Patient Reviews
May 14, 2017
Doc Hamstra took my wife's case on from a late evening ER visit. Can't say enough positive things about him. Calm, confident, respectful and pure professional. 100% the person you want taking care of your loved ones in that OR. Not that we want to do it again, but if that was the case, Doc Hamstra will be our first call.
