Dr. Roach is a professional. Explained my options and concurred with my decision. Answered my questions during procedure. Her assistant Giao was very thorough in checkingI've had a lot of dental work in my 83 years. I would recommend Dr. Roach. She's very professional and at the same time approachable. Also, her assistant Giao (sp) was really very nice.

I was having an old capped molar drilled into to clean out infection. Not an everyday treatment LOL. I wish I had asked ahead of starting for her to explain each step - not that I was nervous, just curious as to all that is involved. I realize many people simply want it "over with" so what I wished I had asked for is certainly on me, not her responsibility but maybe have the doctor ask the patient if they want each step explained?

I've waited two weeks to complete your survey after my root canal treatment. In case there were Issues I wanted to Include them In the survey. I had no Issues! Overall this was a great experience and would choose Dr. Roach and her assistant again. They made me comfortable, at easy and informed. Dr. Sam communicated, explained my situation and provided three options. During the treatment they both would check on me. They both worked well together on my behalf. At the end and review Dr. Sam even made a few written notes for me that I could refer to later If needed. Thanks to all from the referral, phone scheduling, front desk, dental assistant and Dr Samantha Roach. You are appreciated.

The only thing I would have preferred is more explanation of what they were actually doing during the procedure. This would not be detailed step-by-step. We're through the crown", "I've suctioned the infection from the canal", "you're doing great", halfway there", "crown looks good, I'm going to fill the hole" would be helpful. I realize (and appreciate) the 75 minutes was on the short end of expected time, but it seems forever when you don't know how much time is left! I am not asking for "chit-chat"; I absolutely appreciate that Dr. Roach was focused, concentrating on her work and the assistant was fabulous as well! An option for earbuds with music playing would be nice, I think.

Dr Roach and her assistant were so kind and made me feel comfortable in spite of feeling anxious about my root canal. I experienced a fair amount of pain after my appointment due to a significant amount of infection cleaned out. I called Dr Roach she responded quickly and was kind and so attentive to my concerns about the pain I was experiencing and prescribed a short term pain med. I can't say enough good things about her expertise and ability to make her patient relax during a root canal. Her assistant was also wonderful and caring and checked how I was doing during the procedure. Kudos to both of them!!

Not only did I have a great experience with the Dr/tech, the person working at the front desk was SO helpful. They called my insurance and printed off information so I could understand my coverage and exactly what I would owe. They were willing to schedule me into January so I would have partial coverage through my insurance instead of paying all out of pocket.

The experience was great. I came because a file was stuck in my root from a root canal at my regular dentist. Dr Roach and her assistant were very professional. They be were kind and calming to me. Very thoughtful with their approach. Not a lot of banter between them, just all business. They were efficient and things seemed very cleanly and neat in the room. Everything they needed was right where it needed to be. The outcome was not as I had hoped, but their kindness and professionalism was really valued by me.

The experience was excellent. They checked in on me multiple times to make sure I was doing ok. I cried a little bit at the beginning of my appointment because of the frustration with my experience at my regular dentist office.

I wish Dr. Roach had provided a bit more information about what she had seen while treating me at the end of our visit. I was a bit curious about how things looked, it it was pretty routine or challenging, andante reassurance that they saw issues once they were in my tooth that a root canal was warranted for. But it was a long appointment and I'm sure she had other duties to fulfill afterward. I also didn't think to ask the questions while there so I take most responsibility.

Both Dr. Roach and her dental assistant were incredibly kind and reassuring for me at every step of this procedure. I have some pretty severe dental anxiety, cried a little, and was very nervous. They both comforted me and talked me through every step in an encouraging way that made me feel very calm. I also did not feel any embarrassment about my anxiety - both individuals were so understanding and caring. Would absolutely recommend!

I was not nervous due to the fact, initials welcoming erased. There was excellent team work. Very caring and professionally done. The receptionist seemed very knowledgeable. Will not hesitate to recommend this dental office. He showed me an estimate and agreed to send In claim before I pay per my request. The entire team was Instrumental getting my dental work done. I was very satisfied, I wanted to express my gratitude right there but thought of this survey to do so. I was impressed.I even gotten a F/U call from the receptionist. He even offered to help me connect with my dentist, after making umpteen calls without anyone answering.

When prepping me and gathering information before Dr. Roach enter the exam room, her dental assistant was caring, personable and gave me confidence that I'd made the right decision to use this dental practice for treatment. Later, when receiving anesthesia injections, they could tell I was tense. Dr. Roach said a couple of times, "Keep breathing," and her dental assistant placed a reassuring hand on my shoulder. I appreciated those gestures.

Dr. Roach put me completely at ease. She was kind, thorough, and compassionate, both when discussing the problem I had with my tooth, and in pausing to check in with me during the root canal. She also kept me updated on her progress during the procedure which kept me calm.
