    We've been bringing our two daughters to this pediatrician's office since they were born, and after…read moremore than ten years, I can confidently say we couldn't have asked for a better medical home for our children. What sets this practice apart is the truly personalized care. The doctors and staff don't just know our girls' medical histories--they know our girls. They remember details about their interests, their personalities, and their quirks. Walking in for an appointment feels less like visiting a medical office and more like seeing caring extended family members who happen to be medical professionals. The trust our daughters have in their doctors and the entire staff is something I never take for granted. They actually look forward to their check-ups, and even when they're not feeling well, they feel safe and comfortable here. That level of comfort is invaluable, especially when dealing with anxious moments or difficult conversations about health. The doctors also take care of us as parents. They helped us understand how to read our kids' symptoms--what is serious and what is normal. As nervous, first-time parents, that type of support helped us calm our own nerves on countless occasions. From routine well-visits to sick appointments and everything in between, this office has consistently provided exactly what we need: expertise, compassion, accessibility, and genuine care. After a decade of experience here, I recommend this practice without hesitation to any parent looking for a pediatrician who will truly partner with them in their children's health and wellbeing.​​​​​​​​​​​​​​​​

    If there were a draft pick for pediatricians, Dr. Bennett would be our #1 overall. He met with us…read morebefore our daughter was even born, showed up at the hospital like a pediatric superhero when we had no idea what to do, and has been part of our lives ever since. His bedside manner is honestly unbelievable--he somehow manages to calm babies, reassure parents, and crack a joke all at the same time. Our daughter trusts him, we trust him, and we're convinced he could probably negotiate world peace if toddlers were involved. The entire practice runs with the perfect mix of professionalism, warmth, and genuine care. They've become truly indispensable to our family, and we couldn't imagine navigating parenthood without them. Five stars, ten stars, all the stars--Dr. Bennett and the team deserve them all. And if you get a chance, pick up his one of his books. My favorite is The Fantastic Body.

    I've had a very frustrating experience with Growth and Wellness Pediatrics, LLC. Scheduling with…read moreour actual pediatrician is extremely difficult--she is always booked out, and we often end up seeing a random provider instead. Unfortunately, those visits have felt rushed and lacking basic bedside manner, which is not what you want when it comes to your child's care. On top of that, I submitted required school health forms and was later charged a $20 fee without ever being informed ahead of time. The documentation they provided actually lists the fee as $15, yet they still charged the higher "updated" amount without any notice or consent. I had multiple interactions with the office (calls, in-person, and email), and at no point did their medical assistant, Casey, or anyone else mention a cost or price increase. Patients should not be expected to pay fees that were never disclosed or agreed to. This experience wasn't about the money--it's about transparency, communication, and quality of care. Unfortunately, this practice fell short on all three. I hope they take steps to improve both their patient communication and overall experience.

    I love this office. It's kids friendly. My kids have seen Dr warner for 15 years. (Before she was…read moreat this location) Both Dr Warner and Dr Levitt take the time to listen to your concerns. They're very fun and outgoing with the kids. I love that my kids don't fear their doctor they have very engaging conversation. The office is located in their own shopping center so it's a plus if you need to do some shopping. Plenty of parking.

    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

    In most aspects it is your standard OneMedical office. The providers are nice and punctual, it is…read morereasonably accessible by metro, sits across from county public parking, and even has appointments on Saturdays. It's also one of the OneMedical offices with a pediatric practice. So why only 3 stars? The lab, especially on weekends, is a calamity. One time my wife had to wait *an hour* to do a simple lab test. Another time it was an unnecessary wait and hassle just to pick something up from the lab. Honestly, if you anticipate needing lab work on a weekend, you may want to consider another location unless you're out of choices. I'm not sure what's going on as neither of us has ever waited more than a few minutes for the lab at any other location. I shudder to think what it would be like if you had to wait an hour with your sick child. With that caveat, if you don't need lab work on a weekend, I wouldn't hesitate to go to this OneMedical location and expect their usual high quality of service and care.

    The Bethesda location for One Medical gets 5 stars from me. I'm surprised that they haven't been…read morereviewed yet. In general, I like the integration of the app & telehealth with the office and the idea of a more personalized focus on primary care that One Medical provides. Specifically, I like this location where the staff are all very nice and welcoming. It seems like the staff really care about improving health and "taking care" of you. I tried out the Chevy Chase location last year and had a bad experience with a shockingly rude doctor that surprised me. If I went into detail about what happened there, you would be appalled. I've been to the Bethesda location a lot and they have been great every time. If I had only experienced the Chevy Chase location, I would have quit this program but I've been consistently happy with Bethesda. I haven't tried other locations but the model is that they are a different experience than your average primary care medical office. They are very prompt, stylish and offer the choice between in-person services and telehealth. Prior to One Medical, I had a less than stellar experience with a primary care doctor in a different system. When I say that I've been consistently happy with this Bethesda office, I don't say that lightly. It is pleasant and convenient.
