Excellent

Lisa was both extremely professional and completely perfect for “me”. And I’m sure she is what each individual needs her to be in this big moment in our lives. House selling at its finest.

Remarkable Service

Lisa did an amazing job staging our home. Our home sold in a matter of days! Lisa is caring and informative. She makes the transaction seamless. Her office is kind and caring as well. We recommend Lisa a hundred times over! (We’ve used her services twice…so far!)

Sold My House!

This was my first time selling a house. What an experience, ultimately, a great experience. Lisa was totally awesome and basically "held my hand" through the entire process. I'm so thankful for that! Initially, we encountered an adverse buyer, an investor (run when you hear this word), that really created some problems for everybody. Lisa took charge and made things happen as they should. If you want that personal touch when selling your home, I highly recommend you go see Lisa!

"She had prepared a one of a kind, significantly advanced marketing strategy for our home."

Where do I even begin? Lisa was brought to us by fate through a corporate relocation. From the moment she stepped into the door, her personality, enthusiasm and passion for her career in real estate bubbled out of her. She had prepared a one of a kind, and significantly advanced marketing strategy for our home - using social media to hopefully find us a buyer even before we listed. We had tried to sell our home two years prior and we couldn’t give it away. Lisa has a phenomenal photographer. She and him spent nearly all day photographing our home and creating a marketing video. The results blew me away. Our home was listed on a Wednesday night. Thursday morning we had two showings. Thursday night we had an offer for full price. She was patient and understanding with me as I struggled to get through the process. She was nothing but helpful, kind and reassuring. I have no doubt that Lisa and her exceptional talent as a realtor helped sell our home so quickly. I could not have dreamt of a better realtor. I would recommend her to anyone and everyone. If you aren’t using Lisa, you are making a huge mistake!
