A recent example of great customer service I have experienced includes:
Denver Metro Chamber of Commerce
www.denverchamber.org account rep, Kate Jackson goes above and beyond for me. She helped me find the right programs for me at the beginning and keeps sending appropriate leads and speaking opportunities in and out of the Chamber. I have had questions a few times and she always responds right away. Her proactive approach is great - contact Kate if you are considering the Denver Metro Chamber.
