About

Success starts with a show.

Sold by Sierens Event Services for schools, non-profits, organizations and auctions.

Roger fell in love with the rhythmic auctioneer’s chant when he was an eight-year-old farm boy in Illinois making the farm auction rounds with this father. After building a successful business career, he followed his heart, attended the World Wide College of Auctioneering, and manifested his boyhood dream.

When Roger stokes the auction fires at the events he conducts, the crowd is swept up in his enthusiasm as he rolls between entertaining performance and serious fundraising, with professional ease.

Professional auctioneers are skilled in keeping the focus on raising money while delivering revenue-raising showmanship. Roger deftly employs his skills, passion, and energy to incite spirited bidding and create record-setting, charity auction proceeds.

If you are looking for an auctioneer for your event, look no further than auctioneer extraordinaire Roger Sierens. 

We have been putting on successful fundraisers for many years, the last 12 years for TAPS (Tragedy Assistance Program for Survivors) which helps the families of our fallen military heroes. 

However when Roger came on board 8 years ago, because of his expertise, our live auction sales soared to record numbers and have continued to grow and set records every year, raising nearly $330,000 this year! ($130,000 last year)  He has been phenomenal.

Roger's class, charm and professionalism along with his superb stage presence set him apart from other auctioneers which, along with his ability to connect so well with the audience, is why he is able to raise the big dollars!

He is wonderful to work with and has given us guidance and many great suggestions to make our auctions even more successful.

I cannot recommend Roger highly enough.

Your contribution was enormous and very clear to see, as the auction has generated more than expected both this and last years, the two with which you were involved. Having you at the auction gave it a tone of professionalism and focus. I also appreciated how much you were able to personalize your approach, remembering all the details of our fundraising effort, names and stories.

The Foothills Academy Annual Gala and Auction was an overwhelming success, attracting almost $100,000 in support of our mission…Countless parents and guests complimented your energy and playfulness in generating bids and moving along the live auction portion of the evening.
