Never got in to see him. The office was very rude and basically lied to him saying that I was a no show to an appt. they changed without notifying me. Now I am on his ‘do not schedule list’. From what I hear, this is nothing unusual for this practice. Must be nice to be the only game in town.

Went in prior to going for an ordered Independent Med Exam for Work Comp. Before seeing Work Comp ordered me to go he pre judged that I was there only to get disability and dismissed my problems stating hardly anyone is disabled. Only when he saw that I was simply abiding by what I was ordered to do did he discuss my issues and gave me questions to ask the I.M.E. Until that point he wanted nothing to do with me thinking I was trying for easy disability. Unimpressed to the max. Very judgmental

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.
