Perspective. Performance. Personality.

The Sparrow Team listens to what you want and offers options to achieve this as you consider major decisions like mortgages, insurance policies, and savings strategies.

We offer a relaxed, informative conversation, not a pitch. In fact, when we meet, you're going to talk more than we will.

We also offer perspective. Our collective expertise in mortgages, insurance policies, and savings options helps us see your whole picture and puts us in a better position to help you build the future you want.

After many years in the business, we understand that this is a big deal for you. Whether you're buying a home, protecting your family, or planning for the future, these are some of the biggest financial decisions you will make.

There are many different options out there. We shop the market for you for the products that best fit your circumstances. We're going to ask you a lot of questions. We're going to help you understand the options. And if you have any doubts or lingering questions, we're going to take the pen out of your hand until it all feels right for you.

I love my work because I believe in the importance of helping people get educated about insurance policies and mortgages before they make their decisions. I was attracted to this business because I love the challenge of making complex transactions easier to understand.


My clients can expect me to answer all of their questions in simple terms and make the entire process easy and enjoyable. My clients will get the most professional information about all of their insurance and mortgage options so I can put the absolute best plan together for them. No pressure, no fees for my service, no worries!


Golf, spending time with friends and family, and losing at fantasy football.

Brittany Gietz


Hello! My name is Brittany Gietz and I am a mortgage specialist on the Sparrow Team at Castle Mortgage Group.

As a mortgage specialist, it is my job to make your life easier and less stressful as you navigate through a complicated mortgage transaction. Whether you are buying a home, renewing or refinancing, I am here to listen to what you want and offer options to achieve those goals. I have access to many mortgage products at lower rates available from any bank, credit union or competing mortgage brokerage. I guarantee you the best mortgage deal in the marketplace.

As a working mother who has been through this process a few times now personally, I completely understand how challenging it can be to make time in your busy schedule to learn about all your mortgage options. For that reason, I am available to meet with you outside of normal business hours when it works for you!

I look forward to working with you in the near future!
