Alexey Davies, Membership Director
Alexey spent too much time in the corporate world polishing his business skills. Now he’s free to do what he loves, creating a culture of cycling at Community Cycles. Alexey is an avid mountain biker / bike commuter who eschews the car in Boulder, but somewhat hypocritically still has a passion for a good road trip for remote multi-day outdoor adventures.

Kerry Kruempelstaedter, Financial Director
Kerry rediscovered bicycling as an adult and loves the sense of freedom and fun it brings. She enjoys commuting around town on the bike paths, pushing herself to climb mountains, sneaking up in the hills for quick overnight bike-camping, and, generally, exploring and experiencing the world by bike. Biking brings Kerry such a fulfilling sense of joy that she’ll never give it up again. Kerry enjoys the opportunity to share this passion with others. Contact her at .
Steve Cepek, Sales Supervisor
I love Bikes! Mountain Biking is what brought me to Colorado 20 some years ago from the sunny shores of Cleveland. I’ve been in Bicycle retail for 2 decades and have passion for all things cycling. I’m lucky enough to have ridden everything from track bikes to downhill bikes and most styles in between. I love helping riders get to their next level, next ride or next adventure. I’m also pretty good at getting rid of aches and pains associated with riding. Contact him at .
Sarah Groenwald, Greeter, Camp Instructor
Sarah began hanging out at Community Cycles as part of the Earn A Bike program in 2013. She now works as a Bike Ambassador and summer camp instructor spreading the good word of cycling throughout the land. She’s always looking for ways to make riding fun and safe, and loves long rides to Fort Collins.
John O’Kelly, Mechanic
My friends and I used to ride bikes everywhere as kids. I got my first real road bike in high school. I raced bikes on the road through college in Tucson, AZ. I did most of my own wrenching during that time. Much later on, I ended up in Colorado. I heard about Community Cycles and started volunteering in October of 2012. After putting in close to 1000 volunteer hours, I was brought on part time. It’s been a blast!
Will P, Mechanic and Learn-A-Bike (LAB)Technician
Will has a soft spot for teaching and helping people learn new things, especially bikes. He loves it when it is crazy busy in the shop and gets to juggle 5-6 projects at once.
Katie Walkden, Sales Associate
Katie likes old bikes. She can be found most days in the shop working at the front desk or on one of her vintage bicycle projects.
Sean Obrien, Fleet Mechanic
Sean joined Community Cycles in 2014 as a bike ambassador. Before moving to Boulder Sean worked as an elementary Art Teacher in the Chicago Public Schools and as a bike messenger in Chicago. He left his car in 2012 and have been commuting by bike ever since and couldn’t be happier. He is currently teaching art in BVSD and working as a bike ambassador, educating and equipping cyclists with knowledge and gear to stay safe and law abiding in Boulder. He is looking forward to instructing summer camp and teaching a new generation of cyclists how to become more independent and knowledgeable on their bikes!
Bruce Piggott, Earn A Bike Coordinator
I became a dedicated cyclist over a decade ago and my first contact with Community cycles was donating a bike in 2008. I became a member and volunteer in 2014 and have never looked back. I thoroughly enjoy all my time spent at CC especially when I’m helping another cyclist repair, maintain or improve their bike.
Melissa Newton, Project Coordinator
Melissa recently completed her Masters in Liberal Sciences and decided to combine her passion for cycling with her passion for helping others. In her free time she competes in triathlons and spends time in the mountains with her furry companion. Melissa loves how friendly and helpful everyone is at CC no matter your skill level! Contact her at .
Bryan Zimmerman, Sales Associate
Bryan’s love of cycling began when he did his first century ride at age 13. He began racing shortly thereafter, at 14. Later in life, he raced at Marian College, participating in road and track racing. Bryan comes to us with many years of experience in the bike world, as he also started working in a bike shop when he was 15. Contact him at .
Jason Gendill, Mechanic
Jason is BACK! Former shop manager (pre-Dax time) is back again with more knowledge about newer/higher end bikes to help manage the donations and sometimes sweet bikes coming through. He likes to “restomod” bikes, taking nice old frames and putting sweet new parts onto. He would love to live car-free again and is working on taking steps to achieve that. He’s been seen around the local Boulder mountain bike trails towing his daughter on his super modified FATtrailer, much of this was done singlespeed. .
Izzy Wilson, Sales Associate
When Izzy tried learning to ride a two-wheeler at five years old she ended up with two black eyes. Luckily, she was able to get back on the bike and has loved riding ever since. After racing as a junior and in college, Izzy completed a trans-am bike tour and moved to Boulder. She’s been having fun exploring the local mountain bike trails and loves working at Community Cycles.
