I was going to mention San Francisco Conservatory, but the guitarist I know who thrived there was classical. The jazz program may have guitar, but I can’ t find it on the site of the Roots, jazz and American Music program https://sfcm.edu/curriculum-rjam-undergraduates
Other BM programs- you would have to look into details:
University of Puget Sound School of Music has classical
guitar https://www.pugetsound.edu/academics/departments-and-programs/undergraduate/music/at-a-glance/degree-nondegree-programs/
University of the Pacific Conservatory is a possibility https://www.pacific.edu/academics/schools-and-colleges/conservatory-of-music/academics/degrees-offered.html
These two are not BM program:
Look at Lewis and Clark https://college.lclark.edu/departments/music/
Pomona https://www.pomona.edu/academics/departments/music
I suggest you contact these schools and ask. Often times a liberal arts type college will find you a teacher, and the BM programs may have jazz guitar, it’s just hard to find on the site. The classical guitarist I know also plays jazz professionally.
