The service and attention to detail from the John Santorineos team including Souzy Grammatis and Carrie Anderson was incredible. I always felt informed of what was going on and the transparency and ease of the underwriting process was a nice surprise. Really trust this team.

We have been shopping about refinancing and found many agents who push you into locking the rates asap. But John S. was very nice and very informative and didnt rush us at all. Also very very deatail oriented and sent us details everyday helping us make decision easier and logical.

John Santorineos and his team were fantastic! This is my fourth closing with John (two sales and two refinances) and he made the process painless and quick. John clearly articulated all our options and walked us through the closing steps. Souzy Grammatis made sure all the tees were crossed and ensured we stayed on track. John and Souzy gave us regular updates and explained where we were in the process.

These folks simply know what they are doing! Their experience accompanied by their knowledge and commitment to meeting client needs was very impressive. Were very flexible and offered a better rate. John Santorineos was simply great and I confided in him and his suggestions, which you can tell were very honest and he was looking out to get you the best rate based on my needs

John Santorineos is very knowledgeable and shares everything in detail, which makes the process even easier and smoother. He was very attentive and made sure that we understood every single aspect of the whole lending process, which was imperative for myself as a first time home buyer. More importantly, his responsiveness and timeliness with everything was beyond impressive. I can see why folks love to work with him and will certainly recommend folks to him.

John Santorineos and his team (i.e. Souzy Grammatis) were extremely helpful and a pleasure to work with. John and his team made this a painless process. I have worked with John Santorineos multiple times over the past several years and each time I have had a pleasant experience. John Santorineos and his staff make the process easy and are very responsive to my questions.

He takes care of all customers- no matter what type of loan you are looking for. He treated us all with the upmost respect and helped guide us through our situation. He was clear and precise and very friendly. It is the relationship that develops that will bring people back to the same company. The follow through and guidance from John and Suzy and Guaranteed Rate was the reason we would come back and work with you again. The service and attention to the customer was superb!

My whole family now uses them and will continue to use them further down the road. They treat you like family and have only your BEST interests at heart.
