Sean got us financed for our first home after everybody else told us it couldn't be done. He guided us through the process and all the twists and turns, and helped us confidently navigate a really challenging market. Can't recommend him highly enough.

Really advocated for us to get what we needed, engaged and available pretty much 24/7 and pointed us to other resources like home insurance etc. Took good care of us.
Sean was friendly, efficient, skilled, concise and met every deadline while ensuring all involved in the process did as well. He also has a fun sense of humor which helped navigate my 1st home purchase/loan. He and his partner David work seemlessly! Highly recommend them!

We had an excellent loan process with Sean. It was our first 1031 exchange, and the paperwork was getting overwhelming, but Sean was able to keep us relaxed and focused on all of the 1031 processes, and our loan finalized, and we are very pleased, and would recommend Sean to anyone who is looking for a positive loan experience.

I highly recommend Sean to help with all of your loan and refinance needs. He knows the rate market superbly well and is an excellent strategist to get the lowest possible interest rate. Importantly, Sean stayed in contact throughout the process and was readily available to answer questions.

Sean started working with us in 2022 to obtain a loan to buy out our co-owner of our San Francisco home. He obtained us a jumbo loan with great interest (given the market ) and we bought out the co-owners interest and sold the property. We used him again during our search and final purchase of a new home. The process of finding a new home was grueling given not only the interest rate but the insurance situation as well. I could not have asked for a better agent than Sean. He kept our pre approval alive through several unsuccessful attempts to buy home and he was so responsive to our inquiries that I thought he must never sleep! He dealt with all the bumps with calm competence and always came up with a workable solution. He is incredible!

From the moment we started talking to Sean, I could tell we were in good hands. Sean is an amazing coach throughout the mortgage loan process – from making the offer all the way through closing. At every step, Sean supported us. He is proactive, knowledgeable, and so on top of it! Sean went above and beyond. Such a great partner to work with and we highly recommend Sean to anyone seeking a mortgage loan.

Sean's exceptional performance truly made our home-buying experience outstanding. His unwavering commitment and swift actions played a pivotal role in securing the home of our dreams. Without his dedication and tireless efforts, we might have missed out on this incredible opportunity. The speed at which we were able to close is a testament to Sean's persistence and hard work. We are immensely grateful for his professionalism and expertise, and we wholeheartedly recommend his services to anyone in search of a dedicated and efficient real estate professional. Five stars doesn't seem enough to express our appreciation for Sean's remarkable contribution to our home-buying success.
