Mirman School in Los Angeles has a good reputation. We have friends who are happy there. Los Angeles generally has lousy schools but has better than average gifted services. It also offers a very small highly gifted option K-12 but the only way to qualify is through their own clumsy testing. North Hollywood High School hosts it. There is also a small special honors program at Walter Reed MIddle School/ IHP where they except a wide range of data points as well as offer their own test. All public schools are free of course but most families donate $1-2k.
