The McCullough representative who serviced my equipment was thorough, knowledgeable and personable. This is just like all McCullough people I have met through several years. I wish the appointment window could be morning or half day. It’s from 8:00-5:00. That’s long, don’t you think?

Thomas was knowledgeable and saved me from spending a bunch of money on something that would not have helped me at all. Much better technician than the last one. Thanks Thomas!
