"Kathleen and Marina helped our family move to Pompano Beach in 2003. Our move was challenging because we have a disabled child, and the move needed to happen very quickly and smoothly in order to provide the level of care our son needs. They not only made it happen flawlessly, but they made it happen in 10 days in spite of multiple challenges related to the seller of the property we chose. Now, 13 years later, Kathleen has done it again by helping us find the perfect condo to meet our son's unique needs. If you are looking for a buyer's agent who truly has the best interest of her clients in mind, look no further. Kathleen and Marina are, quite simply, the best you could ask for. Luke W."

"Professional, Personable & Accessable I wanted to purchase a condo in Pompano for an investment. Driving around I call several realtors from there signs out in of the properties. Kathleen was the only person to call me back and it was on a Sunday. She was able to accommodate my not so easy schedule. Kathleen was such a huge help from the first showing to the closing table. She helped with everything from recommending a funding group to an inspector for home inspection. Kathleen was always right there to answer a question or to make sure the inspection, appraisal were on track. I would highly reccomend Kathleen and her team to anyone who is in the market. It will be the easiest most pleasant experience you will ever have. will be seeing me again. "

"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."
