Summer Immersion Geometry Classes for credit

Does anyone have a list of New England schools with day or boarding programs in Geometry for credit? I am looking for an immersion program for credit so that DD can go straight from Algebra II as a Freshman to Pre-Calc as a Sophomore. I know of programs at Loomis Chaffee, NMH and Choate. I am ideally hoping to find a program up near the Seacoast area of New Hampshire or in the northeast Boston area.
