Law Enforcement and ADHD

After much research and many years of frustration, I believe my husband is ADHD.  He has not been officially diagnosed.  However, he has agreed to find counseling.  After he finally agreed to see a psychiatrist, I did a little more research into his specific career (law enforcement) and have discovered an ADHD diagnosis is basically career suicide.  Now what?  What's the best way to go about seeking help without jeoporadizing his career?  It's unrealistic to say, "What's more important--his career or his health" b/c even me, as miserable as I am, know that we need him to keep his job right now.  What are the legal boundaries of a counselor/psychologist/psychiatrist?  Has anyone tried a non-medication route?
