About Sean
Have you ever made a big decision but weren’t sure if you were getting the best advice? We want someone who understands our needs, but can also translate things into everyday language. It’s our philosophy that Good People deserve Great Advice. I’m a teacher at heart. My goal is to guide you through an outstanding mortgage experience that’s more of a relationship than a transaction. I enjoy making complicated things easy to understand. Real estate and home ownership is an incredible opportunity in our area – getting the right team around you to make informed decisions can be life changing. You can find my wife Kaylene and our FIVE kids hanging around Snohomish. We’re a little rowdy. When you’re ready to get started on a new loan – email, call, or text anytime

Sean and his team are nothing short of professional. They made the home buying process easy and as stress free as possible. They kept us informed every step of the way and there to answer any questions we had.

From beginning to end, Sean was a great partner with us. He spent time before we were ever a customer helping us understand the various borrowing options we had so we could understand what our flexibility would do for us. Then when we were engaged on an actual house, he helped us apply our options creatively, even walking us through one option where the money could come from a non-traditional path which would result in Lower Mortgage not even having a part to play. When someone is willing to help you, and NOT make money, that's a level of support one rarely sees. In the end, we used a traditional loan for the property we purchased, and he found us a really great rate (not trivial considering some of the aspects of the home). We'll end up doing a major refinance in 1-2 years after a deep remodel is complete and we've sold our other property, and we absolutely will work with Sean and the team again for that "final" loan.

is a true professional that I can always rely on. I called him with a very short time span in which to close on a house and he made it happen!
