Is it grammatically wrong to use "from which" or just "where" instead of "from where" in this sentence? To me, it feels unnatural to see "from" and "where" are used together.

You are correct here! "From where" can actually be substituted with "from which" AND "where" here without changing the meaning of the sentence. Ex: Her headquarters, from which the teaching's organized, are in Seoul's business district. Ex: Her headquarters, where the teaching's organized, are in Seoul's business district.
