“It is always a pleasure to work with ZT Technology Solutions. As a Technical Project Manager, I highly value professionalism, customer-facing skills, prompt delivery of services, and technical knowledge. ZT brings all this to the table and more. John Yassemedis is excellent technically, and both Mike Dazio and John Tsimaras have a thorough understanding of the needs of the business, both for our company and our customers. I have no problem putting them in front of the customer, and appreciate their attention to detail, and the completeness of their solutions.”

“We here at Frontier have a venue to give recognition to our employees that we work together on different projects, it’s called ‘RAVE’ (something to rave about). But I have always in the past acknowledged the vendors that go far and beyond the usual assistance that is needed to restore problems. That being said, I would just like you and your team to know Frontier also has to RAVE about the type of support you guys have been to us. In the past 2 years I’ve been working and coordinating different issues and projects with the ZT engineers & they have always provided excellent work with a GREAT attitude. The other GREAT thing is that I know you guys are always a phone call away if needed. Your team has always got back to us in a most expeditiously time frame. Your Team has always demonstrated a HIGH degree of professionalism. So THANKS for being there when we need you.”
Lavance Mac McLendon, Frontier Communications, TIER-II Voicemail Support

“John and his team of highly qualified Engineers at ZT have been a reliable and responsive vendor for the Boston Globe. At first we may have been a bit skeptical engaging the services of new and unknown vendor, but we have found from the beginning they worked closely with our IT staff and have exceeded the service and disaster recovery levels with a personal touch. We highly recommend John and his team at ZT.”

My team has used the ZT Technology Solutions Tier 3 DMS technical support services of for several years now,supporting our embedded base of Nortel legacy DMS-500. 
We were looking for a high quality and cost effective solution for long term support and found ZT to be an excellent alternative to the existing OEM. ZT’s technical support people are highly experienced, knowledgeable and very responsive. ZT has allowed us to continue to maintain our legacy equipment while we migrate to our next generation switching platform.
We have been very pleased with ZT Technology Solutions and highly recommend their services.

I would like to write a short note to express my sincere thanks to ZT Technology Solutions for the continuing professionalism they have provided to FLIR with a multitude of ongoing UAS projects over the last few years.
We have worked exclusively with their FAA certified PIC John Yassemedis during these special projects for piloting missions with a multitude of both multirotor and fixed wing platforms. John brings over 30 years of experience flying and it shows.
The professionalism and skill level of piloting skills ZT delivers is outstanding as well as hours of consulting during the project. We currently employee licensed UAS pilots but none have the level of expertise that we needed for this project. Without hesitation I personally have recommended ZT to several of FLIR partners for their UAS needs, and they were also extremely satisfied with my recommendation. If you’re considering ZT Technologies Solutions for your next UAS project, you won’t be disappointed.
Nick Lagadinos Engineering Director at FLIR Systems
