Kellan Gregory recommends Aisling Ferguson

Aisling over delivers yet again! This purchase was particularly complex since my partner and I were both leveraging our finances to acquire our new home. Aisling was able to secure us the appropriate loan with a lower interest rate under a particularly short escrow. Communication was easy and Aisling was there whenever we had questions. You really feel like you have a champion working with you - highly recommend!

Will Gilbert recommends Guy Rivera

Aston patterner/ fitness consultant

Guy came highly recommended as a knowledgeable and experienced broker. Another broker recommended him who is a competitor.
My husband and I were pleased both with Guy and his staff.

John Joyce, Asa and their team are fantastic. They are always on top of our applications, information and process, and keep us informed and in the loop. We are very happy with their performance in all aspects of the finance and re-finance of our properties, from construction, to conventional lending to hard money for those niche occasions.

Thank you.

Catalina Appelblom recommends John Joyce

Catalina

John and his team were absolutely incredible !!! They were pleasant , professional and extremely competent. They did everything in their power to lock in the best interest rate and affordable monthly payments - including contacting the credit agencies on my behalf to fix any discrepancies .

Rob McLaughlin recommends Foster Weeks

My husband and I recently completed a purchase of our first home, and we couldn't have been happier with the work that Foster did on our behalf. Every question we had (there were many) was answered thoroughly yet clearly by Foster. He was very supportive throughout the whole process and kept us up-to-date on everything that was happening with our loan. We felt confident throughout the whole process that we were working with someone who was at the top of his game. On top of all that, Foster is a super-nice guy who is easy to talk to.

Molly Krause recommends Alan Kirth

He was amazing. He went above and beyond again and again. He didn’t let anything stand in his way. I highly recommend him.

Michelle Barden recommends John Joyce

Michelle Barden

John and Asa are a phenomenal team. They were there for us every step of the way. We have used them multiple times. Highly recommend!!!!!

Michelle Murre recommends Sean Maley

Founder, Azurine Travel

Working with Sean and his team has been incredible. It was our first time getting a mortgage and Sean walked me through step by step, advising and explaining all as we went. He got us an excellent rate and I look forward to working with him for years should we need to refinance or purchase a second home. Even our title company in Napa called Sean a 'dynamo' and said he was one of the most proactive and detailed mortgage brokers they've ever worked with. I cannot recommend Sean more highly!

John Osmer recommends Rich Polonsky

CFO

Rich Polonsky is amazing. I have lost count of how many mortgages he has done for us over the last 20 years. The process is by nature a pain. But Rich is expert and anticipating and navigating the things that can slow it down or make it frustrating. Our borrower profiles are non-cookie-cutter – we are self-employed entrepreneurs. Some of our properties have been non-standard also. Rich has always taken our borrowing curve-balls and knocked them out of the park. And his personal motto, “I work for you, not the bank” rings true every step of the way. I recommend Rich to anyone looking to finance or refinance their property.

Absolutely stellar service!! Thank you Guy Rivera!!!

Chris Diehl recommends Aisling Ferguson

Put simply, Aisling made it possible for me to purchase a beautiful home in the East Bay after a very lengthy search. With the quick turnaround required for closing and the complexity of my situation due to being an entrepreneur, there were a ton of hurdles to clear in a very compressed timeline. Aisling went the extra mile to get it done and I am deeply grateful for her extraordinary efforts! It's not clear it would have happened any other way.

giuseppe sircana recommends James W. Argo

President of engineering design and construction company

Easy review for me here: James and his team helped me about 1 year ago to obtain a loan for my own house; that went just quick and easy so, when I recently found myself in need of a loan for an office space for my company, I certainly had not to shop around. One more time James and his team handled my application professionally; I was educated and informed through all steps and everything went smooth and quick.
Thank you again!
