Chief Barkitect

Educated by the finest at Brown University, Cookie got her degree in Pupular Culture. However, seeking an outlet from her suburban life, she embarked on a journey around the world for enlightenment.

Pawsitively satisfied by her travels, she eventually settled with a job in our humble office.

At the office, Cookie plays gatekeeper. She won’t let anyone come in much further without a jump and a kiss – so be prepared! Her favorite pastimes are playing with her brother Spencer, sunbathing, hunting for acorns (yup, you read that right), and making sure that the floor stays soft.
