A niche service provider if ever there was one, Dan Notoi has a reputation in Skokie for knowing his way around an endoscope. There aren't many independent individuals who develop an expertise with this medical tool made for going places one would rather not think about. However, either on-site or in his home-based workshop, Notoi can fix an endoscope, and fast. Providing reliable customer service as well as technical know-how is a hallmark of his. Regardless of whether or not you need his skills right now, like everyone, eventually you'll get it in the end.
