Hello Lanny !

I wanted to finally write this letter that you and your company deserve to have. Initially when I was in the market for a wood burning fireplace, I was brought over to one of your locations in Calgary. Initially I was planning to buy a large old style, black fireplace. I ended up getting a Wittis stand up, soapstone modern fireplace. What an amazing feature to have in my large acreage style mansion in Balzac west. The thing that sets you guys aside from all other competititon is not your diverse selection, or the warm demo showrooms. It is most definitely the service. It is so obvious that Hearth & Home will not be satisfied until the customer is. Thank you for all the time spent in person, on the phone, and your personal trips all the way out to my house to get the job done. WOW.

I will always remember the experience. More companies need to act the way your guys do.

Thank you for taking the time.

Sincerely,

J. Lowe
