There is no publicly available rating for this care provider for one or more of the following reasons:
  1. He or she does not see patients in the outpatient clinic setting.
  2. He or she sees patients, but has not yet received the minimum number of Patient Satisfaction Reviews. To be eligible for display, we require a minimum of 40 surveys. This ensures that the rating is accurate and statistically reliable.
  3. He or she is a community provider, not a Geisinger-employed provider. Community providers tend to see patients in their own private outpatient practices, which we do not survey.

I liked the metaphor used to describe difference between a CAT scan & PET scan used by *Dr. V_____ _____ talked to me in laymen terms!!

When Dr. Vadakara saw a spot on lung from the CAT scan, he wanted me to go to a lung specialist. I didn't want to go. He recommended I go. If it wasn't for him, I wouldn't have known of my sarcoidosis.

Doctor concerns about situation and went above & beyond to assist with my condition with whatever medications and procedures that were available to consider.

The doctor asked me why I had bags under my eyes and why I was wearing pressure hose, but he made no recommendations. He asked "Do you want a CT scan?" I am 87 years old and I have no problem with my mortality.
