Orlando did a fantastic job securing a mortgage for my husband and I shopping for our first home. My husband is a solo investor, so his income is super complicated, and Orlando was able to shepherd us through the process and get us the loan we needed with a competitive rate. He was kind, empathetic, and super communicative. We would love to work with Orlando again one day and highly recommend him!

Joel was great to work with and we felt like we were in very competent hands with him. We appreciated his honesty and forthrightness, his availability and fast responses, and his ability to explain everything we needed to know about rates and points and closing costs in a way that didn’t make my eyes cross. His secure document upload site was easy to use. We had a short closing window and he managed to get everything lined up for us in plenty of time. Thanks Joel! We will recommend you to all our friends and family!

Jim and his team have extensive experience working with Bay Area homebuyers and have never hesitated to provide additional clarifications and guidance through the process. Jim is not only knowledgeable and efficient, he is always prepared- there are always Plans A and B available to ensure that we have the best chance of closing. As a first time homebuyer, I could not recommend Jim more as a broker who will get the deal done!

I cannot recommend Bob highly enough! As a first-time homebuyer, I was incredibly nervous about the mortgage process, but Bob made it smooth and stress-free. He was always available to answer my countless questions, responding to my emails promptly, even on weekends and late at night. His patience and dedication were truly remarkable. Bob didn't just process my loan; he genuinely guided me through the entire homebuying journey. He provided invaluable advice on when to lock in my rate, and even proactively alerted me to favorable market changes, helping me secure a fantastic rate. He was also incredibly efficient, working tirelessly to expedite the process without sacrificing any attention to detail. If you're looking for a knowledgeable, responsive, and genuinely caring mortgage lender, Bob is the person to call. He exceeded all my expectations, and I'm so grateful for his support.
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!

I had a great experience with Bob. He is very responsive to any questions that came up along the way, even as I considered other lenders. Bob ended up taking over my loan and was patient as I navigated some frustrating complications with another lender. As delays occurred, I was worried it would take too long to close, but he was able to work through unexpected changes and quick turnover times.
