"Kathleen and Marina were very helpful, knowledgable, professional and patient during my partner's and my house search and purchase in Fort Lauderdale. At the time we were living in New York and scheduling house showings needed to be fit into our busy schedules which was handled quite well... I am a VERY pleased customer and would use their services again should the occasion arise."

  -Bob Cauley, Client

"Their many years of experience showed! Both were on top of both the buying and selling of our homes. Even after the sale of both properties they were there with good recommendations to getting services done in our new area. They were very easy to work with and extremely responsive either by phone, text or email. Highly recommend them both!!"

Whenever I refer a client to another Realtor I want to make sure they are taken care of and Marina did just that offering great professional service. I will continue to send Marina any clients that are looking in the Florida, Ft. Lauderdale area. Thanks!"
