I am so happy to have discovered ConvenientMD Urgent Care in Portland, ME. I was able to see a PA almost immediately, had x-rays, spoke with the PA once again and was on my way. The office is clean, well lit and welcoming, as were all of the staff people with whom I had interactions.I will absolutely use this urgent care facility again should the need arise.

By far the best urgent care clinic experience I’ve ever had. No waiting involved, the whole process took a total of 15 minutes. They were able to fill the necessary prescription in house, which was especially convenient on a late Sunday evening. The staff was exceptionally friendly as well.

I walked in to ConvenientMD Urgent Care to get a flu shot for school around lunch time. I was in and out in about 20 minutes! I was expecting to be there much longer since they don't do appointments. I was very pleased with the quick service and professional service from everyone involved. I would highly recommend going here for your next flu shot!

I was so impressed with ConvenientMD Urgent Care. I had an outbreak of poison ivy on my ankles and backs of my legs and ConvenientMD took care of me with no appointment. I was in and out quickly with a prescription in hand. I am so glad they are in Portland! Thank you! There was a lot of open and available parking and it is in a great location close to the highway and grocery stores. I can't say enough about this place!

First visit to this Urgent Care and it was amazing. I was in and out in less than an hour which included a minor procedure. Staff was friendly, professional and very attentive. The location was beautiful and clean. I will definitely use this site again in the future!
