Insider Info

Mentorship is not just a feel-good idea, it is a measurable difference-maker. According to Big Brothers Big Sisters of Central Arizona, Littles in its programs are 46% less likely to begin using illegal drugs, 27% less likely to begin using alcohol, 52% less likely to skip school, 37% less likely to skip class, and 33% less likely to hit someone compared with youth not in BBBS programs. In other words, a few hours of showing up can help shape choices, confidence, and futures in a big way.

In Arizona, generosity is more than a value; it is a way of life. From boardrooms to classrooms, ballfields to volunteer service, countless individuals give their time and energy to strengthen the communities they call home. This weekly #MissionMonday column shines a light on those difference-makers, spotlighting philanthropic leaders and volunteers whose passion for service is creating real, lasting impact across the state.

Today, we welcome Jacob Leih, a Big Brother with Big Brothers Big Sisters of Central Arizona. Through the program, Leih serves as a mentor, role model, and steady support system for his Little, building trust through shared experiences, honest conversations, and plenty of active adventures along the way.

How did you get involved with Big Brothers Big Sisters of Central Arizona?

I first got involved because I was looking for something meaningful outside of work. At the time, my job was causing a tremendous amount of stress, and that was affecting my personal life and relationships. I wanted an outlet where I could focus my time and attention on something bigger than myself.

The program ended up filling a role in my life I did not realize I needed. It gave me a way to positively impact the local community while also connecting with someone who may be going through hard times.

Why is this mission important to you?

Growing up, I did not have a strong sibling bond. My brother was five years older than me, my parents divorced when I was young, and I rarely saw my father. I was raised mostly by my mother and sister, and my sister became the sibling I could lean on.

I lost my sister to suicide in my late 20s, which was one of the most difficult times of my life. It caused me to withdraw from friends and family for years. Looking back, I often wonder how things might have been different if she had someone she could truly open up to during that time.

This mission matters because there are kids who need someone to laugh with, cry with, talk to, and trust. Having a role model, mentor, brother, or friend can change the trajectory of someone’s life. After five years in this program, I have seen how much of a difference that kind of relationship can make.

What does your volunteer role entail?

To me, being a Big means being a foundational part of a young person’s life. It means showing up, offering guidance, and being the best support system I can be.

Sometimes we go rock climbing, walk around the mall, attend program events, or do anything sports-related since we are both very active. But some of the most meaningful moments happen in the car, when he is talking to me about school, home life, or personal concerns. Those conversations give me a chance to listen, share perspective, and help guide him.

I think the goal of being a Big is to listen, learn, and grow. Listen to what your Little is really telling you. Learn who they are, what they love, what they fear, and what brings them joy. Growth happens naturally once trust is built and shared experiences begin to shape the relationship.

What is the mission of Big Brothers Big Sisters of Central Arizona?

To me, the mission is simple: Be the change you want to see in someone’s eyes. We all have moments where we wonder what we could have done differently when we were younger. As a Big, you have the chance to use those lessons to help someone else.

What has surprised you most about your experience?

I have been most surprised by how valuable time together can be, no matter how much or how little it is. There is a misconception that you need a huge amount of time to make a difference, and that can keep people from volunteering. You do not. Even 20 minutes once a week or a few times a month can matter deeply to a child who just wants someone to trust and confide in.

What is one of the most rewarding parts of your volunteer work?

Building trust. My Little and I were fortunate to develop a strong bond early, but that is not always the case. Sometimes it takes months or even years. Once you have that trust, you do everything you can to protect and nurture it. That is the most fulfilling part of being a Big.

What makes this organization stand out to you?

Big Brothers Big Sisters of Central Arizona works incredibly hard to match children with caring mentors. The organization does a great job showing how small moments can create big change.

As a Big, you may get to watch a child graduate elementary school, middle school, or even high school. You can be part of their journey. Many Littles also get access to experiences they may not otherwise have, from Spring Training and flag football to career-development opportunities. It is truly a joy to witness and be part of that growth.

Are there any upcoming events or initiatives you are especially excited about?

Phoenix Fan Fusion is coming up, and I will be hosting a table for three days to talk about the program. My goal is to get people excited about what Big Brothers Big Sisters does and how we do it. Sometimes all it takes is five minutes to help someone understand why they should consider getting involved.

If your volunteer work had a theme song, what would it be?

“Man in the Mirror” by Michael Jackson. We are often our own worst critics, and sometimes you need to step back and recognize the good you are doing and the change that can happen over time.

What do you like to do in your free time?

I am a big fan of rock climbing, which is also one of my favorite things to do with my Little. It is a great way to stay active, and it allows me to beat a 15-year-old in a footrace at the ripe age of 36.

I also enjoy playing Dungeons and Dragons with friends. It is a great creative outlet because I love storytelling and writing. My girlfriend and I also go to the theater most Sundays, which has become our little ritual before the start of a new week.

Where are your favorite places to go in the Valley?

Tempe Bouldering Project is one of my favorite spots. It is great for bouldering, working out, and bonding with my Little. Chipotle usually follows, where we eat giant burritos until we are sick to our stomachs.
