    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

    While I was pregnant with my first daughter, we were referred to Dr. Nguyen by a close friend. We…read moreabsolutely loved Dr. Nguyen and his team. He took great care of my daughter in her first two years of life. She always finds something entertaining in the waiting area, whether it was the TV or the giant fish tank. By the time our second daughter was born, we had moved to a new neighborhood so we switched to a practice that was closer to home. Otherwise, it was a 20-minute drive to Seven Corners. If you live in or near Seven Corners, I highly recommend Dr. Nguyen!

    Now that I have 2 little boys (2 years old and 4 years old), I've had the opportunity to bring my 2…read moreboys to Dr. Lamson to get their COVID19 Vaccines (as our local pediatrics were completely out of vaccines). My 2 year old is highly afraid of Shots AND doctors, but Dr. Lamson was able to entertain the little guy enough where he allowed him to pull his pant leg up so that he could administer the vaccine on his thigh, he cried a bit, but after that, he wanted Dr. Lamson to play with him. My 4 year old, on the other hand, loved how Dr. Lamson installed a video game system in the waiting lobby and he also enjoyed the decorations that were put up in the patient room. He asked me if he could come here for his future wellness visits and we just might schedule both of their wellness visits here and just leave emergency and sick visits for our local pediatrics!

    Was previously with One Medical in Tysons; moved to this location earlier this year as the prior…read moredoctor moved to another practice. My experience with OneMedical Rosslyn has been wonderful. The physical site is gorgeous, parking is nearby (not free though) and it's metro accessible. It's clean, the staff are friendly and professional and they have an in-house lab which saves a trip to Lab Corp. Additionally, they now offer mental health services which is a nice bonus. If you need a prescription called in to your local pharmacy, you can request via their app or website. If you have a non-urgent issue and need advice, you can message a nurse or doctor for help. If you have an urgent (non-emergency) issue, you can usually get an appointment relatively quickly; scheduling through the app is very easy. The user interface is easy to navigate. Also, the staff don't try to "upsell" you in any way or pressure you to get an unnecessary vaccine or test. In closing, I highly recommend OneMedical. It's worth the annual fee (which isn't that pricey IMHO). There are locations throughout the country - and the network of providers at every location is superb.

    I missed One Medical so much when in Florida. Whether it's the mobile app where you can basically…read moredo anything you need medically, the friendly desk staff, or the great NPs and medical team, they will take care of you. I recommend!
