Tammy Young

Executive Director

I joined BBBS as the Executive Director in October of 2014.  I have a Bachelor of Science in Elementary Education from UW – Oshkosh and have over 25 years of work experience focusing on sales and marketing with an emphasis on volunteer engagement.

Many people have heard me say, “I love my job!” Big Brothers Big Sisters is a program I am proud to be affiliated with as it directly impacts the lives of local children.  I became a Big Sister myself a little over a year ago and it’s THE BEST thing I have ever done.  Will you make time to make a difference today?

Jennifer Smith

Program Director

I have a Bachelor of Science degree in Psychology and an Associates degree in AODA Counseling. I enjoy working to keep the children in our program safe and happy. I keep in constant contact with all members of each match and keep accurate documentation to ensure that everyone involved in getting the most out of our program. I also plan and oversee all match activities for the organization, and I am always looking for fun ideas to keep our matches engaged!

Lisa Warntjes

School-Based Program Coordinator

I am the Enrollment & Match Specialist for the School Based Program at BBBS. I have a degree in Psychology and enjoy working with the variety of people I meet every day. My job is to recruit and screen high school students, college students and adult volunteers that will mentor a child during school hours. I keep in regular contact with each school based match, the child’s parents and teachers. It is rewarding to see how much a mentor can help improve a child’s attitude toward school and their relationships with both peers and adults.

Sara Straub

 Recruitment & Match Specialist

I earned a Bachelor’s Degree in Social Change and Development from UW-Green Bay and have twelve years of human services experience where I’ve developed a passion for helping children and families improve their lives.  “It is such meaningful work to nurture Big/Little relationships and support them as they have fun together and create lasting bonds.  Through regular contacts, I ensure the Big, the Little and Parent/Guardian are all having a safe & positive experience with the Big Brothers Big Sisters program.

I’m also very excited for my new role as Recruitment Specialist, which affords me the opportunity to connect with a variety of individuals & businesses to help spread the word about our BBBS mission and highlight ways people can get involved.”

My husband Chris and I live near Eden and have two children: Jackson, 11 years old and Becca 9 years old.

Jeanna Donovan

 Enrollment Specialist

I joined BBBS as the Enrollment Specialist in June of 2021.  I have a Bachelor of Science in Elementary Education from St. Norbert College and have six years of teaching experience and three years of non-profit experience as Literacy Coordinator matching tutors and students in an adult literacy program.

Working with children you realize the impact the individuals they interact with can make such a difference in their life. I am very excited and grateful to have this opportunity to meet our new Littles and Bigs as they enter our program and help them connect with someone who will make a positive, lasting impact – for both of them!

Jennifer Serrano

 Enrollment & Match Specialist

I am very excited to be a part of BBBS of Fond du Lac County as an Enrollment and Match Specialist, starting May of 2022.  I have an Administrative Assistant degree and previously worked 17 years in the insurance industry, taking a break to raise my children. During that time I volunteered frequently in the school system, with Girl Scouts, and had a leadership role with MOPS (Mothers of Preschool Students).

In my role at BBBS I will be helping Bigs and Littles to find their best match and following up with them as they get to know one another and grow in their relationship. I feel honored to play a part in making a difference in the lives of the Bigs and Littles in our program!

Jennifer Leu

Marketing & Development Specialist

I started at Big Brothers Big Sisters of Fond du Lac County as a part-time marketing specialist in January 2022, and joined the team as a full-time marketing and development specialist in May 2022. I received a bachelor’s degree in media studies and digital arts from the University of Wisconsin-Milwaukee in May 2020, and began working as the marketing specialist at Big Brothers Big Sisters of Washington County shortly after. Now, I’m happy to continue empowering youth through mentorship a little closer to home. Being able to hear and share match stories firsthand even led me to become a Big myself!

I grew up in Eden where I currently live and spend most of my time with my family, my dog, or a good book.
