    It really is as good of a primary health practice as you can get without having your own private…read moredoctor. Both of our daughters have been patients here from birth. They have a primary care physician assigned - Dr. Sexter - but they have at some point or another been seen by all of their physicians. Every one of them are great: kind, compassionate, attentive, and responsive. You will feel heard and they will address your concerns. Their knowledge and expertise is extraordinary. The office - staff and doctors - are also super responsive. If you have a pressing question, someone will get back to you that day. If it's an after hours emergency, there is always a doctor on call and they will respond within 30 minutes. The doctors hold daily office hours but it can be tricky to get a hold of them if they're experiencing a volume of calls. An extra perk I like is that they keep appointments available daily for those common but unplanned for illnesses, and they have a separate waiting room for sick vs not sick. It just runs so well you wonder why more doctors' offices don't do the same. Now of course, the one downside is they are out of network. It's not cheap. I think it's worth it if you can, but financially it can hurt if your kids have a lot of illnesses or shots in a limited period of time. They do at least submit the insurance forms for you, and that helps some. I wholeheartedly recommend this practice and all the doctors in it, and have a deep appreciation for how Dr. Sexter and Nurse Jennifer have taken care of our girls.

    So impressed once again with Dr Long after the birth of my second son. This review is so long…read moreoverdue ! She has been my 2 year olds doctor for the past 2 years and we are continually impressed. The office is fantastic , clean , inviting , separate infant space. The front desk staff always try to accommodate you same day and we've never had an issue getting an appointment. Dr Long is caring , warm , and so knowledgeable. She works with us to troubleshoot issues when/if they come up and is readily available. Thank you Spring Valley Peds and Dr Long for the fabulous care of our boys!!! K&M

    Mary Center 3912 Georgia Ave NW Washington DC 20011…read more Quiero expresar mi inconformidad con la forma en que algunas personas del área de llamadas para confirmar citas tratan a los pacientes. En varias ocasiones, las recepcionistas o quienes llaman se han comportado de manera grosera y con muy poco profesionalismo. No permiten que uno hable ni termine de responder si asistirá o no a la cita; interrumpen constantemente, hablan con mal tono y hacen sentir al paciente incómodo o irrespetado. Es importante recordar que muchas personas que acudimos a Mary's Center lo hacemos buscando atención médica y apoyo, no para ser tratadas con falta de cortesía. Un poco de empatía, educación y respeto harían una gran diferencia en la experiencia de los pacientes. Ojalá esta opinión sirva para que mejoren la atención telefónica y el trato hacia los usuarios, porque el profesionalismo y la amabilidad también forman parte del servicio de salud.

    I would not recommend Mary's Center for dental services, specifically due to the inefficiency and…read moredisorganization of their office and scheduling agents. Over a three-week period, from November 13th until today, December 4th (the day of my appointment), I made several attempts--over three separate phone calls--to confirm whether I'd be receiving a cleaning and whether my insurance was accepted. Shockingly, their staff was unable to provide clear answers or even demonstrate a basic understanding of the services their office provides. On the day of my appointment, I had no choice but to cancel due to their continued incompetence. The front desk and administrative team at Mary's Center created unnecessary stress and frustration, failing to perform what should be standard, straightforward tasks in a professional medical office. This experience reflects a clear lack of communication and organizational efficiency. I've since scheduled an appointment with a dentist whose administrative team knows how to do their job without hindering patient care, or delaying it. If you value your time, I strongly suggest looking elsewhere.

I filled out a very,very appreciative and detailed review and 'posted' it (per the 'post' button on the form) but it evidently wasn't received there. Was it supposed to go straight to my Medstar or some other part of the organization? No matter what, my review was as to the quality care I received in every way - concern, attention, care of my injury, and all around wonderful treatment. Other than a computer glitch, which I doiubt since all I had to do was click the 'post' button, I don't know what happened to it.. I have sent reviews whenever I went to Urgent Care. They are the best of the best on every level. I am sorry you didn't receive my post because it was a bit more detailed, but my words recognized what I mention above.

It's been ~6 hours since the visit, no call, no results. Logged into their site - no after visit summary, no treatment recommendation. The clinic has no pager, no voicemail to get a follow up from the doctor or staff after hours and only a typical message to call 911 in emergecy. Result: no diagnosis, no prescription, no visit summary, like she hasn't been there.
