Our Staff and Board

Executive Director

Judi TentorJudi Tentor lives in Mission Hills, grows a lot of food in her garden, and gets around by bicycle as much as possible. She has been navigating the streets of San Diego by bicycle and transit since 2008 when she sold her Honda Element. Her passion for the environment and sustainability drives her everyday actions. Riding a bicycle, she believes, is more than a fun activity, but also a tool for transportation as well as a solution to environmental, social equity and health issues that matter to her.

Judi is also a Cycling Instructor (LCI #5098) certified by the League of American Bicyclists, the oldest bicycle advocacy org in the US. She teaches beginner classes for adults learning how to ride for the first time and traffic skills classes for intermediate riders through nonprofit organizations. She is an advocate for active transportation and a feminist, hoping to inspire more women to ride bicycles for the benefit of their health, spirit, and the planet.

As a bicyclist, advocate and cycling instructor, she has been leading efforts to get more bicycle infrastructure in San Diego. She currently serves on the board of the Mission Hills Town Council. When not pedaling and sometimes while pedaling, Judi takes photographs of people riding bicycles and bicycle infrastructure around the world. She holds a bachelor’s degree in Environmental Science from SUNY ESF and a Masters of Landscape Architecture from The Ohio State University, and was awarded a Comprehensive Bikeway Design Certificate from Portland State University.

dreAidrea Sparks is passionate about craft beer, organic food, local business, brushing and flossing, music, dance and bike life.  She loves long walks in the city, camping, and travel.  Dre has lived in Hillcrest for 12 years and has been a proud non-automobile owner for almost 10 years.  Her legs get her everywhere she needs to go, whether it be by foot or bicycle.  She has commuted to work via these two modes of transportation since she moved to Uptown and would not have it any other way, at least not until she moves back to the woods where she came from when she is old and grey and sick of the city.  That might never happen.  She loves having so much variation and vibrant amazing opportunities available close by.  Dre completed her undergraduate studies at UCSD and is looking forward to graduate studies in urban planning and sustainable development within the next couple years and is also very excited about working with BikeSD and the community to build a better San Diego for all modes of transportation and styles of living.

While he’s always been an avid cyclist, Tim first began to look at biking as a transportation option when he moved to Mission Hills four years ago and needed to find time for exercise in between a busy work schedule and many needed DIY home renovation projects.  He has been hooked ever since.  In his spare time he enjoys riding bikes on the roads and trails of San Diego, hiking with his wife and dog, sour and wild beer fermentation, surfing and building things.
