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. She leads rides, gives informational clinics, and acts as a go-to resource for cycling related information. In Lelani's off time, she rides, takes care of her family and shepherds her two teenage sons. 

Jayme Ray

Jayme is our service shop manager.  He says he likes bikes and that's all you need to know.  He started working in bike shops at age 12 and began racing mountain bikes competitively at age 16.  He has worked as a bike mechanic for several years and has experience in retail management.  He represents Pro Cyclery at local cycling events - look for him under the Pro Cyclery tent at many charity and competitive rides. Jayme rides road, mountain and gravel and will be happy to get your bike in great working condition or help you find the new bike of your dreams.

Ron Loomis

A.K.A.  Dr. Ron, because there's no bike he can't fix.  Ron has more than 30 years experience building and repairing bicycles and is one of only four master wheel builders in the Valley.  Ron rides mountain and road bicycles and motorcycles - if it's on two wheels, Ron will ride it.  In fact, Ron has never in his life owned an automobile.

Adam Helzer

David Dasta

David works as a mechanic for Pro Cyclery when he has time off from his full-time job.  David races both mountain and BMX bikes and has raced for KHS since 2000.  He currently races in the 40 and Over Expert class.  He also helps kids learning to ride BMX at the local track. He has been associated with Pro Cyclery since 1999 and, though he's not an official employee, he is a big part of the Pro Cyclery family.

Ryan Johnsen

Ryan is an avid mountain cyclist, experienced tour leader and a certified mountain bike instructor.  He is new to Las Vegas and adjusting to our weather versus Michigan weather - we think he'll be thrilled when he can ride here year-round.  If you have any questions about your bike, your shoes, helmet, best trails or anything else bicycle related, Ryan will be happy to answer.

Clay Weeks

Riding competitively almost since he could walk, Clay is a mountain biker who loves the sport and will help you find the right bike for your cycling goals.  Between working and riding, Clay is a photographer who loves hiking out into the desert to take amazing photos of the night sky.

Cesar Gonzalez

Cesar will help you with just about anything - from answering any questions you may have about the bikes we carry to actually carrying your bike to your car.  He is an avid cyclist, riding both road and mountain and is also learning as much as he can about maintaining and/or repairing bicycles.

Marc Reisman

Marc is a Las Vegas native who has been a cyclist his whole life.  He has raced both road, mountain and gravel so can give you lots of help choosing the right bike no matter what aspect of the sport excites you.  He has been a part of the Vegas cycling community for more than 30 years and is a League of American Cyclists certified instructor.  


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.
