Reid Rowlands  For 35 years Reid has been a commercial developer in downtown Newark.  An avid woodworker and mountain biker with a passion for Passive Construction.

John Nuss is a retired Union Carpenter who now heads up our shipping department.  John loves working trade shows as anyone who has tried to walk by our booth without stopping in will testify.

Ryan started interning summer of '14.  His duties include (but are not limited to!) stock boy, pre-making shipping boxes, maintaining the shipping department, recycling carboard boxes, and taking Chloe for walks.  Here he is volunteering for a City of Newark Downtown project.

Chloe is the shop bench dog.  She loves going outdoors, running, sleeping and begging for treats from customers.  She especially enjoys when the UPS and USPS trucks pull in - she knows she is assured a treat from our regular drivers!
