Steve was born and raised in Glenview, Illinois. His father, Robert Milliken, did heating and A/C repair for North Shore Refrigeration, and as far back as Steve can remember, he was always very involved in his dad’s work. His dad would take him to work, and Steve loved to run and get parts from the warehouse for the service guys.


In 1970, his Dad opened his own company, and up until high school, Steve worked summers for him as a laborer. Steve was not planning on following in his dad’s footsteps, and while attending Maine North High School, he received a football Scholarship to Northeastern. Unfortunately, he blew his knee out and ended up agreeing to work for his dad for $50 a week in order to learn the business. After 35 years, he is still passionate about what he does!


Steve’s parents started Command Service Center with one customer and built their business by referrals. Integrity was everything and his dad taught him that your word means everything. That’s how he ran the company for over 35 years, and Steve continues to run it with that as his foundation. Now in its 50th year of business, some customers are 3rd generation, which he takes great pride in.


Steve has been married to his sweetheart and partner Mary for nearly 20 years, and is the proud parent of 5 children and 2 grandchildren. They have worked together and taken the business to the next level. They recently opened the newest location for their business in the heart of downtown Antioch. They are active members of the community and are excited about what the future holds.


Steve wanted to add, “Our business is our Family, and our Family is our Business. Meaning, we treat our customers like family. We always want you to be happy with our business ethics, our workers and staff, and value any and all feedback. Our longevity, great customer service, and being a “One Stop Shop” put us aside from all the rest!”
