Nine months ago I was looking for a career change and was told there was an opening for an Hearth Specialist at Trappers Fireplace Gallery. After some consideration I applied for the job and here I am today. I've always been a people person so this is a good fit. Although I'm still learning my position there's always support from someone in the Dahlquist team to help me with any questions I may have. It's great to work for a company that truly cares about their employees and customers.

I am completing all my factory training for Heat N Glo, Quadra Fire and Vermont Castings.
