DO NETWORKING EVENTS REALLY WORK?

As an independent consultant I understand the importance of making connections and expanding your network.  Even so, I still find myself experiencing the networking burnout where all I want to do is walk around with a stack of business cards and a sign with my bio around my neck.

Networking events are the perfect gateway for practically anything you want to accomplish for your business. These events are designed to help professionals in your area get together to meet and exchange valuable information and opportunities. Even if all you do is introduce yourself and your company to other attendees, you’ll at least circulate some positive PR for your brand.
