What did you like about your experience?

Colleen was phenomenal in every way shape and form throughout both buying our new home and selling our prior one. It was a very stressful experience at times, especially after losing out on many new houses, and Colleen was strong, supportive, friendly and upbeat. She knows a great deal about the area where we were looking to buy and where we were selling, which is why we sought her out in the first place, but the entire experience was even better than we possibly imagined. We believe we gained a great friend in Colleen, more than just being a real estate agent. I'd be happy to recommend Colleen to anyone who will listen!

What did you like about your experience?

What I noticed the most about Colleen was her friendly personality. She is a very busy realtor but always had time for me. I think what I liked most was her honesty. She never tried to sell unless she believed in it first.
