Is private day school an option (non-boarding)? We chose that route for our kids and it's worked out really well - even at a school that doesn't bill itself exclusively for gifted students. We found that there were factors in addition to looking for gifted peers that really made a difference - involved parents, teachers willing to be flexible and teachers who valued what parents had to say, plus an overall higher level of expectation for academics and behavior across the board - from the school, from school staff and from parents. All of these things made it so much easier for us as parents to find a good academic fit for our kids, and our kids also found peers they enjoyed being with and learning with.
Sorry I can't send a personal recommendation - we aren't on the same coast
Best wishes,
