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 30 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 was having a problem & had a lot of pain. I used my Geisinger & within 10 min I received call letting me know Dr. Harrington was on vacation. She gave me an appt for the next week. Dr. Harrington emailed me on MY Geisinger while he was away on vacation & we discussed my problems & what I should do until I saw him the following week. VERY impressed. Dr. Harrington's staff contacted to let him know about me & as I stated he contacted me via My Geisinger. Dr. Harrington & staff are very thorough! They are always professional and understanding. Very caring.
