PWSA-WI Junior Advisory Board Members

Kameron Boser

My name is Kameron Boser and I have an older brother, Kyle, who has Prader-Willi Syndrome. I attended my first PWSA-WI, Inc. event when I was three months old and my parents brought me to Hobby Day. As I got older, I realized I wanted to take on a more active role so I started volunteering at various events and began fundraising for the walk-a-thon, raising over $1000 for several years in a row. When I am not volunteering for PWSA-WI, Inc. I am involved in the Nicolet High School FEAR (Future Engineers of American Robotics) team. I also enjoy hunting with my dad and spending time with my friends. It is an honor to be one of the original members of the PWSA of WI Junior Advisory Board.

Makenzie Gaulke

My name is Makenzie Gaulke. I was appointed to the Junior Advisory Board because I want to help support PWSA-WI, and also because my brother Greysen Gaulke has PWS. In my free time I enjoy playing sports. I play basketball, volleyball, and lacrosse. I also like studying biology, physics, chemistry, math, languages, etc.  This is my second time volunteering of YAP.  I’m so happy that I can support PWSA-WI and be on the PWSA of WI Junior Advisory Board.

Eva Glass

Hi, I am Eva Glass, niece to Jamie Milaeger, and lucky sister of Josaphine Glass, both with who I get to share the wonderful world of Prader-Willi. My aunt introduced my sister and I to this amazing group who became my second family. Having a special needs sister of my own drives me to want to help make a difference with these amazing people. I feel blessed to have been asked to join the PWSA of WI Junior Advisory Board where I can put words into action. I am a freshman at Lake Country Lutheran High School where I enjoy my time not only in my classes but on the volleyball court or ski hill with my teams. I look forward to continuing to make changes in the world as I follow my dreams to become a NICU Nurse.

Josaphine Glass

Hi, my name is Josaphine Glass. My aunt Jamie Milaeger is on the PWSA-WI Board. I was introduced to PWSA-WI by volunteering to help my aunt with the Wisconsin Snowflake Ball. I enjoyed it so much I continued to volunteer, and I am now part of the PWSA of WI Junior Advisory Board. In my free time I like to go rock climbing at Adventure Rock and take pictures. I went to Florida for the National Conference to volunteer with the YAP program in 2017 and am excited to be coming back in 2019. Since being on the Jr Advisory Board I have realized how to love and respect everyone no matter who they are or where they come from. This is important to me as I have a sister with special needs.  The best part of being on the board are just being with people with PWS and having fun. Most of all meeting new people making a difference in their lives no matter how big or small makes me truly happy. I want to keep being a part of this amazing board for as long as I can.

Hi, my name is Maddie Tula. My mom, Kim, works for PWSA USA, is on the PWSA-WI Board, and coordinates the YAP program for the National Convention.

I have been helping with the YAP program at the National Convention since I was 8 years old. In my free time I enjoy riding my horse, snowboarding, and hanging out with my friends. It is a great eye opener to life when you are with these amazing individuals. I am so thankful my mom has brought me into this community.
