Philip Ho recommends James W. Argo

Loan Recipient

Jim came highly recommended to us for our financing needs, and he did not disappoint. He is experienced and knowledgeable and is a pleasure to work with. Jim kept us informed every step of way on our loan process and strategically procured the best interest rate, with the lowest amount of associated fees. His combination of business savvy and availability made us feel extremely confident that our needs were top priority. We would definitely use him again for any future transaction.

Brent Piattelli recommends Ken Dean

Ken IS THE REASON WE GOT OUR HOUSE. He made everything happen that we needed him to, and the loan was not an easy one so I was very impressed with how good he is at his job both knowledgeable and fast-paced. I would recommend Ken to everyone!

Nancy Hawkins recommends Kathy Derangi

New homeowner

Kathy Derangi was really wonderful to work with every step of the way. I’m a first time home buyer and she was there to help me navigate the paperwork and documentation of credit worthiness at every juncture with a positive attitude and thoughtful manner. I would often get texts from her after her work hours which told me that she’s an incredibly dedicated person and works hard to get her customers the best possible deal. I don’t know if I would ever buy another house at this time in my life but I have to say that if I did, I certainly would want to do get my mortgage with Kathy.

Cathy Bryant recommends Kathy Derangi

Homeowner and Senior Escrow Officer

Kathy has handled my personal refinances for a number of years and I would highly recommend her for both purchases and refinances. She is quick to respond to questions, very professional and she gets the job done without a lot of back and forth requests. She knows my time is limited during the day so gives me a list of homework to do at night.

Shelley Viviani recommends Robin Patronik

Retired educator

Robin is exactly the person you’d want to guide you and your loan process. She is very detail oriented and familiar with an array of issues which may arise, and how to effectively, preemptively address them.
I’ve financed and refinanced numerous loans with her and my satisfaction rating for her is a 10 out of 10!!

Elaine P recommends Pov Oum

Program Manager

My realtor first introduced me to Pov two years ago during the purchase of my condo and I just recently worked with her a 2nd time to refinance my loans. Both times she has been amazing to work with! She knows the market well and provided me with different options and financial calculations to help me make the best decisions. Now that everything is online, we did most of the transaction via email, which works best for me since I am on conference calls and meetings all day, but I also knew that I could pick up the phone and call her anytime. Thank you Pov for helping me thru the process!

Neeraj recommends Pov Oum

Pov Oum helped to complete a refinance on my primary residence. Pov was helpful communicating the process and timing for each of the critical milestones. Due to the complexity of my file, she was extremely strategic on the approach while meeting my requirements from the transaction. I highly recommend her for any mortgage transaction. Thank you Pov, can’t thank you enough for the expertise and customer support!
