Zimmer joined the office in 2017 as a puppy.  He is a Black & White Tri English Springer Spaniel. 

He enjoys greeting clients as they come in, moving around to 5 different rest spots every 20 minutes, and trips to the bank and the mail box.  By far his favorite thing is when his "humans" come back to the office after school is let out.
