Rob Hillesland Summit-Tribune In the few short weeks following the passing of beloved Forest City auto mechanic Mark Kaiser, customers have increasingly been calling his wife and longtime business partner, Marilyn Kaiser, asking "are you still open?" The answer is yes. Kaiser Auto Repair remains open with Mark having trained Jim Schaumberg, the part-time mechanic who has worked there for several years under Markâs supervision. Both Marilyn and daughter Melissa Nelson said the family is pleased that Schaumberg is staying on and helping to keep the business going. âDad was battling some health issues the last few years, but would supervise and talk him through things,â Melissa said.
