Who We Are

Who We Are

ST Insurance Group is a commercial lines specialty insurance agency. We work with businesses just like yours ranging from owner operator businesses all the way up to corporations with 100+ employees. Our goal as your insurance provider is to form a strong working relationship together and to really get to know your business. We firmly believe that no two businesses are exactly alike so we work to understand your unique needs for business insurance. We take pride in our ability to educate our clients and to make insurance less stressful for you.

We began in 2016 as a part of our Family’s agency, Timmons Insurance Group, and in 2020 we made the decision to branch off and form an agency that focused solely on working with business owner’s. We have maintained our relationship with Timmons Insurance so that they can provide our client’s with top notch personal lines service, while we can focus on serving your business with our commercial insurance expertise.

We are headquartered in Central Texas just outside of Austin and service clients across the state. We have a passion for being involved in our communities and supporting the businesses we work with on a daily basis through involvement in our local Chambers of Commerce, School Districts, Economic Development Committees, and many other service based organizations.

We look forward to serving and getting to know you and your business.
