I have purchased parts, received guidance and advice which has saved me lots of time, aggravation AND money from Joel who is the former HiLo Plant Manager.

I (Joel) am the former Plant Manager of the HiLo Company and have been around HiLo for the past 30 years. That's because my father-in-law is Jim Snyder former owner of the company. It was his brother Don Snyder who started HiLo back in 1955.
Joel can be difficult to connect with because he's REALLY busy but he's extremely conscientious and will definitely get back to you. I have found that if I send an email and ask him to call me that works best. I've also had good luck if I try to call early in the morning. Remember, it is a low overhead operation so they don't have administrative help.
