“I have had the pleasure of using Kathleen Costanzo and Marina Sarabia of Keller Williams to sell over 200 Condominium Units in Broward County. As a developer and real estate investor, I have dealt with many real estate professionals throughout my career and I can say with confidence that Kathleen and Marina are The Best – a professional team that knows all the intricacies involved in real estate transactions. Most importantly they are able to get the job done and CLOSE DEALS!”

“I wanted to take a moment to thank you for being there for us every step of the way; your patience and time while searching for our home, the negotiations, inspections and finally the closing. Your experience made us aware of things we would have otherwise overlooked with a costly outcome. Your professionalism made the stressful process of buying a home, a very smooth experience with minimal complications to deal with. You truly made our dreams come true, we love our home!

Thank you very much for everything you did to make this happen!”

 Commitment to Excellence: “We suddenly found ourselves in a situation that demanded relocation of our family from St. Louis, Missouri to Fort Lauderdale, Florida with only 10 business days in which to complete this relocation. This situation is distressing enough for any family but ours is different as we have a special needs child and we needed everyone involved aware of how difficult this issue was critical to a successful relocation. Fortunately, our Real Estate Agent in St. Louis, Diane Freer, took it upon herself to screen and search out an agent in Fort Lauderdale area to work with us.

After a great effort on her part, she came back with one strong recommendation for an agent in Fort Lauderdale, Kathleen and Marina. We contacted them and were immediately impressed. Marina and Kathleen quickly reassured us that they would be able to work with our time frame and our family to find us the perfect home. They immediately put us in contact with a team of professionals to work towards loan commitment, securing insurance and title and closing preparation.

When we arrived, not only was our loan secured but Kathleen and Marina were more than prepared with properties to view. It only took two afternoons of looking to find a home we were pleased with but it would clearly not be easy deal to negotiate. Despite their best efforts to find us a vacant home, we were interested in a home occupied with a family that had five children, Marina and Kathleen convinced the seller’s agent that our offer was worth accepting in spite of the inconvenience and short notice involved.

This is when we really got to see exactly how experienced and skilled these two professionals are. Obstacles seemed to pop up constantly with this deal. Problems were found during the inspection, we had trouble finding an insurance agent willing to write a policy on the property, the sellers and their agent were difficult when trying to negotiate a fair agreement concerning roof leaks that were discovered and to top it off a $35,000 lean was discovered on the property only three days before closing.

We feel confident in saying that without Kathleen and Marina, this deal would have missed the closing date or fallen through completely. Thus leaving our family with our special needs son scrambling for a place to live as our home in St Louis was already sold and timing was critical. However,they systematically attacked each problem we encountered and would not accept “no”, “I cant’t” or “it isn’t possible” as an answer. They not only conquered every challenge  presented but prevented additional problems by negotiating cash back at the closing table for new damage found during the final walk through. Marina and Kathleen commitment to excellence and dedication to us as clients was unmistakable through this entire process.

It was a blessing to our family that Kathleen and Marina were our agents through this process. We feel very fortunate to have worked with them. Their extreme professionalism and commitment to excellence has earned our loyal business.”

“Having failed after two months in trying to sell our condominium ourselves, I received a call from Kathleen Costanzo who had read our advertisement describing our unit in “The Ocean Summit” on Galt Ocean Mile Drive. I had received innumerable calls from countless Realtors – both from other real estate companies. However, until I received Kathleen’s call, we were not interested in listing with a real estate company.

I was very impressed with Kathleen and Marina’s professional handling of the sale of our condominium. Working as a team in bringing potential buyers to view our home was a new approach to selling to me. And, I could see the advantages to this selling approach. They discreetly made suggestions on decorating changes, which opened our living/dining room areas to appear larger. They were very considerate in scheduling viewings of the unit. We were also pleased with the numbers of showings they had each week. Kathleen and Marina rank the best of sales representatives we have worked with in selling our homes. I feel we would be remiss should I not commend their outstanding sales efforts, as well as express our hearty thanks.”

Proven Experts In Pompano Beach


“We would like to say a big “thank you” to both of you for helping us find the most perfect vacation spot in Pompano Beach.
From the minute we met, Dave and I felt extremely comfortable. Your warmth, friendliness, experience and knowledge helped to lead us in the right direction. Thank you for being patient with us as we walked in and out of what seemed like “a million” condos. We knew what we wanted, but we just weren’t sure where to find it. It was most helpful to be able to have immediate contact with you by phone for answers to our questions.

After finding what we believe is the “perfect spot” for us, you help in securing a mortgage and all that follows was superb. You helped make the experience painless.

You both have proven to be experts in your field. We will not hesitate to recommend you to family and friends who are considering purchasing in that area.”

— Dave and Dawn Zeevalk


“I just wanted to applaud the excellent service we received from these two realtors. They were extremely professional and went the extra mile to ensure that our home sold in a timely manner. Kathleen and Marina impressed us provided us with constant and timely updates regarding activity on the house.

The time they spent marketing our home was evident in the fact that they had offers soon after the home was listed. Since we had a previous realtor who did not bring us one viable offer in five months, we learned the value in choosing a high caliber realtor. Kathleen and Marina are truly tops in their chosen field. We would strongly recommend their services to others!”
