Where Local Expertise Meets

Personalized Passion

I have a powerhouse of a background! Combining the precision of a Real Estate Agent with 27 years in this business with the high-energy, competitive atmosphere of an Auctioneer (13 years in the business) creates a massive advantage for your clients.

I am not just selling items; I am applying decades of market psychology to "move the needle" on their behalf.
My goal is to take the "daunting" out of the process, giving you the peace of mind that everything is being handled with care and professional precision.

My team has a combined 40 years of experience in their particular fields.
