"Kathleen and Marina are true experts and professionals. We told them what we wanted and they delivered immediately. We took the first condo they showed us because it was perfect. They also helped us expedite all of the paperwork very quickly because we we're up against a very tight deadline. It all worked out perfectly because we worked with them!"

"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."
