Diane was great to work with in finding our property. She knew what we were looking for and made sure to keep us updated on all properties available. Always willing and happy to answer all our questions. Very supportive during the property inspection and at closing. We will use Diane again and recommend her to family and friends.

Diane did a great job selling my condo. It was easy to get in touch with her by text and phone and she had lots of information available for me. She kept me informed continually about showings and potential buyers. Even after closing on the sale of my condo, she takes any questions I have about the sale. Members of my family have worked with Diane in the past and some are working with her now.

Diane gave great tips on how to stage our homr and even provided items to spice things up a bit. The pictures and marketing were on point and as a result, our house was only on the market for a short period of time. We sold for asking price and would highly recommend. Diane is professional, knowledgeable and is a great communicator.

Sr. Underwriter
Diane was extremely professional during our entire selling process. From the moment she entered our home for the first time, to the last time, Diane listened to our wants and needs. She gave advice from her experience, yet allowed us to make our own decisions. Diane worked hard to get our home noticed from the very beginning. We were very fortunate to sell our home within 48 hours and I believe that she was instrumental in this sale due to all of her advertising of our home. Diane maintained her professionalism, yet became our friend through the process. I would not hesitate to recommend Diane as your real estate agent.

Owner John Scott Musician
After dealing with several agents who just brushed us the wrong way or failed to do the necessary work, we were introduced to Diane. Immediately, we had a personal connection with her friendly, yet extremely knowledgeable, personality. I'm not sure which was more enjoyable: The actual house showings or The conversations with Diane during house showings. We met more than an agent. We sincerely met a lifelong friend. Diane is professional, yet personable, friendly and extremely knowledgeable about real estate.

Have used Diane for four property transactions. All were expertly handled and the advice and support she provided was invaluable. We looked for our last purchase for quite some time and we had very specific criteria. Diane patiently worked with us until we found the perfect place. I highly recommend her as an agent.
