Does the following commas need to be where they are? Thanks for your help!

I was recently informed by my professor,(teacher's name here), about a job opportunity in your Head Start or Michigan School Readiness programs, that might be available in your school district.

The first two commas are fine; the third one is not needed.

The sentence is awkward, though -- repetition of the "in" prepositional phrases:

in your Head Start or Michigan School Readiness programs
and
in your school district

One of them needs to go; perhaps they can be combined in some smooth way.
