Local Allstate Agent: Meet Herminia Sitter

I've lived in the Woodlands/Spring area since 1996 and opened my Shenandoah agency in 2017. Before that, I lived in the city while attending the University of Houston, Go Coogs! I love the small-town feel this community has, even though it's a part of the metropolis that is Houston.

One thing you'll notice about my agency is that staying involved in the community is a priority for us. My agency regularly supports the Montgomery County Women’s Center and Woodlands Township with our time and resources. I've also served on the Houston Junior Chamber of Commerce Consular Ball committee, the John Cooper School's Gala and Signatures Author Series committees, as well as their Dragon Boosters Club.

I like having fun, which is why you'll catch my staff and I in a heated cornhole tournament if you stop by our office. When I'm not at work or out in the community, you'll probably find me watching college football with my husband, Mark, and daughter, Madeline, who is a cheerleader for the University of Texas Longhorns.

I became an Allstate representative because I wanted to build a legacy for my staff and family by doing what I love, helping local families protect what matters most to them. Whether you're a first-time home buyer in need of home insurance, or a motorcycle owner looking to protect your shiny, new toy, we can help. Stop by our office, play a round of cornhole and learn how we can help you prepare for the unexpected.

Local events & news

Supporting Sisterhood and Girls in Foster Care

Giving back to our community is a priority for my agency, and I'm proud to support Sisterhood, a nonprofit dedicated to helping girls in Texas' foster care system. I donated an air hockey table and basketball unit, which will be housed in their brand-new activity center where the girls can just be kids and have some fun. Thank you, Sisterhood, for letting me be part of something so special!

Supporting Safe Driving

Promoting safe driving habits is a priority for my agency. That's why I recently sponsored the Woodlands Township Neighborhood Watch's 2019 Tech Free 4 Me Driving Village Challenge. The challenge ran from February to October 2019 and encouraged drivers of the village association to earn points for driving tech free using the SAFE 2 SAVE app. The winning village association, College Park, received $1,000 for earning the most points for driving tech-free! Congratulations to our winner, and our two runners-up, Indian Springs and Creekside Park, for winning $700 and $300, respectively.

Celebrating 2 Years as an Allstate Agency

Monthly Income For Loved Ones

Bills come monthly. Your life insurance payout should, too. That’s why as your local Shenandoah Allstate agency owner I offer life insurance that pays out like a monthly paycheck.

Celebrating Our First Year Serving Shenandoah!

We’re proud to celebrate our first year serving the Shenandoah community as an Allstate agency! It has truly been a pleasure working with and getting to know so many of our neighbors. We’re looking forward to helping protect and educate you for many more years.

Support for Habitat for Habitat for Humanity of Montgomery County

Helping people is at the core of what our agency does, which is why we’re proud to support Habitat for Humanity of Montgomery County.
