Client Testimonals

We’re proud to hear what clients say about us…

“In reference to Walter at Valentine, we use them. It’s a great system. Excellent customer service. Whenever I have a problem they have someone come out here. He’s good. He’s always there when you need to get in touch with him.”

– Linda, Client

“I’ve been using Valentine almost 10 years now. They put in systems in both of my new buildings. 100% satisfied. Never had any issues with him. He does what he says he’s going to do and he prices it right. I got his cell number so I call him whenever I’ve got a problem. Had a problem at night one time and he got right back to me; we handled it. Good people.”

– Kevin, Client, Long Island

“We’ve known Walter and Valentine Systems a long time. Purchased a couple of systems at my prior company and then purchased a couple here. We purchased one and then expanded it onto another branch. We’ve been very, very happy with Walter. Their response time is good. They’re willing to help and go the extra mile to make things work.”

– Anthony, Client

“We’ve been working with Walter from Valentine since 1988. We used him back then when we expanded our operation and when we expanded this operation we went back to him once again. We’re very happy with his service. In my 35 years of entrepreneurship every business is going to have their challenges. It’s a question of how you handle them and I have to say that whatever it is that arise in this process of these installations, which is pretty complex, that Walter really does a nice job nurturing the process and making sure he’s there as you need him to be whether its remotely or on site. Response time is pretty fascinating. His prices are fair. He knows what he’s talking about. He provides the proper training as you require it. He’s always going to be there for you. Feel comfortable and confident in Walter.”

– Joe, Client

Great Company. We installed cloud based phone service in our office. They were very professional and courteous. The technician Greg was took his time, he explained all of the functions of the new system and was very patient with the staff during the training and also with follow up questions that we had after. Great organization.

Walter and his team performed a well executed upgrade of our phone system - 10 locations spread across the country. Their attention to detail and preparedness translated into nobody being down longer than it took to connect the new phone. Great job, great support.

Valentine Systems replaced our complete office phone system. They were very professional and considerate. They quoted us a fair price and there were no surprises. The gentleman who came to do the installation was very helpful.
