    Dr Wertheim is fantastic in every way. He really listens and carefully makes a diagnosis, always prescribing the best medication. He is very accessible and ALWAYS responds to phone calls and my chart in a very timely manner. He is very thorough. I have been in his care since 2005 for a chronic sinus problem. He is one of the finest physicians I have ever seen.

    I have tried a lot of medications for both pain and post operatively over the years and have a lot of sensitivities. Dr Wertheim answered my questions and explained his approach (process of elimination) to determine what meds I am and am not allergic to.
