I am from out of state visiting in the area. I chose this facility from reading the reviews and roughly knew the area of the location. I made an online appointment. From the moment I walked into the facility, being seen and treated, I have nothing but praise and respect for the staff as well as the care I received. I’m this day and age and just visiting with having an unfortunate reason to be seen/treated I was completely satisfied. A little more pricey than I expected but what can I say? Thank you just the same for your professionalism.

Juan, the medical assistant was good and receptive. The PA who saw me was also good but I just didn't agree with her recommendations. She was gracious to accept my opinion and she maintained her professionalism despite my disagreement. She did tell me that she was putting me on dexamethasone but forgot to explain the dosage; and also antibiotic but I already know what to do with the antibiotic. I thought the prednisone was a little high--40 mg everyday for seven days. It may be a good dose but for me, it gives me quiver and crave for food that's the reason why I was hesitant to take it. She did offer me to be nebulizer but I said I'll do it at home.

Greeted immwdiatly when I walked thru the door and proceeded to the exam room within five minutes. The staff introduced themselves to me as soon as we met walking in the door. Katie, the physicians assistant, awesome PA!! Very knowledgeable, had great “ bedside manner.” Ask more questions about my medical history and then dealled into what she felt we needed to get into today. Truly felt comfortable with everything that happened from the time I walked through the door to the time I walked out the door. Highly highly recommend this office and staff. Thanks for a wonderful visit! Bobbie. Cantu

Wait time was unexpectedly long!  I was there for one hour and 15 mins for an EKG the order was sent the day before so that was not the problem. Was called 15 mins after my scheduled appt and there was only one other person in the waiting room when I was called. Also when I arrived there was one person ahead of me.  Provider was very good and staff friendly. The assistant who who performed the EKG was great knowledge about the procedure. After the procedure I had a wait again another 15 mins.

The online scheduling was easy with the time slot availability shown. The hour is great, open later than others in the area, avoided going to ER. I arrived & check-in was smooth & no wait. Aria looked over my wound & stitch up the cut, & the support staff was friendly & professional. I barely felt it during the process, & she periodically reminded me if too painful, she can numb more. Great facility!

Why did you close the Montclair site? Open only on Wednesday for dermatology? Not good. People need urgent care. Not once a week. Open back up

I was very surprised with my experience here. My appointment was made very quickly. I was seen in a very short period of time. My test results came back in a very timely manner. I was able to speak with a doctor soon after and was taking care of. I was very satisfied with the experience I had here. I definitely recommend using them for any issues you have or any questions you may have.
