The 63-year-old Baldwin Republican has lived in Douglas County the past 32 years.
"It has been a great experience," he said. "And I want to do what I can to guarantee that Douglas County will offer the same kind of opportunities and quality of life for the next generation that we have been able to enjoy."
Johnson is a former member of the Lawrence Chamber of Commerce board of directors and past chairman of the Community Task Force on Elementary and Secondary Education for the Lawrence school district.
He serves on the governing board of Bert Nash Community Mental Health Center. He is a board member of Boys and Girls Club of Lawrence and Douglas County Bank. Johnson is a retired CEO of Charlton Manley Inc.
He said good planning is key to dealing with growth issues.
"It's good news that the county is growing," he said. "I support smart growth, and I'm a firm believer in planning."
He said he is running because he cares about Douglas County.
"Douglas County has got to be one of the best places in the United States to live," he said. "It's a great place."
He and his wife, Pauline, have eight grown children; Bob, Tom, David, Mary, Beth, Paul, Patrick and Julie.
The 37-year-old Vinland Republican has owned Chubby's Welding and Machine for 16 years. He said he has met many people, especially farmers, through his work. He said rural residents need better representation on the commission.
"The reason I got into government is so people like myself do have a voice," he said.
Mock said he is interested in protecting home-based businesses and agrees with the planning commission's proposal for a three-tiered system.
"We need to have our own system. We're not like other counties," he said. "We need to do what works for us."
Mock said he would champion home-based businesses as a commissioner.
"I think the county has an obligation to keep people like myself with less than four employees on the path to steady growth," he said. "I support the businesses as long as they're not a nuisance to the surrounding area."
Mock graduated from Lawrence High School and is a lifelong resident of Lawrence. Prior to starting his company, he was employed at Lawrence Paper Co., from 1980 to 1984.
He coached little league baseball for six years and is involved in his son's motorcycle racing.
Mock and his wife, Teresa, have four children: Bryce, 6, Brandon, 4, and stepchildren, Jennifer Miller, 17, and Kevin Miller, 14.
