Not in the real world, no.
In fantasy novels and films, not in the real world.
No.
The most famous school of wizardry in the world is Hogwarts School of Witchcraft and Wizardry, from the Harry Potter series.
Wizardry's still is a kind of unknown to the ones that think of it as fantasy... If their are real wizards and witches then they must be keeping it a secret and/or giving us hints that their is a fiction or non-fiction way of it...
Not as read in any fictional books. The spells and magic found there are just fantasy. Great fun, but only that, fun. The practice of witchcraft (or wizardry) in the real world can be, but is not always, connected to one or more of the spiritual paths known collectively as Pagan. Studying paganism is the life long work of many practitioners, but most are done as a personal search/study, from books by reputable and knowledgeable authors, or with a mentor/teacher and not in a "school" setting.
In Los Angeles? No. There is an online school of real Witchcraft and Wizardry called the Grey School of Wizardry. It is cheap to enroll in, and provides a TON of material in its courses. It is a seven year program, each year costing around 50 dollars to join. Founded by Oberon Zell-Ravenheart, it is the most genuine school of Wizardry that you can find. Given that magic is fantasy, there are no real schools located anywhere.
