I can't imagine what it would have been like to go through the process of buying my first home without Shirley Siao. Her patience, guidance, wisdom, and sense of humor. It was abundantly clear during the entire process that I was working with the best and smartest loan officer. I am very fortunate to have had this opportunity to work with Shirley, and I would gladly, and enthusiastically recommend Shirley to anyone and everyone. I would be honored to serve as a reference and talk to prospective clients about how great she is. There is no way for myself to express how much I appreciate the tremendous value of working with her. However, I will absolutely be working with a professional in Shirley again when the time comes to buy my next home.
