The Board

We are a hodgepodge group of mechanics, number crunchers, tech gurus, and marketers that have come together to make the Midlands a better place for cyclists.

Scott Nuelken

Executive Director

Executive director of Cola Town Bike Collective (CTBC) since March 2021, Scott Nuelken served as president of the board of directors of CTBC from April 2015 until his transition into the nonprofit’s first paid leadership role. As leader of one of South Carolina’s only nonprofit bicycle shops, Nuelken works with the board, volunteers, donors and grantmakers to further CTBC’s mission to provide reliable transportation to an array of communities in the Midlands region.

An Eagle Scout with a long history of community service, Nuelken is an avid bicycle user and staunch advocate for cyclists’ rights and for equity for underserved communities. In 2012, Nuelken co-founded CTBC and collaboratively grew it from a grassroots initiative housed in a residential garage to a full-fledged charitable organization that has secured grant support from funders like BlueCross BlueShield of South Carolina and Central Carolina Community Foundation. With his colleagues at CTBC, he has developed products like the Sprocket app, which features curated Midlands cycling maps to help local cyclists connect with safer routes. In addition to managing CTBC’s retail bike shop located at the Elmwood Ave. overpass in downtown Columbia, South Carolina, he works with local human services charities like Transitions, Lutheran Services Carolinas, Providence Home and Catholic Charities of the Midlands to provide bikes at low cost or as a donation to those in need. He has volunteered with various organizations to support those impacted by natural disasters, and he has served on Columbia’s Bike Pedestrian Advisory Committee (BPAC).

Regan serves as Executive Director of The Echo Project and is a native of Laurens County. He is a graduate of the University of South Carolina. Regan co-founded The Echo Project along with Rev. Kennedy and members of NBMBC. He is driven by a passion for civic service, the fight against injustice, and a hope for a better South Carolina.

He has completed his MBA from the Darla Moore School of Business and was named in the State Newspaper’s Top 20 under 40 in 2019.

As a founding board member of the CTBC in 2015, David has worked towards expanding access to transportation and advocating for safer roads for pedestrians, cyclists, and motorists. David has served on Columbia’s Bike Pedestrian Advisory Committee (BPAC), been involved in grassroots advocacy groups, and has written numerous grants to create virtual and physical cycling infrastructure around the Midlands.

Jacob Oblander


Jacob is a lifelong outdoorsman and advocate for human powered movement. He moved to Columbia three years ago and immediately found himself volunteering at the shop. From there he has become the Volunteer Coordinator and a Board Member. Previously he worked with the Lower Savannah River Alliance and Savannah Riverkeeper advocating for a healthy environment and outdoor recreation.

Jacob works as an Environmental Health Manager at the SC Department of Health and Environmental Control, and holds Masters of Science in Environmental GIS. He can be found throughout the Midlands enjoying human powered adventure in his free time.

Jaclyn Kawsky


Jackie is an Ohio native who relocated to Columbia, SC in 2014 for work as a Mental Health Clinical Pharmacy Practitioner with the Veterans Health Administration. She completed her Doctor of Pharmacy from the University of Cincinnati in 2011, followed by two years of psychiatric pharmacy residency training at the other USC in Los Angeles, California. 


Her love for the cycling community started in college when she befriended a local bike team. After that, she was all in supporting her local bike co-op, volunteering for alleycat checkpoints, racing goldsprints, and cheering on her crew at cyclocross races. After a long, post-college biking hiatus, she knew that the Cola Town Bike Collective would be the reentry point to the cycling community. Jackie first volunteered with CTBC in 2019, helping to keep our shop organized and events running smoothly and spearheading grant pursuits for bikepacking adventures. She joined the board in January 2023. Jackie is currently involved with Cola Women Cyclists, a community for women, trans, and femme cyclists, and can be found on other local group rides. When not biking she is creating an amazing backyard garden or foraging mushrooms.
