This practice has recently been bought out from what I have heard and boy have they gone down hill…read more As you can see by the picture I included, prior to the following experience, I gave them a 5 star review. I had a virtual appointment on Friday afternoon. They were running 30 minutes behind, which I don't ever mind if a provider gives me the time I need. They did do that. The PA was supposed to call in medication and an order to Fairfax Radiology. Well I call the pharmacy to see if it was ready and they never received the prescription. I then call Fairfax Radiology to set up an appointment and they have no order. Of course all of this on a Friday afternoon before the weekend. I didn't want to page a dr over the weekend even though I didn't feel well, so I sent them a message through their portal system. The lady who responded said they sent them on Friday. That may or may not be true, I don't know, but there was an issue somehow because two independent facilities told me they hadn't received them. I then call to get a f/u scheduled this morning. The receptionist could not figure out how to book an appointment for the provider I had seen. I was on the phone with her for 15 minutes with her trying to figure it out. After 15 minutes of trying she then tells me she has to put me on hold while she can figure it out. After waiting 10 more minutes and her not returning, I finally hung up. It shouldn't be this difficult to schedule an appointment. I then call back to try and talk to someone else and get an appointment scheduled and they ask me to leave a message, that they'll call me back. I haven't heard from them yet. It shouldn't be this hard to get an appointment scheduled and medication/orders sent. Especially when you don't feel well. You can look at my reviews. I generally don't like to give poor ones, and have previously been very happy with this practice. In my experience their providers are very knowledgeable, empathetic, and accurate in their diagnosis. The lady I saw Friday was no exception to that. It is the way the office runs that seems to be the issue. My recent experience with them is the way the office is run has changed and they're difficult to deal with. My hope is they can rectify this because if not, I will be looking for another practice.

Recently, I had a procedure on a Friday and was told I would be called the next day. The checkin nurse had wonderful bedside manners, and comforted me through the IV and process of making me feel comfortable. The Anesthesiologist and Doctor, were as usual, professional. A nurse/representative called me on the following Monday to see how I was and asked a series of questions. When I brought up that I was told I'd be contacted the next day, and didn't hear back, she was polite and explained they don't work weekends. Although I finished the call, it was on my bluetooth, so the call was still connected; as I was waiting for the nurse to hang up, and she went on to have a very rude discussion with her colleague, exaggerating on my responses and questions, mocking me and I found that to be completely unprofessional. It's important to know we are not coming to these appointments because great things are happening to us. You are in an industry where we rely on you to maintain, confidentiality, bedside manner and professional care. Please keep that in mind when hiring and training your staff.
