Diana Hernandez
Agency Manager

I’m from Chicago and have been in the insurance field since 2001. I enjoy working closely with customers to help design a complete insurance portfolio to best suit their unique needs.

What excites me most about my role here at Tunnell Insurance Agency is learning about my customers and their insurance needs. Delivering excellent customer service is my priority.

On a more personal note, I really enjoy spending time with my family. I have 3 awesome boys, and I love being involved in their sports activities. I am definitely their #1 soccer fan. On weekends, we like to spend quality time with each other by doing fun family activities together!

Mariana Espinoza
Licensed Agent

I grew up on the north side of Chicago and have lived here for 28 years.

When it comes to my experience, I have been working in the industry since 2011. One of the things that I am most proud of is making sure that my customers are properly covered and have a clear understanding of their coverages and insurance needs.

Personally, I love spending quality time with my family and friends. Other then insurance, I can’t stop talking about my daughter. I also have a passion for interior design, creating unique home décor DIY projects. I also enjoy dancing.

On the weekends you can find me in the mall, park, restaurants, or at a friend or family’s house having a great time.

Daniela Larrain
Licensed Agent

I was born in Lima, Peru. I moved to Chicago at the age of 5 and lived in the city until I was 12. Our family and I moved to Antioch and that’s where I remember growing up.

The insurance industry has allowed me to utilize my unique background, training, and experience to help people secure the proper insurance that best suits their needs. I truly enjoy this town and as an active resident of this community, I value building strong connections to ensure the people that I help have peace of mind to thrive.

In my personal time, I love to spend time with family. One thing we highly enjoy doing together is building puzzles and going on adventures! Something many people don’t know about me is that I love to bake! So feel free to ask me what my latest creation was.

Marc Fillion

I grew up in central Connecticut, and I have a BA in Communications and Theater Arts. Early in my career I studied in Los Angeles and worked for a Hollywood production company. In 2007 I became interested in the insurance industry, and since then I’ve worked in sales, service, and training.

Insurance is the safety net we are all happy to have when we need it, and I’m happy to provide my customers with products that will meet their needs and help them feel confident for the future.

For fun, I love playing Ultimate Frisbee & Spikeball, and I’ve been known to participate in stand-up comedy and improv, with a wide repertoire of close-up card tricks. I’m also a huge Boston sports fan, and I’m fanatic about Star Wars (Particularly the original movies and the extended universe!) You’ll often find me hiking in the woods, relaxing at the beach, or playing board games with my friends and family.

Jenna Lee
Licensed Sales Agent

I was born in West Allis, Wisconsin, but, I was raised in Northbrook, IL. I’ve been working in the insurance industry for quite a bit now and what most excited me about my work is listening to individuals’ life stories.

Personally, I enjoy planning out my life through travel; and I want to learn about other people’s cultures. You can find me out with friends during the weekends living my best life! Regarding volunteer work, I am very supportive of the Feed My Staving Children food packing.

Destinee Oaks

Destinee started out in a car dealership and left to join an awesome agency owned by a former marine Eric Brown. She once saved a client’s life just by writing to her thanking her for her time and business.

Destinee grew up in Clearwater Florida and lived near the beach her whole life. Being close to nature encouraged her to become part of the world wildlife fund as an ambassador. She’s also passionate about her love for Jesus and loves to sing and dance.

Besides work, Destinee loves to get together with her family to go fishing on the lake. She’s a fun-loving person and always finds a way of making someone’s day a little brighter!
