Most excellent! I didn't have a single issue with them! Their entire interior (well, the area that is open for patients) was kept clean and well-organized, they are willing to answer any questions and solve any discomfort, they are professional, and friendly! First time having a root canal done there, and before it, was told by many that a root canal was terrifying, painful, etc. I went there, they took care of business, and I have no problem going there for the procedure again!
