As a longtime resident of Arizona with a background in real estate mortgages and investing, I understand what it takes to “get the job done.” Customer service is my #1 priority and I have surrounded myself with an amazing team of knowledgeable and passionate people.

I work closely with my customers and realtor clients to make the best possible choice for their lending needs. This means that I listen to their concerns and what their future needs may be. I explain the process from beginning to end and make sure all of their questions are answered. When I begin working with a customer or real estate agent, it is extremely important to me that they know where we are in the process and that I am there for them to address any concerns or questions.

Customers come to me with different needs and it is my job to make sure that I do everything possible to help them realize their dream. I work hard for every customer and realtor that I work with and I am blessed with a staff that has the same commitment.

I am a former United States Marine and a retired Arizona State Police Officer. I take pride in everything I do and believe it is important to give back to the community you live in. I am on the Board of Directors for the Green Valley/Sahuarita Chamber of Commerce, and a member of American Business Women’s Association and Valley Business Networkers. I volunteer many hours to youth organizations in the Tucson area and enjoy spending time with family.

At Sunstreet Mortgage, I work with some of the top professionals in the industry. With in-house underwriting, and a support team that always strives for excellence, it is not hard to see why customers and realtors return again and again.

I look forward to working with you and establishing a long lasting relationship that you can count on for your future mortgage needs.

Just wanted to say Thank you again for the professionalism, friendliness and efficiency that you handled our mortgage.

Semper Fi and thank you

Dave Newman

Kim and Chris:

Just want to take a moment in my very big and exciting day, to thank you both for everything you have done. Thank you for your work and dedication, but most of all, for being patient and explaining all necessary and making this whole process a lot less painful.

I was at the new house a good part of the afternoon, just contemplating the mountain view and thanking God for this gift, also thanking my mom and making her part of this joyful day, but don’t want to forget you who help this become possible.

May our Lord bless you and keep you always,

Clara Aguilar

I just want to take a moment & thank you very much ….for making everything work out for the Pettys. I know you give all your clients outstanding service. The Pettys just happen to be very “special” to me. Thanks again!

I applied for and received a mortgage from Kim at Sunstreet Mortgage and I would highly recommend her as she is very knowledgeable, personable and will work with you to get the best financing available so that in the end you will be happy with your mortgage. She was a delight to work with and any questions or concerns that you have she will have an answer!


I received an immense hug on Sunday from my friend Margaret [..] for your help to them. She and Dick are such nice folks and although I did not get into details with them, you seem to have given them hope in their frustrating refinancing quest.

Thank you for being an outstanding lender and individual that I can send people to with no qualms! Hope you are having a good day!

I was very impressed with your class on reverse mortgages several months ago and now your professionalism in this transaction has tipped the scales in your favor. I would have sent you someone before this but have a large cash business and sometimes people have their own ideas on lenders. Then I have to live through their choices!

Sincerely, you obviously are a class act and you have got my confidence and all that goes with it.

Sunstreet Mortgage was professional and fast. We closed on our home in less than four weeks. We were very pleased with the service and particularly the thoroughness of the brokers involved in securing our mortgage.
