I am privileged to have Dr. Witteles as my physician. He combines expertise with kindness and compassion.
Great doctor!!!
The Fellow who first spoke with me was engaging and seemed to have time to hear my concerns. The physician I was scheduled to see was quite obviously in a hurry, gave me a cursory evaluation, stood and never sat, changed one medication and sent me on my way. I completed a multi-part form on which I listed numerous symptoms and conditions, none of which were addressed or even acknowledged. I drove a combined 7 hours, waited for another and was briskly dismissed in a matter of just a few minutes. I complained of shortness of breath and pulmonary edema and was hospitalized for two days, AFTER Dr. Witteles assessed me and sent me away. I will never see that doctor again and am reluctant to divulge such information to another physician in this manner again.
