Dan Ribacoff has worked cases in Brookville for the better part of 36 years. The Garden City office on Franklin Avenue is the base for all Brookville work, and it is close enough that an investigator can be on the ground the same day.
About Brookville
Brookville is an incorporated village in the Town of Oyster Bay, Nassau County, New York. Its population at the most recent census was roughly 3,465. Casework here tends to be personal rather than corporate — family matters, neighbor disputes, tenant and caregiver screening.
The Town of Oyster Bay stretches from the North Shore harbors to the Massapequas. Its casework runs from estate and elder-care matters on the north shore to small-business and family matters in the south.
