Testimonials

Read what my clients have to say about working with me.

"We had an incredible experience working with Diane to buy our new home and sell our previous one. From day one, she was confident, thoughtful, and incredibly knowledgeable, with a clear plan that made the entire process feel smooth and stress free. Her deep relationships and reputation in the San Diego real estate market were absolutely critical in helping us secure our home. Without her connections and expertise, we truly would not have been able to get it. She also guided us through selling our old place with ease and confidence. We are so grateful for everything she did for our family and could not have done this without her. If you are deciding who to work with, Diane is hands down the expert you want."

"Diane is very smart, is skilled at collaborating with others to get things done, and is very hard working. No one will outwork Diane. In addition, she is kind, trustworthy and honestly… fun to work with and be around. I highly recommend Diane Mills and her company for all your real estate needs. They have been a great help to my husband and I."
