Meet Maggie Chamberlain, our beloved office dog who brings joy and warmth to our team every day. Maggie was adopted by the Chamberlain family through the wonderful Barking Back Rescue organization. As a hypoallergenic mini sheepadoodle, Maggie is not only adorable but also a perfect fit for everyone in the office.

You can often find Maggie snoozing in cozy corners or eagerly searching for treats around the office. Her friendly presence and gentle nature make her a favorite among clients and staff alike. When she’s not on duty, Maggie loves spending her free time in spirited chase after chipmunks and squirrels.

Maggie embodies the spirit of our firm – dedicated, charming, and hardworking (while chasing chipmunks and looking for snacks).
