Welcome
Apis Law is a law firm in Goffstown, New Hampshire with a focus in personal injury, employment, real estate litigation. The firm is named after the honey bee: apis mellifera.
I have been keeping bees for several years. It is challenging, humbling, and rewarding - just like the practice of law - where predictability can be elusive and assumptions often corrected by the discovery of new facts, circumstances, and different points of view.
Like bees, a good litigator is unassuming, humble, industrious, and, when appropriate, will let an adversary know their proper place.
For these reasons, I chose the name Apis Law.
