    This is the first doctor's office I have felt completely, 100% comfortable at here in D.C. I began…read moreseeing Dr. Elizabeth Nerbun (who was also a nun!) but she unfortunately moved away. I was extremely apprehensive about trying one of the other doctors but every single one of them have amazing reviews. They reminded me a lot of my own parents, who are internal medicine doctors. I saw Dr. Dennis Cullen and was pleasantly surprised at how much I actually enjoyed my visit! I have been overweight literally my entire life and I dread visiting the doctor as many who don't know me just automatically assume I don't exercise and am unhealthy in my food choices. Dr. Cullen made me feel so at ease and didn't even mention my weight. It was nice to come out happy knowing I'm doing the best I can and to just keep trying. Life is hard enough as it is! Their nurses are all very kind, especially the nurse I saw today. He was so funny and made great conversation. The front desk staff are business-like. The only reason I am taking one star off is because of the yearly $45 "clerical fee." I've noticed many D.C. doctors are adding a fee now and as someone who only sees the doctor once a year for a physical, maybe twice, it makes you not want to have insurance. If this was $25 or so, I wouldn't feel as annoyed about blowing $45 on a fixed budget. Anyway, I highly, highly recommend these doctors! For the first time in a long time, I think I found a place I'll stay.

    I'm a huge fan of Dr. Cullen! He's been my doctor for 15 years and I recommend him to everyone I…read moreknow. Always on time, personable, knowledgable and beyond hilarious, Dr. Cullen is the type of physician most people wish they could have. I can't say enough good things about Dr. Cullen. If you are looking for a great doctor, he's the best!!

    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.
