Review John Murphy

About Me

John has successfully tried to verdict more than 100 civil jury or bench trials and represents clients before various licensing boards, as well as in mediations and binding arbitrations. While his primary practice area still focuses on defending health care providers and long-term care facilities, he also works with clients involved in business, commercial, and personal injury litigation.

    I often turn to John for his insight on insurance and general litigation issues. I referred a client of my firm to him for an insurance coverage issue and he did excellent work.
