problem solved

Josh is a big help and an asset to the business. When I called him recently with a list of questions, he showed just as much patience with me toward the end of the call as he displayed at the start.
It's a breath of fresh air to be able to feel like you're not being a bother to someone because they have patience, confidence, and a way of putting things that naturally gets a person straight on matters that seem complicated to them.
Josh makes people feel comfortable and not like they need to hurry up and get off the phone.
THANKS TO JOSH FOR BEING A GREAT BUSINESS MAN AND AN UNDERSTANDING HELPER!

confidence builder

When I first bought my gb4000 and MOPA units, I was more than a little intimidated.
I called and spoke to a gentleman named, Josh, and he cleared my quandaries right up!
Josh is an asset to the company and the business field. He gave me a comfortable feeling on the phone and had plenty of patience for my many questions.
I really appreciate the top notch

MOPA Gb4000

I decided to purchase a mopa and gb4000. I found several dealers although one dealer (Joshua Parker ) seemed to stand out among the others. My first call to him probably lasted 15 minutes. He was very helpful in explaining the system and it was clear to me that he would be very helpful after the sale. Health Harmonic is a good dealer for this system.

Amazing Support, very trustworthy

Joshua Parker is an amazing person and incredibly helpful. I have known him for the last 17-18 years and I have bought many devices from his company for my clinic in Dubai. You can rely on his knowledge and experience. Thank you Josh for your help and constant support.

Quick Response and caring service

Josh was terrific helping me troubleshoot a problem with my GB-4000. The device was not faulty, I accidentally changed the mode to Audio mode which does not illuminate the RF Indicator light. With his advice, I was able to easily fix the problem. I could also tell that he really cares about helping people! Josh you are the best!
