In addition to his civil litigation practice, Steve represents physicians and allied health care professionals with the defense of regulatory investigations and actions before the various Boards of Registration, Department of Public Health, and Department of Mental Health.  Steve also volunteers to serve as a guest speaker for risk management programs, including multiple times for the New England Ophthalmologic Society.
