Chrissy makes art jewelry and has been teaching metalsmithing at the ArtsCenter in Carrboro for 8 years. She is a member of the Chatham Artists Guild and participates in the Chatham Studio Tour.

Her growing awareness of the expanding tick and tick-borne disease problem in North Carolina has stimulated her interest in helping to educate our community on the dangers and ways to increase safety.  Chrissy joined the TIC-NC board in 2015.

McGregor Bell
McGregor Bell lives in Durham with his wife and son.  He grew up in Raleigh and went to school at UNC-Chapel Hill.  Until recently, Mr. Bell enjoyed walking through woods and wading through swamps until the growing populations of ticks and associated human pathogens caused him to see things differently.  In addition, the number of people he knows who have been affected by tick-borne disease has increased his interest and concern.  McGregor is pleased that being part of the TIC-NC Board allows him to increase his involvement in spreading knowledge about the importance of prevention and prompt treatment of tick-borne infections.  He is an accountant for a local university and enjoys photography. McGregor joined the TIC-NC board in 2016.
