RV Sales Representative for Transwest Truck Trailer RV, located in Frederick, CO. Specialist

I have been with Transwest Truck Trailer RV here in Frederick, CO since August 2013. I have been selling RVs since August 2006. One of the best opportunities that came my way was the day I was offered the position to join the Transwest Team. Working for a company like Transwest, that is very diverse when it comes to the Transportation Industry, is in my opinion, the VERY BEST!

I am the type of Salesperson that prides myself on product knowledge, staying organized, and staying in touch with the manufacturer reps. This is key to staying up to speed with knowing the product that I sell.

Being with Transwest as long as I have, I have sold many of my client’s multiple coaches; and I look forward to selling you your next coach. If I had it my way; I would be a professional golfer, but that time has passed me up. I love to play golf; however, I have found success in selling fun, which is another term for selling RVs.

Come visit me at Transwest Truck Trailer RV in Frederick, CO; and you will see; you and I are at the right place for a great experience; with a state-of-the-art facility; AWESOME inventory, excellent Service Department, and a Finance Department that will bend over backwards for your needs!! Hope to see you soon here at TRANSWEST!!

Happy Camping!!
