Kelly Radunske

Owner/Media Relations/Marketing

Kelly earned a bachelor degree in 2004 from Michigan State University with an early focus in Special Education and later graduating with a degree in Business Management.  


While living overseas with her husband, Brock, Kelly gained the certification to teach English as a Second Language (ESL) and taught English in South Korea to kindergarten-middle school for several years.  Kelly also gave birth to their first child while living overseas and observed her own young daughter grow up in a country with strong language barriers and their own set of unique cultural norms. She quickly learned how important community support is in learning and development, and tried to never take for granted the supports that were given to assist her daughter through this time. 


Kelly now resides in Plymouth with her husband, son, and daughter. She is excited to personally help families within the community in any way possible!


Brock Radunske

Owner, CFO

Brock grew up in New Hamburg, Ontario and went on to play hockey at Michigan State University where he earned his Bachelor Degree in Organizational Communications.  From there he met his wife Kelly and they began following his hockey career internationally, living in Switzerland, Germany and South Korea.  


Throughout many years of hard work, success and dedication Brock earned his South Korean citizenship and was recognized as the first ever North American to represent Korea’s National Team.  

He went on to participate in the very recent 2018 Pyeongchang Winter Olympic Games for South Korea Men’s Hockey.  


Brock grew up watching his older sister overcome challenges from her own struggles with mental health. He has also learned the true meaning of ‘hope’ and ‘perseverance’ after witnessing his own mother recover from a severe traumatic brain injury. Throughout these times, Brock was given tremendous amounts of support from his team and the communities in which he resided. After 15 years of professional hockey, Brock and his family have settled back into Plymouth, Michigan and are ready to give back to the community and help support other families as they start their own journey of healing.
