@blg529. Will UCLA provide you with the same type of introductions/exposure to the companies/career that you want to work at/in that Stanford/Kellogg would also provide? This would depend on your desired career path. Of course the name brand is good to have, but if UCLA has connections to large fortune500 that are looking for brand managers (seems like thats what you're looking for), then it might be worth it to stay in LA.
Also, you'd have to weigh your husband's career and your relationship's long-term goals. If he's making heavy money already, its definitely not worth it to uproot/sell house. Of if you plan on having a family, do you want to stay local to LA? if so, do you not mind moving away for school and trying your luck after MBA to move back to LA?
im sure you've already thought about these things tho. hopefully i'm not convoluting things more.
