Our Leadership Team

Nate Barge

My name is Nate, and I’m proud to serve on the inaugural NODCC Board of Ambassadors. Diagnosed with complete ACC at birth, I became more aware of my condition around age seven and have since embraced advocacy and education through NODCC, which my family and I have been part of since 2001. The community has become like family to us, offering support, connection, and purpose. I’m passionate about helping others understand ACC and encouraging acceptance through shared experiences. Over the years, I’ve also spoken with families, professionals, and peers to help bridge the gap between lived experience and awareness. My advice to young ACCers and their families is to find a passion—mine was baseball. That love led me from playing and managing teams to earning a communications degree and now working in social media for Edgewood University’s baseball program.

Dennis Koenigs

Dennis Koenigs, shared, “Having a son with ACC, my wife and I have difficulty explaining the condition. Most people, even family, don’t “get it”. When we’re with people from the NODCC, they “get it”. It’s a family that is always there for you.” Dennis is now part of the board, because helping others find a community that “gets it” is important to him. Dennis became most involved with the NODCC around 2020 when his family needed contacts to assist them. His family needed to gain understanding about their son, Donovan, and his journey in ACC as he transitioned into adulthood. Dennis found the contacts he made through the NODCC to be indispensable. His family attended the Frisco and Chicago conferences, and Dennis soon realized the NODCC was an organization he would like to assist in its mission. As Dennis approaches retirement, I felt a need to “give back” to those that have helped his family, and the NODCC is one of those organizations. As a board member, he is excited to see increased membership and help to grow the group’s ability to contribute to research. To anyone considering getting involved with the NODCC, Dennis offers, “Don’t hesitate. The adage ‘many hands make for a light load’ comes to mind. We all have gifts to share and contributions to make.” When not busy being a board member, Dennis spends time with his four children and five grandchildren. He also enjoys hunting, fishing, and spending time outdoors, and working on projects around the house.

Kim Manning

Kim Manning is actually on her second round of board service, and this is because she has been a part of the NODCC dating back to 1999 when the very first email list was put out! She is a fixture in our NODCC community, and like Jyothish, her child is 26 years old! Kim’s son, Will, has hypoplasia of the Corpus Callosum. Her most treasured part of being the on the board thus far has been watching the organization grow and meeting other families. When asked what upcoming initiatives she’s excited about, Kim shares, “The new website and helping other families through these changing times.” We love Kim’s practical outlook when asked about the benefits of investing your time and energy into the NODCC. She shares, “The ability to have community in this journey far outweighs the minimal investment of time that may be asked of you.” We couldn’t agree more. Our community is unmatched! Kim would love for everyone to know about the research we invest into NODCC’s research avenues, and not only the community-related elements so many are familiar with. Kim’s future goals for the organization are making sure we can offer tools to navigate the various systems and programs intended to help. Kim’s once-upon-a-time attendance at a conference “need for volunteers” breakfast sparked her activism in our organization, and now the rest is history!

Jyothish Daniel

Jyothish Daniel strongly believes the NODCC is a fabulous organization serving the needs of many families, and he’s right about that! Jyothish became acquainted with the NODCC circa 2003-2004. His daughter, who is now 26, has full Agenesis of the Corpus Callosum, and Jyothish was inspired to join the board because his family has been supporters of NODCC for many years. Gratefully, his professional schedule now allows for it. While Jyothish is just getting started on the board, he looks forward to helping the organization fulfill its goals and mission, especially because it serves the needs of so many. He wishes more people knew how many resources this organization can help people access. He hopes to assist in increasing membership and fundraising which will enable NODCC to do even more good for others in the coming years.

Ilana Davlin

Hi! My name is Ilana, and I’m proud to serve as both an ambassador and a member of the Board of Directors for the NODCC. I was diagnosed in utero with partial Agenesis of the Corpus Callosum back in 1993 — something that was incredibly rare at the time. I always knew I had it, but it wasn’t until I was 24 and did a quick Google search that I truly began to understand what it meant. That moment led me to the NODCC, and my life instantly changed.

For someone born without the full structure that connects the two sides of the brain, I’ve somehow found some of the strongest connections through this community. The relationships I’ve formed are truly some of the best, and I’m so grateful for each of them.

I’m passionate about advocacy, connection, and helping others feel seen — whether through storytelling, humor, or simply being the person who listens when things get hard. Outside of this role, I love live music, making people laugh, and spending time with my chosen family, who are a constant source of encouragement and support. I believe that sharing our experiences helps break down stigmas and builds bridges. I’m honored to be part of a community rooted in heart, compassion, and a deep commitment to understanding one another.

Alexa Smith

My name is Lexy, I am 28 years old with partial ACC. When I was in my mother’s womb, my parents were told that I had partial ACC, and I was told by my parents when I was approximately 4-5 years old. Growing up knowing of my diagnosis helped me be more empathetic to other people. At a young age, I persevered through multiple surgeries for excess CSF in my head (hydrocephalus), epilepsy, Arnold Chiari malformation (surgery twice for that diagnosis), and many therapies to get me to where I am today. Some hobbies of mine are swimming, snowmobiling, and reading romance/fantasy books. I am also a college graduate with my associate’s pursuing a bachelor’s degree in social work. I have experience owning my own home previously. I am an active member of the Community and Adults Committee and look forward to being a part of the Ambassador program through the NODCC as well.
