Dorothy “Dorrie” Bruggemann – Outreach, Equity + Diversity

Dorrie has lived in San Diego for a year and a half, and does work in
voter outreach and community organizing. She has many memories of
bicycling while growing up in Iowa, and enjoyed bicycling as her main
form of transportation while living abroad in Spain for several years.
Returning to the States and moving to San Diego allowed her to
realize the extent to which cars are prioritized in our transportation
systems. After living here over a year, she still finds herself sometimes
afraid to explore new areas on her bike due to safety concerns. She
sought out SDCBC in the hopes of helping create a San Diego where
people from all walks of life can get around safely and comfortably
using their bicycles, and where bicycling as a means of transport is
viable across the entire city. As a board member, Dorrie will represent
young, female, and casual bicyclists, and those who want all people
and communities to be able to share the joy of bicycling!

Club and Organization Members

Paul Gorman – CycloVets

Serge Issakov – San Diego Bicycle Club

Serge Issakov has been a member of the Coalition board representing the San Diego Bicycle Club since 2004. He chaired the Council of Clubs previously and is currently vice chair. Member of Advocacy committee. Serge is a League Certified Instructor. He also sits on San Diego’s Mobility Board representing District 1, and serves as Secretary on the board of the California Association of Bicycling Organizations. Serge is skeptical about the effectiveness of most bike infrastructure in terms of significantly increasing ridership and improving actual rider safety. He believes more emphasis on education and marketing good traffic cycling skills and practices would be far more effective at making cycling safer, more enjoyable and more attractive for anyone 8-80. He would like to see more emphasis on getting the 2% of the population that does 90% of the riding to use bikes more for commuting and other utilitarian trips.

Howard La Grange – Bike/Walk Alliance

Howard has been an active cyclist for over 60 years and a member of the Coalition since 2005.  He continues to promote active transportation currently working as the Active Transportation and Micromobility Coordinator for the City of Oceanside.  A League Cycling Instructor since 2000, he teaches Smart Cycling classes and holds bike education rodeos for elementary schools.  He has worked with the Coalition to form local advocacy organizations (BikeWalks) to promote active transportation in their communities.  The goal is to have the regional BikeWalks work with their local municipalities in promoting biking and planning bike facilities.

Mark Semancsin – Bike Buddies

I am an ex runner and running coach that can no longer run. Now, after retiring from a management career, I enjoy cycling, working out at the gym, Pilates, Yoga, all to stay in shape.  Due to gyms being closed and less activities from Covid 19, in the first 10 months of 2020, I rode over 11,000 miles with 650,000 ft of climbing on my bike.  My greatest recent achievement was a solo, unsupported ride of 208 miles in one day in June, averaging over 15mph.  I’m fulfilled from leading rides for the Bike Buddies Cycle Club.
