times of increasing estrangement between teens and adults, David is thrilled to carry JAM Circle’s mission to ally teens with adults, fostering relationships that enrich them both.

In our society of marked career instability and unrelenting change, he is passionate about imparting “soft skills” to teens.

Skills of emotional intelligence, adaptability, and unwavering self-worth which will serve teens reliably and well into adulthood no matter what the job market presents.

Having participated in three “initiations” of his own —M.I.T.T’s Basic, Advanced, and LP, The Men’s Weekend, and the Vedic meditation course — he knows the timeless potency that a rite of passage offers. It’s a potency to instill a sense of belonging, optimism, and purpose.

Ruben Rosas, Board Member

Born June 11, 1980, Ruben grew up in small community of Cloverdale in Sonoma County. His journey with mentoring started as an adolescent when he became a peer mediator in the 8th grade and assisted in resolving playground conflicts.

After graduating from Cloverdale High School 1999, he discovered a passion for travel, visiting Australia for 3 months. He spent the majority of his winters in the southern hemisphere: Mexico, Bali, New Zealand, Guatemala, Peru, Haiti, Australia and South Africa.

Through travel and life experiences, Ruben learned many skills on how to converse with humans that may not necessarily speak the same language, live the same lifestyle, carry the same customs. Adapting to situations was a highly valuable skill.

He was eventually drawn to an organization called the Mankind Project in July of 2017. This journey into deeper self-awareness, integrity and accountability has also led him to mentoring and travel. He has participated in 2 New Warrior Training Adventure weekends in Australia and 3 here in northern California.

Ruben recently started a men’s group in Ukiah, holds a place in Sonoma County Heretics (an MKP affiliated men’s group), and participates in several others via Zoom meetings. He is a proud member of MKP Men of Color, a NorCal Latino group, and has accepted the role as incoming NorCal inclusion chair, where he is helping develop a group recently created to deal with racism. He has officially been a JAM Circles mentor for 2 years now.

Ruben worked in the wine industry for 7 years before moving into construction, landscaping and odd jobs for the past 12 plus years. He is currently starting his own landscaping business, RR Creations.

According to Ruben, “My passion and love of life brings me to enjoy the opportunity to share my experiences. It is a tough world if we choose to make it that way, but it is also a kind gentle loving world. I want to assist in growing healthy loving community.”
