Working with Andrew Ashmore and his team at Sunflower Bank on my mortgage loan has been an outstanding experience from start to finish. In terms of potential lenders, I had three options at the beginning, but then I decided to go with Andrew and Sunflower Bank as I entered the contract phase, and that was the best decision. Andrew was incredibly helpful throughout the entire process—always patient, always clear, and always making sure we understood every step. His communication was exceptional; he responded quickly to every question and kept us fully aligned at each stage of the loan process. What I appreciated most was how Andrew made everything feel smooth and stress-free. He took the time to explain our options, checked in regularly, and ensured there were no surprises along the way. It truly felt like he was on our side, looking out for our best interests. Thanks to Andrew and his team, securing our mortgage was efficient, transparent, and reassuring. I highly recommend him to anyone looking for a loan officer who is professional, responsive, and genuinely committed to helping their clients succeed.
