Tim Grunditz Executive Director

Tim Grunditz has had an interesting journey on his way to HCC. He grew up a pastor's son but wandered from the Lord after tragedy struck his life. When he returned, it was like the prodigal son’s homecoming. Deep in hTim's heart, God began to stir a passion for bringing the gospel to all nations.  Meanwhile vocationally he started his independent contracting company. After 16 years of running his company, the Lord converged Tim’s passion for the gospel with his experience in business and birthed his role as the executive director of HCC in May, 2014.  He is joined in serving the Lord by his wife Kathy and young daughters Lucy, Jill, and Ruby.

Josh Driver

Josh Driver Program Coordinator

Josh Driver's first contact with China was a trip in 2007 after a friend casually invited him to visit. During the trip, he instantly fell in love with the people, language, culture, and food! Subsequently, Josh transferred universities, locations, and degrees in order to pursue God's call to love and share life with the Chinese. This call led him to serve the Chinese as a student, teacher, businessman, and as the program coordinator of HCC in July 2014. Josh is proficient in Chinese, enthusiastic about life in Minnesota, and looking forward to meeting you. Contact Josh at

Kim Sollie Coordinator of Volunteer Engagement

Kim sensed a call on her life to full-time Christian ministry during her college years and has loved the assignments the Lord has given her.  She had the privilege of serving as a missionary for 20 years in Ecuador, South America.  Kim served as the mission and outreach director at a Twin Cities church for the past 13 years, during which the members began to reach out to Chinese both locally and abroad.  Through this exposure, a love for the Chinese people and culture developed in her heart. Kim lives in Maple Grove with her pastor husband, and they have four adult children. She enjoys the outdoors, cooking, reading, and hanging out with her grandchildren.  Contact Kim at

Amy Wang Program Coordinator

Amy's first friendships with international students began when she was an undergraduate at Winona State. What started as a desire to better connect herself to Chinese students in Bible study morphed into intentional language acquisition and enrollment in Chinese courses. Amy fell in love with China's language and culture, and, later, fell in love with a man from China, her husband Theodore. Amy joins us fresh from Hebei, Shijiazhuang, China, where she lived as an expat teaching English. Contact Amy at
