    We have been to many allergists and doctors who have not been able to get to workable solutions. Within 2 visits my daughter is now on a medication that is exceptionally improving her quality of life. Dr wertheim truly cares about patients well being and is committed to helping find solutions.

    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.

    Very thoughtful about your symptoms. Went out of his way to squeeze me in when I was having the allergic reaction. Set me up for future testing. Wonderful communicator, made sure you understood what he was explaining.
