I need a quick response asap..plz

Questions very simple but late. I assigned my recommender as other.

I worked an internship at a hospital and asked the head doctor for a recommendation.
Alot of colleges wont accept other; I didnt know it was a problem. Does my recommend er count as an employer?

Recommender types accepted: Arts Teacher, Clergy, Coach, College Access Counselor, Employer, Family Member, Peer, Other
The following are all the options; if he doesnt count as an employer is there anything else that fits his status?
Please this recommendation is very important for me

You can put Employer for an internship supervisor.

Employer is the most appropriate category.
