Meet Our Staff

Mike and Cheri Tillman

Mike and Cheri are the owner/operators of Pro Cyclery.  Mike was an avid road biker - he got his first road bike primarily to improve his health and, after huffing and puffing through his first 10 mile ride was hooked.  He's not riding as much now, but loves the sport and supporting all our customers.

Cheri claims to be the best SAG around.  Her claim to fame is hauling six kids and a pop-up camper from town to town as Mike completed the Bike Ride Across Nebraska.  She will tell you she's not a great rider, but loves the smile that riding puts on her face.

If there were a definition for Mom and Pop Shop in the dictionary, Mike and Cheri's photo would be there as they are the Mom and Pop of seven kids and extremely proud grandparents of two.

Lelani Gonzalez

Lelani is Pro Cyclery's shop manager.  If you have a question about a bike, an accessory, a price, a sock, a helmet, an order date, a shipping price, a bike route, or where to find the best sandwich for lunch, Lelani knows the answer.  She can tell you anything you need to know about your bike or a bike you are interested in purchasing. Lelani is an avid cyclist, riding both road and mountain, who is always seeking to develop the women’s cycling community.

Penny is Pro Cyclery's official greeter, but her title is Chief Dog Operations Officer. Penny is a Golden Doodle and, although she barks pretty loudly, is afraid of almost everything and is very friendly. Penny gets phone calls at the shop (yes, customers want to be sure she's here before they come in) and gets Christmas and birthday presents from our customers.  If we had a dollar for every customer who wanted to take Penny home, we wouldn't have to sell bikes anymore.  Come in and say hi to Penny.
