Meet the men and women who will be actively engaging your learners with hands-on learning.

A refreshing approach

We Know How to Make Learning Both Fun and Effective For Students

Supported by the latest in technology and cognitive science, we move beyond the traditional tools of lectures, homework, high-stakes tests, and grades. At Generations Academy, our learners learn in collaborative environments of multi-age learners. Our flexible approach challenges each learner with their differentiated learning plan, coupled with real-world projects and experiences.

Above all else, each learner that enters our doors begins a journey to discover their unique gifts and passions, and how they can be used to find a calling that will change the world.

Meet Our Team

We’re all working together to bring out the very best in our learners!



Elementary ages

My name is David Yentsch. I am married to my wife, Jessica, and together we are raising five learners. In addition to raising learners, we are doing our best to raise cows, pigs, turkeys, ducks, chickens, and rabbits along with fruits and vegetables.  We have homeschooled our  learners, with much learning occurring by way of living everyday life on the homestead.


While I have of course focused on teaching my own learners, I have also taught in many settings, including private pre-schools, public elementary schools, and also online teaching English to Chinese learners.


I love to play games, work, make music, read, eat the fruits of our labor on the homestead, and spend time with my family and friends.  I look forward to teaching and learning along with everyone involved with Generations Academy!

Middle School

My name is Brady Haas, and I currently live in Chippewa Falls with my wife and 3 young learners. We just relocated here after moving from Nashville, TN a year ago. I have been a teacher for the last 7 years, and am incredibly excited to step into the role of Guide at Generations. I love all things adventure, and getting to discover the depths of who God is and who He has made us to be in the midst of it.
Most of my time is spent with my family– we love swimming, going for walks, bike rides, and hikes. Personally, I really enjoying playing Ultimate Frisbee and learning how to fix things (even though I’m not that great at it!)
I am looking forward to cultivating meaningful connections with all of my learners at Generations, learning from each other, and growing together.

High School

My name is Erika Ehrhard and I’m excited to be part of Generations Academy. I graduated from UWEC in 2002 with a Masters of Science in Communication Sciences and Disorders. After graduating, I worked for both MJ Care and SPOTS HOUSE, providing speech and language therapy services through the Eau Claire and Chippewa County Birth-to-Three program. I loved that this job allowed me the opportunity to work alongside and support parents and caregivers in helping their kids take steps in their speech and language development.

In 2012, I transitioned out of my position as a speech-language pathologist into full time learners’s ministry through Jacob’s Well church. Again, I had the opportunity to partner with parents and caregivers to help kids take next steps; however, this time, it was next steps in their learners’s spiritual development. During my time in this position, I loved being able to collaborate in writing and developing curriculum, teaching learners of all ages, and developing tools and resources for parents to equip them to be spiritual champions in their homes.

I currently live here in Eau Claire with my husband, Jeff, and my two boys, Ethan and Adam. In my free time, I love hiking, playing pickle ball, playing board games with my family and reading a good book! I’m excited to be part of this school and l look forward to what God has ahead.
