Customer Support

"For over 20 years, support from the Concurrent team has been superb. The sales account manager has always been very responsive to our needs regarding purchase order requests, licenses and any other issues with our Concurrent systems. The field analyst, who provides technical support is excellent. He always responds promptly and demonstrates extensive knowledge of the systems. I appreciate his ability to explain things in a clear, precise way. They are a great team." Kathy Ballester, Lockheed Martin, Owego, NY
