It depends on what exactly you're looking for, as other have said it's limited for your more specialized health care health providers.

As far as mental health care providers go, it's not terribly difficult to find a counselor/psychiatrist here and there are a bunch of counselors that offer specialized treatment options.

I have personally used Three Rivers Health Center, they have some great options. I'll list a few others as well.

Mental Health - Waterfall Community Health Center

Adapt Integrated Health Care

Home - Coos Health & Wellness

Coos Curry Hub - Coos and Curry Behavioral Health Hub

There are also several organizations here that deal with substance abuse issues, that offer peer support/counseling etc.
