Meet Our Team

Tyler Johnson
Principal Agent

I have worked in the insurance industry for 17 years, 15 of those as an Agency Owner for Allstate. I was born and raised in Walnut Creek in an Allstate family and took over the family business after my dad retired as an Allstate agent in 2001.

The most rewarding thing we do is being counted on a trusted advisor to our clients to see them through their insurance and financial needs. I’m a huge sports fan and follow all of our local teams. When I’m not working, I’ll be spending time with my wife and two young kids. After graduating college, a friend and I travelled across the country one summer and attended a baseball game in every major league baseball stadium.

Our family has worked closely with families and businesses for years to help people with their insurance needs – from homes to auto to boats and more. Our quality, service-oriented agency is not only owned and operated by a family, customers tell us we make them feel like family too.

We understand customers have a lot of choices when deciding how to protect what matters to them — from the company they work with to picking the right coverage. Our role is to provide information that helps you make the right decisions for your needs. We’ll start by asking questions to gain an understanding of what your coverage needs may be, and we’ll be there along the way to answer any questions you may have. Our goal is to guide you to the coverage that leaves you feeling confident.

Katie Dionne
Office Manager

I was born in Walnut Creek and grew up in Concord. I have had my insurance license since the year 2000 and obtained my Life & Health license in 2015.

I’ve worked with Tyler Johnson since 2001 when he took over his father’s business. What excites me most about my position is working with families in our community who are just like my own and being able to offer them great coverage.

Personally, I’m really passionate about animals. That’s why whenever I’m not working, you can find me at Contra Costa Animal services volunteering my time helping homeless animals into their forever homes or helping with their enrichment while at the shelter.

Something interesting that people might not know about me is that I work out regularly and enjoy participating in race events throughout the year.

Johnette Dionne
Licensed Sales Producer

I am licensed in property & casualty insurance and have worked in this office for 20 years. I have lived in the Concord/Walnut Creek area all my life. I am a member of the Contra Costa Blue Star Moms Chapter 20.

I have been working here 20 year, so I have a very long history with our clients and they depend on me. I love helping our new “out of state” clients get settled into Bay Area life. I enjoy taking road trips to visit family & friends.

I love talking about my dogs, a golden retriever and a golden doodle, working on my house and I love spending weekends cooking and trying out new recipes.

I love playing video games. I also attend the Avon Breast Cancer walk every year to support Kathleen’s Krusaders walking in memory of my sister.

Carol Jackson
Licensed Sales Producer

I grew up on the East Coast but moved to California with my husband when we were both young. My husband and I are both veterans.

When it comes to insurance, I’ve worked in the field for over 20 years in various offices. I always like to make sure that customers understand the coverages that they are buying. Especially young people.

I currently have 6 grandchildren and one more on the way. When I am not busy with them, I love to travel.

My favorite weekend activity is to take road trips with my husband

Boo Mariano-Junqueiro
Licensed Sales Producer

I was born and raised in Tracy but have predominantly worked in the Bay Area for many years. I love living in what used to be a” small town” but working in larger cities.

I started work in Insurance as an Account Manager at a TPA, then obtained my Life and Health License.  I then pursued my Property and Casualty license and joined Tyler Johnson Agency.

What excites me most about my role is connecting with people and the community. Working in this industry gives me the opportunity to help people make informed choices about their insurance needs that help protect them and their future. That connection is rewarding! Being more of a people person, I enjoy all the friendships I make along the way and being on the go with them.

Outside of work, I enjoy volunteering and when I’m not doing that I love going to the beach, shopping or wine tasting with friends on the weekends. I really enjoy spending time with my friends babies and young children. My boys are grown so its so much fun to see the little ones grow.

I also volunteer at my church in our children’s ministry program, our Mom’s program and for 2 non-profit organizations that my friends have organized.

Justina Perez
License Sales Producer

I was born in Walnut Creek and grew up in Concord. I love the area and the communities we serve.

I joined the Tyler Johnson Agency family and received my insurance license in November 2018. What I look forward to the most while at work is being able to provide the best products and services to protect our clients. I’m also excited about working, learning, and growing alongside truly amazing and talented people here at Tyler Johnson Agency. I am also bi-lingual and can assist you in both English and Spanish. llámeme para obtener ayuda con cualquiera de tus necesidades de cobertura de seguro

When I’m not at work, I enjoy spending time with my four-year-old daughter and supporting her through the love she has for karate. I also enjoy staying active and going to the gym.

Jim Galinsky
Personal Financial Representative

I have been working in the insurance business since 1997, specializing in the personal finance side of the business. I grew up in a small town on the edge of the Adirondack Mountains in New York State. My undergraduate studies began at Syracuse University and were completed at the University of Houston after a few years of break.

I most enjoy working with individuals and couples to solve their pressing financial need. I really like finding the key to creating a successful outcome for my clients, whether it is in selecting their life insurance, investment portfolio, or other aspect to the financial plan.

I enjoy spending my free time with my long-term life partner Mary Tuchscherer out in the various towns of the east bay enjoying shopping, a casual meal, or a movie. My guilty pleasure is to play poker at one of the local card rooms. My partner Mary created and manages a non-profit called VoiceFlame and I enjoy assisting her with that in any way that I can.
