Mazi Tabibipour

Engineer I

I have worked with Cisco UC systems for about 10 years supporting small, medium, and large clients across both private industry and the federal government. My diverse client base has given me extensive experience with troubleshooting and technical support of Cisco Unified Communications Manager, Unity Connection, Instant Messaging & Presence, and other collaboration applications.

NetCraftsmen provides a supportive environment both professionally and personally. You are not just an employee with a number at NetCraftsmen, you’re family.


I enjoy the privilege of having a strong and flexible relationship with the customers I serve and the opportunity to support them in achieving their goals by keeping their Unified Communications systems operating at 100% 24/7.


I am an avid PC gamer and foodie. I also enjoy playing tennis and running. When I am not behind the computer I am out with my wife and friends exploring and enjoying the Northern VA area and its culturally diverse food options and hiking trails.
