Variety of work and technologies, opportunities to learn, and smart co-workers who work hard for the customer. We all love doing networking!


I enjoy discussing technology and best practices with staff and customers and having a positive impact on networks. And constant variety and learning.


I do a lot of reading, especially science fiction, and also walking / hiking. There’s also home and yard maintenance, but “like” doesn’t always exactly apply to those.
