Bianca Guzman recommends Veronica Mora

Veronica is fantastic! She is patient and explains everything! Buying a home can be overwhelming, but she made the process easy and she always kept us informed. If anyone is looking to purchase I always recommend her.

Kevin Rooney recommends Marilee Breslin

Marilee is simply the best. She works diligently to obtain the best possible rates and is incredibly responsive. I wouldn’t even consider another broker.

Tom Sweeney recommends Kathy Derangi

Home Owner

I asked Kathy about a home equity line of credit and she recommended a home refi at a lower rate.
I have purchased and refinanced several homes over the decades and Kathy was great.
She communicated with me on a regular basis, some times two or three times a day.
She was professional, knowledgeable and friendly through the whole process.
I will use her again and highly recommend her.

Jeff Wong recommends Kathy Derangi

Environmental Health and Safety

I couldn't be happier and more thankful for the support and services Kathy provided to our family towards the purchase of our new home. Initially, she was very responsive and provided a clear table for what our purchase options were at various levels; this was immensly helpful for my wife and I in forecasting projected expenses. Once we got the ball rolling, Kathy was on top of it and was diligent in following up on critical items and providing reminders along the way which kept us on track. It was clear throughout the process that she had our best interests in mind. We will certainly be using Kathy again in the future and recommend her to anyone who is out there looking for a new house. Thanks for everything Kathy!

Jaime del Palacio recommends Sean Maley

Sean is awesome! I worked with him to secure my loan for my home. He was always very responsive and on top of things. Guided me through the process and made things go smooth. I would highly recommend him.

Edmond Meinfelder recommends Julie Malta

Software Engineer

Julie is one of the most organized and professional people I've ever worked with. I tried another mortgage broker and was confused from the start on what was happening. I quickly switched to Julie Malta based on the reviews and was pleased that my experience was better than I could have expected. To be fair, I put a lot fo work into the paperwork and followed her instructions to the letter. Though I felt I put a lot of work into the application, Julie put more and kept the process superlatively organized. There was not one point where I wondered, "What is going on?" Julie made a consistent and concerted effort to communicate with me, even when she was on vacation on the literal other side of the planet. I can't think of how she could have done a better job. I highly recommend her and would work with her again.

Sarah Lacy recommends Aisling Ferguson

CEO

Aisling has helped me out of nearly impossible mortgage situations twice. Her patience, attention to detail and resourcefulness are unparalleled. Everyone who has been part of these transactions has absolutely raves about her. I’ll never work with anyone else. It’s strange when you have more loyalty to a mortgage broker than, say, your hairdresser but that’s absolutely the case for me with Aisling!
Aug 7, 2019

Racelle LaMar recommends James W. Argo

Doctor of Veterinary Medicine

Wow. Jim and his team really went the extra mile for me. My loan was a bit 'out of the ordinary' and had quite a few moving parts.
Their ability to get the deal done was amazing, their communication outstanding, and I was quite pleased to work with them.
I recommend James W. Argo for your mortgage needs.
Aug 7, 2019

Yvette Fawzi recommends Mireille Costandi

We have done several loans/ refi with Mireille. She is thorough and meticulous and everything always goes smoothly. She works hard to do the very best for you. You are in good hands.
Aug 7, 2019

Julie Keshmiry recommends James W. Argo

Chief of Staff

A loan process can be unclear and painful but James expertly helped us navigate this. He was incredibly responsive, always on top of the meticulous steps. He also guided us with sound advice along the way. I would highly recommend him.
Aug 7, 2019

Anonymous recommends Kathy Derangi

Kathy was super organized, wonderful at breaking everything down for us and communicating, and overall easy to work with. Highly recommend her!
Aug 5, 2019

Max Dar recommends Guy Rivera

Happy Client

Guy is the absolute best out there. His attention to detail and knowledge of the entire industry, inside and out, is the mark of a true professional and a true rarity when combined with his steadfast loyalty and strong work ethic. Guy is also a patriot and takes tremendous care of our Veterans, doing a VA loan with him was easy and fast.

You will not find a better lender. Thank you Guy!

Paul Carr recommends Aisling Ferguson

To say Aisling did an amazing job is a huge understatement. When we called her we had just been let down by our previous broker right in the middle of trying to buy our dream house. Not only was Aisling able to get us the loan we needed, at a great rate, but she also dealt quickly and professionally with escrow, insurance and all the other parts of a complicated transaction. If you're buying a house in the Bay Area or any other part of California (we were in SF, but buying in Southern California) Aisling should be your first and only call. She will fight for you.

Don L. recommends James W. Argo

Attorney

Jim did a great job advising us and managing our situation which required some extra steps due to the July 4th holiday. Can't provide enough high praise about the level of professionalism and service one can expect from Jim.
Jul 22, 2019

Nancy recommends Rich Polonsky

Such a pleasure. I was guided through each step. Communication was superb! A gentleman and a delight.
Jul 22, 2019

Jennifer recommends Sahar Milani

Sahar Milani was a pleasure to work with. She went above and beyond and worked with us to resolve a few unforeseen financial matters that came to light during our loan process while purchasing our second home. With our existing property, she was able to refer us to the exact financial institution geared specific to HELOC and purchasing a second home. She is available to answer any question and was amazing to work with, I was never worried!
Jul 22, 2019

Diana recommends Fe David

Fe was great to work with. She made herself available any time of day to answer any questions. She kept me up to date throughout the entire process which was greatly appreciated.

Sally recommends Suzanne Diliberto

Suzanne was diligent and worked hard to get our refinancing completed. She kept us informed and followed up effectively. It was a pleasure to work with her.
