2018-2019 SHARE Officers

Steve Larson – President
SHARE President for the past four years. Steve has also previously served on the Board as the SHARE secretary for 3 years and has been a SHARE member for over 10 years.

Steve and his wife Carolyn reside in Huntington Beach.

Paul Miller – Vice President
SHARE President for three years and Vice President for his fourth year, Paul has been a Park Representative for 9 years (Peters Canyon and Santiago Oaks Regional Park) and a SHARE member for about 15 years. Paul has been instrumental in increasing the visibility of SHARE in the MTB community and in the county parks. Paul’s favorite SHARE memory: “End-of-Season parties in the El Moro Parking lot. Especially the games. Ghost Ride. Fill the bucket with water bottle race. Two people, squeezing water bottles between their knees (no hands), whoever filled the bucket first won.” Paul can be seen navigating his single speed rigid mountain bike on father/daughter rides with Liberty.

Daniel Eitman – Secretary
New SHARE Secretary, Dan has been involved in SHARE for many years.

Brad and his wife Chris reside in Newport Beach.

2018-2019 SHARE Directors

Communications Director

Jon Kearley – Park Rep Director
My name is Jon Kearley and riding my bike is a huge part of my life. All my friends ride bikes and I’m meeting new ones on the trail everyday. I’m also addicted to trail work and trying to make our trails more Sustainable, Safer and Fun. In an effort to be a better rider I am focused on picking safer lines, not fast ones. I never want to stop challenging myself and others. I look forward to see you out on the trails.

Martha Welch – Volunteer Coordinator
Martha has been a SHARE member since 2014 and was appointed as the SHARE Volunteer Coordinator in 2018. This role is responsible for managing the volunteer program for SHARE which was established to ensure that volunteers are available to assist the Orange County Parks, California State Parks, mountain bike related organizations, and SHARE at their various sponsored events. After spending many years riding her mountain bike in Whiting Ranch Wilderness Park, Martha welcomed the opportunity to become the SHARE Park Representative for Whiting Ranch – she enjoys working with the OC Parks staff and rangers to coordinate and attend trail maintenance days and to assist the staff with mountain bike related events held in the park. When she is not mountain biking, Martha enjoys road trips with her family and friends and any activity that is in the outdoors, especially hiking, snow skiing, and camping.

Mike Soursby – Sponsorship Coordinator
Mike (know around as “MTB Mikey”) is a founder and club leader of the thinkMTB Club.  He started that club with 3 other riders in 2010. He is retired from Kawasaki Motors (after 36 years) as their Data Center Manager.
Mike can be found riding in the dirt almost every day.  Slowly, methodically, and taking many stops to “smell the roses” or to take selfies of him and his many friends that join the rides. He also started the bike bell program for LCF and works with Martha to keep it active and spread among the many OC parks and riding areas.
Mike loves what SHARE is about, and was given this position by Steve Larson in 2018 to keep him occupied, and hopefully keep the sponsors aware of SHARE and the benefits to members intact.
