Would leave zero stars if it were an option. My husbands cancer care is teated there in Lalispell so we thought dr Diegel would be best, also since his mom has seen him. We missed a referral in 2013 it's now 2017 and he won't take him. I have NEVER been denied by a provider. Apparently he is too busy and must think highly of himself. We cannot see the Dr that would be able tell the providers at KRMC details and knows his family history. Don't miss an appointment this guy thinks he's perfect.

Doesn't return calls, if it isn't an easy diagnosis he says he doesn't have time to help you

My wife and I both have auto-immune and both are patients of Dr Diegel. He is well respected in the medical community and he is an amazing doctor. He has been a tremendous help in both diagnosing and ongoing treatment of both of our auto-immune disorders. I feel like he literally gave my wife back to me after her lupus had robbed her of her life, so when i had bizarre symptoms and they said I needed to see a rumatoligist there was no hesitation. He is a doctor who really listens and heals!

He listens and offers exercises and other techniques before prescribing meds. He remembers you and asks questions about your life and health, he is a very competent physician.
