Dr. Buchanan is top-notch! He clearly knows his stuff - and he's personable. Highly recommend!

Dr Buchanan is the best! I fractured my ankle and he accommodated me very quickly to schedule a visit and then surgery. He took the time to carefully explain what he was seeing and what should be done. He was confident but not in any way overbearing. I was nervous for surgery but I felt very confident in his abilities. Now two months post-op my fracture is healed and the incision is so clean. The office is very very busy so scheduling is tricky and you'll usually wait a while but it's worth it. I can't recommend Dr Buchanan more highly!

Dr. Buchanan was recommended to me for the topaz procedure for chronic plantar fasciitis by another surgeon who had helped me before. So far I've been very happy working with him. He is friendly and knowledgeable. I do usually end up waiting at least 30-45 minutes to see him however it's always been worth the wait.

I scheduled an appointment with this doctor and I got to the appointment 5 or 10 minutes late because I was at the hospital learning that my mom has terminal cancer. I called them 10 minutes after the appointment from the parking lot to find out how to get up to their office since it was unclear since the office is located at the hospital. She told me they had A 15 minute no-show policy and that we would have to cancel the appointment.

When I reminded her that I'm only 10 minutes late to my appointment, she still insisted on rescheduling even though I had not exceeded the 15 minute no show window. Then I went on to let her know that I'm only a little bit late because I just came from Fairfax hospital because my mom this morning was diagnosed with terminal pancreatic cancer. I was even still wearing my visitor badge from the hospital.

I asked him if they could please cut me a break and have a little sympathy on me and yet she still told me I couldn't come to the appointment even though I was within the 15 minute window. Needless to say, I think I dodged a bullet. This practice clearly doesn't care much about their customers and I'll head over to one of the other more reputable practices. I had only scheduled an appointment here because they were the only one that was available.

Not sure why the staff ignored my follow-ups for months with no acknowledgement, but I've never seen such lack of professionalism from a practice. One doctor in this practice referred me for an operation to another in the practice, and that doctor's staff lied repeatedly and became non-responsive for months. Maybe they're good if you can get through, but I had to find someone else.

Is Nirschl Orthopaedic still employing domestic abusers like Dr. Walter's administrative assistant Sarah Elizabeth Jajosky Cogan?

Very organized and welcoming office. Dr. Buchanan is so knowledgeable and has excellent bedside manner. The experience makes you wish all doctors and offices treated patients like this.

He is so popular and so busy he needs two receptionists. On my first visit he was extremely patient and listened to my history and concerns. I feel very confident about having him do my surgery. However his office thinks they can always call you back rather than answer the phone because they are so busy. They need to understand other people have the same problem they do and may be difficult to reach that way

I waited about an hour and 15 minutes before seeing the doctor, Dr. Buchanan. Once I was able to see him, it was a wonderful experience. While in the waiting room I heard another patient check in after me with the exact same appointment time as me. And she was brought back and seen before me. The wait time was the only unpleasant thing about the experience. All The staff were great and the doctor was extremely knowledgeable and helpful. I have hope that my ankle will be healing soon!

I really appreciated Dr. Buchanan's expert and thorough exam and specific, practical recommendations. It was the first time in the many years since I've been bothered by my chronic ankle sprain that I felt it was treated fully - from x-ray assessment to immediate, short and long-term plans to improve it. I didn't feel rushed, all my questions, were answered, and Dr. Buchanan clearly is both an expert and passionate about his work. Highly, highly recommend.

Dr. Buchanan showed me on the x-ray my ankle injury and clearly explained the injury and the treatment. He provided a printout of instructions and emphasized and highlighted the most important points. He thoroughly answered my questions. The medical assistants were very helpful in suggesting a way to get positioned for the x-ray with minimal discomfort and showing me how to put on the boot and then had me actually do it for practice. Great care.

I write this note from a place of deep gratitude for my treatment as Dr. Buchanan's patient. This time last year, I was seeing Dr. Buchanan to overcome a bad high ankle sprain in a D.C. theatre. The thought of losing my ability to do my job well and live life without a persistent injury was intensely painful. I grew up and trained as a dancer and actress, so using my full range of movement is of the utmost importance to me. Recently, I've been living in Massachusetts and realizing just how far I've come.

I've hiked a great many miles in the mountains up here, and have been practicing yoga every morning. Although I haven't attended a dance class again yet, I have all the confidence I need to do so. I thank them for all the adventures I've had since last fall, and for all those I will have, painlessly. I remember coming into Dr. Buchanan's office scared and distraught.

He and the Nirschl staff were kind and supportive of me and my recovery goals at each appointment and over the phone. I thank them for the care I received, as it is exemplary to their profession and humanity. My complete physical and emotional rehabilitation from this injury is owed to them.
