Welcome to
GSA Business Services
Our mission is simple: to educate, support, and empower our clients every step of the way.
About Us & Who We Are
Welcome to GSA Business Services, where personalized service, trusted expertise, and community care come first.
My name is Shannon Addington, and I am the proud owner and operator of GSA Business Services in Mont Belvieu, Texas. What began as a dream four years ago alongside my husband, Glen, has grown into a family-owned and operated business dedicated to serving individuals, families, and businesses in our community.
With over 15 years of experience in the tax industry, I am passionate about helping clients navigate tax season with confidence and peace of mind. Our goal is not only to prepare accurate tax returns, but also to educate our clients on how taxes work so they never feel overwhelmed when tax time comes around.
At GSA Business Services, we take pride in sitting down with each and every client personally. We believe you are never just a number — by the end of our meeting, many clients feel more like old friends than customers.
As we continued serving our community, we recognized a growing need for additional financial services. This led us to expand into financial education and planning, helping clients better understand how money works, how to grow their wealth, and how to protect their families’ futures.

Shannon is the only person that I ever want to deal with for my taxes and business services. She is able to explain things to me that I’m not sure of, and I know she has extensive knowledge of the tax process, which is fabulous. I cannot thank her enough for her dedication and hard work that she does for me.

Shannon is the best. She has been helping us with our taxes for 3 years and assisted me with setting up my retirement plan. We trust her completely and highly recommend GSA Business Services for all your needs.

Thank you Shannon for being so amazing with your work! We truly couldn't recommend anyone better and trustworthy to do our taxes! She was very patient and knowledgeable and made the process of filing our taxes stress free and painless; which is not something we expected filing for our business!
