"I had a problem with my National Optronics 7E edger. We worked with the company technicians replacing some parts however we were not able to resolve the issue. I then found out about Mark Henderson and MH Optical Services. Over the phone he diagnosed a problem with the 7E card cage. I bought a rebuilt 7E card cage from MH Optical Services for much less than a new one. When it arrived, Mark patiently helped us get everything adjusted properly and back in good working order. It was a pleasure to work with a dedicated and knowledgeable professional like Mark."

"Mark's attention to detail is like nothing I have ever seen. He tears down every National Optronics machine and then rebuilds it from scratch.  After seeing what he did for my National Optronics 6ES edger rebuild, and how little he charged for it, I can only conclude that Mark and his team possess a special form of insanity that they actually love this extremely detail-oriented work.  I would highly recommend MH Optical Services to anyone who has high expectations that typical service departments have trouble meeting when refurbishing Optronics machines.  He knows these National Optronics machines inside and out.  "

"My first contact with Mark Henderson and MH Optical Services was in May 2013 when we were restoring a mobile vision lab owned previously by the Remote Area Medical Corp. Even though he didn’t know me from Adam he spent close to an hour helping a technician trouble shoot a problem with a National Optronic Horizon 3 edger. He refurbished two Horizon 3’s and they worked like new. In 2016 our group decided to upgrade our edgers. We found 3 Optronics 7E’s which needed to be refurbished. Mark refurbished/rebuilt all three which saved us approximately $25,000 over the cost of purchasing one already refurbished. All 3 work like new. He has also refurbished 2 Optronics 4T Tracers for us. Over the last five years I have called Mark many times to solve problems with our National Optronics equipment. He is always ready to help and takes as much time that is needed to solve whatever problem that I have. I highly recommend Mark."

"Mark and his team at MH Optical Services provides nothing but the best for his customers who need help with their National Optronics Equipment! We have bought multiple Optronics machines (Horizon 3 Edgers, 4T Tracers) and as well sent them our Optronics machines to be rebuilt. He goes above and beyond to get the job done. I would recommend them to anybody for their Optronics equipment needs!"

"I have used the services of MH Optical Services LLC for several National Optronics machine rebuilding needs such as the Optronics Horizon 3 Edger and 4T Tracer. His work is great! The machines look and run like new when he is finished. His attention to detail and quality of work are refreshing in today’s world. You can count on the job being done right the first time. As far as I’m concerned this is the only place I will take my Optronics equipment."

"Being in the Optical Retail/Wholesale business for over 30 years, I rely on my Optronics equipment for accurate and fast service. Before finding Mark Henderson of MH Optical Services it was always a struggle to find fast dependable service people for my Optronics machines! Now with Mark I feel I have another employee to rely on for Tech-Service and friendship!! When any problem arises with any of my Optronics 2G, Horizon 3, 7E and 4T equipment the first thing we do is “Call Mark”!!"
