Diane was awesome! Diane was a real blessing in helping us find the right home. Diane always went above and beyond in answering our questions and finding potential homes that we would like.

DIane has helped me buy/sell 4 houses - - each time, the process has been guided so well by her expertise & energy! She is so skilled, capable and compassionate about helping. She has my 100% trust & that eases my mind considerably. I would highly recommend her!!!

Diane did an outstanding job in the sale of my house. Over and way beyond the required actions. She arranged for cleaning of the house, service of AC/H , step by step explanation of the process. The closing went smoothly via long distance since I had moved to another state by then.
She is friendly, patient, professional and I recommend her very highly.

She was wonderful, it was a easy process thanks to Diane. There was a few miner problems but she was able to take care of it with her negotiation.

Diane was wonderful to work with every step of the way. As first time homebuyers, every aspect of the process was foreign to us, and Diane was always willing to offer advice and tips when we needed them. She knew the area we were searching within extremely well and was always very responsive. She understood the reasons we were asking questions and never made us feel silly for asking things. Her follow-up was excellent and we always felt like she was our advocate. We are just moved into our new home and love it - we would definitely recommend Diane to anyone buying or selling and will certainly work with her again!

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.
