The folks at Northeast Foot and Ankle are great! The staff were very kind and knowledgeable. The new patient process was very easy to do and they offered the ability to do it in advance on the portal. My appointment was on time and I was out in under 45 minutes.


Very happy I chose Northeast Foot and Ankle! Dr. Sartori and the entire staff are very attentive and knowledgeable. I had a bunion removed and from my initial appointment, through the surgery, and to the last follow up I always had a great experience. I highly recommend this group!


Total experience rates a 10. Dr. Baczewski was the epitome of what a medical professional should be. She offered a choice of options to alleviate my foot pain. Once I opted for surgery, the process went smoothly both in the surgery center and the office for post operative laser and follow up. The entire staff was welcoming, courteous, and highly trained. The facility was easy to access with ample parking. The online reminders for appointments was also a plus.
I would highly recommend Northeast Foot and Ankle.


Both doctors are excellent practitioners who explain things upfront and do not try to upsell/push unnecessary services. I recommend laser treatments if you have persistent warts.
They also saved my baby sister’s life when the ER doctors wanted to send her home while she had a huge infection on her heel—one call from Sartori and she was admitted for three days and got the right treatment. She turned 21 this summer ☺️ these people care and do a great job!!
