Our Success Stories, In their Words

Client Testimonials

I can not thank John, Teledata, and my amazing IT team (Rick & Maverick) for restructuring all 3 offices with new technologies. The phones have never run so smoothly and the integration of all my services has made our lives so much simpler. I saved money on all my overhead and now I have a team that can fix any issues I have with one text or call. My doctors office is now on high speed internet which helps us care for our patients more efficiently. I love working with John and his team because they are professional, understanding of our needs, and are able to teach my team what’s best for each business. I highly recommend anyone with small businesses to take on this change. Thank you Teledata for making our work day so much easier and more efficient.

-Gabriel Z

I am beyond grateful for the knowledge and help TeleData offered me. I am a small business owner, and the solutions Rick offered were perfect for my needs. They are so helpful and easy to work with. THANK YOU!

-Judi D

TeleData increased my revenue by 20% across the board. A ton of great features and the customer care is second to none! Fully customizable and easy to use. An A++ business

-Melissa Lockamy

On behalf of the Huntington Arts Council, I can highly recommend TeleData Services. We are very happy with our VoIP phones, the switch was worth it but the best part of working with TeleData is easily the service. Everyone I have worked with has been pleasant and patient which is greatly appreciated.

-Sarah McCann

We made the switch from Verizon One Talk a few months ago and the system and programming is way better! Tech support for any changes if I can’t figure it out myself is one phone call and done! Even though Verizon has their firmware on the phones so you can’t use them elsewhere. TeleData found a workaround so we can reuse our Verizon business phones on their platform and even saved us money in the process! Thanks Rick and Scott!

-Rita Kostik

TeleData Services provided us with our new phone system, and we absolutely love it! Setup was easy and Rick is always there when ever we need to make changes to the system or if we have any questions. Thanks guys!

-Jack H Office Manager IBEW LOCAL 508

We have been working with John and his team at Teledata now for several years and most recently on our major renovation work in our Retreat House. Whether it's a small issue of resetting a phone for a new employee or running ethernet cables for new lines, John's team is professional, available (of key importance!) and responsive. I can't say enough good things about the speed and quality of their work and in particular John's follow up to ensure we as the customer are happy and the job complete. They are second to none in service and highly recommended.

-Joey Passionist Missionaries

TeleData Services has a great Voip phone system solution, the support that John Lettieri and his company provides is some of the best support in the industry. You cannot go wrong with TeleData Services brand new door access control system, security surveillance system and firewall that allows you to actually utilize the full bandwidth from the service provider. Having a managed services contract to monitor our network 24/7 365 days a year really puts me at ease. They are by far the best company I have ever worked with and not to mention the ROI they provide will save your company thousands of dollars per year. I highly recommend TeleData Services for all of your communications needs.

-Monique Norwick

John has been awesome from the get-go since we hired his team. We had the new system installed recently and it went without a hitch. Very professional and knowledgeable staff. And they are always very responsive, and extremely helpful. His prices are fair and he is very straightforward and honest. I look forward to continuing working with John and his team for years to come. Highly recommended!

-Nick Amato

We LOVE our new phone system from Teledata Serve. But even more we LOVE the customer service we got every step of the way. The equipment is very intuitive, so easy to learn, and the training got us fully using our phones in no time. It was a pleasure to do business with Teledata. They should get 10 stars!!!

-Caroline Zimmermann

TeleData Services has been top notch in support of our phone system here at our offices in Jamaica, NY. John and his team respond immediately to requests and never fail to resolve issues as soon as possible (usually right away). We are a busy religious order and calls come in constantly, often for much needed donations--without TeleData's services, we would be at a great disadvantage. I highly recommend them to any organization seeking to get the best quality/most responsive telecom services in the NYC/LI area. Kudos to them for dedication to their clients!

-JJ Jamaica NY

TeleData services provided my company with a great Voip phone system solution, the support his company provides is some of the best support we ever experienced. I highly recommend them for anyone’s business who is looking to upgrade their communications and save money at the same time.

-Nicole Nieves

Switching over to TeleData Services has been a good move for us. We are very happy with the service and customer support. We definitely recommend TeleData Services for those looking for a new phone service.

-Michelle Kenton

I was in the dark when it came to phone solutions when I started my new Finance business. As soon as I spoke to Scott Wolf over at TeleData I was put at ease and he explained, in detail, everything I needed to know. John Lettieri followed up with Me and took over the set up process which took less than 24 hours. Would recommend TeleData to anyone and everyone looking for an easy cost effective phone solution. Thanks Guys!

-Mike Mcgrath

At Daylesford Abbey, we have been dealing with John for many years. Just this past year he guided us through a major transition with our phone system. We are very pleased with our new system and John gave us great guidance. He is very professional and networks well with many support services. I highly recommend him and his company because he took the time to listen to our needs and recommend solutions that enhanced our phone system. Over the past years I have always been able to count on John to be there to help us with any issues.

-David Driesch Daylesford Abbey

From a UX perspective, TeleData hosted phone system solution is by far the best system I have interfaces with over the past 10-15 years of being in business. In addition, the voip phone system meets all of my needs and exceeds my expectations. After multiple interactions with other companies I can say you will NOT find a better price any where else.TeleData services has provided the best support all around. I can email, call or text regarding a support issue and within minutes I get a response and my issue is troubleshooted and fixed. I wish every company I bought products or services from were like TeleData services, if I could give a 10 star rating I would Regards Daniel

-Daniel Corado

So TeleData has been providing service and support to the office I manage for months. My role as manager requires I be the point person for our interactions with TeleData. The experience has been AMAZING, John and Dante are extremely competent, helpful and available. I call or email them and within minutes I get a reply. I rated 5 stars but truly they a 10. EXCELLENT EXCELLENT EXCELLENT SERVICE

-Thomas Parsley

As a Facilities Director for a large church in Brooklyn, NY I am always looking for ways to reduce cost and optimize performance. TeleData Services has become an intricate partner in helping me meet those goals. They have positioned themselves as more than a typical vendor, they have partnered with us, not just to sell another product but instruct and train us on the best solutions for our specific needs. I highly recommend TeleData Services for your phone and security needs.

-Martin Robertson Brooklyn, NY

Review TextFor years I had issues with old POTS lines which caused my business phone lines to go down. When it rained the old POTS lines got wet and caused my system to go down. Very frustrating to say the least. I needed a solution and John and I spoke about using a hosted system. Needless to say we are 4 months into the new system I have not had one issue. Even when it rained we have no issues. A hosted system is the way to go. In addition John is always available when I call him. He has made my system reliable once again. Thank you John.
