Aisling once again hit it out of the park in terms of the incredible service she provided in getting us a mortgage for our new home. She deftly helps everyone navigate a very complicated system, and is tenacious in solving any obstacle that might get in your way. Don’t think about going anywhere else for a mortgage. She’s the best!

Darolyn Davis recommends Ken Dean

I would recommend Ken to anyone who is seriously looking for a home loan. I have worked with Ken on several home loans. He has made this daunting process so much easier. He is efficient, thorough, patient and helpful. He’ll tell you exactly what is needed and guide you through every step along the way. Most importantly we will find you the best most cost efficient loan available. I really appreciate the fact that he will shop around to find the loan that finds your needs.

Ravi Malhotra recommends Aisling Ferguson

Real Estate Agent with Zephyr Real Estate

I just closed a deal with Aisling Ferguson. I have been selling real estate for 20 years and working with Aisling was one of the best experiences I have had. She is extremely diligent and professional. She is focused on the client's needs and offered a high touch level of service. I never had to wonder about the progress of our clients loan as she was prompt to respond to questions and kept me well updated throughout the process. I hope I have the pleasure of working with her again in the future.

Allison Hyde recommends Kathy Derangi

Bilingual Resource Teacher

We called Kathy for help with a refinance that we need for a remodeling project. Kathy sprang into action immediately and walked us through every step with meticulous attention to detail. She found us a 30-year fixed at a better interest rate than we previously had. Kathy was always available and responded immediately to our queries. Thanks to Kathy's hard work, we were able to accomplish our goals before taking off for a long trip.

From the first phone call we had, I knew We were in good hands. Ken has the confidence that he will make it happen. It’s settling to know he actually can.

Aisling did simply superb work on my behalf, in securing favored terms for my home loan in August 2017 when making a purchase in Palm Springs.

She is super responsive and informed, kept me posted during all of the stages of the pre-approval and loan funding, plus she keeps in touch regularly with informative updates.

I recommend Aisling without reservation.
