We were pleased with a very up front approach to dealing with us. You used a business like approach to us when you showed us places to purchase and when you listed our home...We had smooth operations with both closing of the place we bought and the one we sold. It was a pleasure to work with you.

Sue is available, professional, and extremely pleasant. It's very obvious that real estate is her profession, and that she is a professional, not an amateur or "hobbyist." She is well-connected and knowledgeable about all aspects of a real estate transaction and knows her market well. Her colleagues are equally professional and personable, and we appreciated her whole-hearted commitment and dedication.

Just a quick note to let you know how pleased I am with your company. I needed to sell my condo quickly so I listed my condo with you and 12 days later I had an accepted offer! Your whole team worked well together, and I’m impressed with the way the marketing, prospecting and closing was handled. I really like that there was always someone available to answer my questions. I look forward to working with Mammoth Realty Group in the future.
