    When he said "call me in six months and let me know" told me he had cut me loose and IO was on my own.

    He’s the best and we’re so lucky to have him in Billings, Mt. Intermountain Health should treat him ver well!

    I’m recovered now from my blood infection. So I thought Dr. Yev would say great, good luck. But he challenged me to investigate the possible cause of my infection further. He scheduled both endoscopy and colonoscopy to determine that no further problems exist in my system. He cared that I STAY recovered. And I’m happy about that. Preventative care, appreciated!
