About Our Team


Shannon Galvin – Owner/Agent

I was born and raised in the Houston area where I became involved in hunter/jumpers at a young age and I have been riding ever since, competing mainly in the Southern U.S.

I received my Bachelors in Animal Science and my Masters in Equine Reproduction from Texas A&M University. During my education, I became very interested in equine medicine to include the reproductive process working for a few clinics in the area as well as internationally for an embryo transfer center in Holland.

My background, experiences and being a part of the equine community has helped me determine my career path. I am very proud to say that I chose the insurance and financial industry so I could serve the equine communities with which I share a passion for.

Ashley Aguilar – Sales Associate

I was born and raised in New Jersey.  I received a B.S. in Animal Science from University of Vermont then a M.S. in Equine Reproduction from Texas A&M University.  After meeting my husband and starting our family, Texas is definitely home.

I have been involved in many aspects of the horse industry – from growing up riding hunter/jumpers in NJ, driving Morgans in VT, to trying my hand at eventing and stock horses in Texas. I’ve worked for trainers, a tack store, and a commercial quarter horse breeding farm.

I’m excited to extend my career path into the financial and insurance industry.  I look forward to helping protect the investments that matter most to you.

Sarah S. Medina – Client Service Representative

I’m a retired from being a teacher for 32 years. I taught ESL, reading lab, and dyslexia classes for grades Pre-K to 5th. I believe I loved teaching 1st graders the most! I have a son, a daughter, and two lively grandsons. Working with Galvin Agency is a great way to keep my mind and fingers busy. I look forward to working with you!


Heidi Tidwell – Account Manager

I was born and raised in Bryan, TX and developed a passion for the Insurance Industry early on during my first agency Customer Service position held in High School. I received my Bachelors in Business Administration with a minor in Marketing from Sam Houston State University. I moved to Houston shortly after graduating and continued pursuing my career in Insurance working primarily with Small Business Owners in the Construction, Service, and Restaurant industries. I’m excited to pivot two decades of insurance product, service, and best-practices knowledge to the Equine Industry. We are proud to offer our clients the highest level of service and look forward to helping you protect what matters most!
