    I originally started coming here after I moved to the area and received a recommendation for Dr…read more Bruce Schneider from a co-worker who lives in the area. He and his staff was a great. After he retired a few years back Dr. Reina Garcia took over. Typically I would shy away from a new dentist due to poor previous experiences as a kid, but I am glad I decided to give Dr. Garcia a chance. She is just as friendly, gentle and approachable. Best of all the staff (Anne, Tracie & Evelyn) never changed and are still very friendly and receptive to questions. As of this review I have been coming here for the past 6 years for my bi-annual cleanings and check- ups. During this time, I have moved further and further away but still come back here every six months because I feel comfortable which is very important to me.

    Dr. Garcia is a gem. I don't like going to the Dentist. I admit it. But, since I have been going…read moreto see Dr. Garcia, I actually kinda, just kinda, look forward to it. First of all, she is a skilled dentist and has handled a series of problems for me. She is always kind, gentle and makes you feel comfortable and attended to. This is not an office with a lot of hustle and bustle. It is just Dr. Garcia and her assistants. Everyone in the office is friendly and knows their job. I cannot recommend her highly enough. She explains everything as she is doing her work and I won't go anywhere else.

    Dr. Thomas was incredibly precise. I am very happy I found a knowledgable and gentle dentist. 10/10read more

    Personally would try and find another option for dental care if possible. The front desk staff are…read morenice and the hygienists know what they're doing. However, I would be careful about getting seen by certain dentists at the practice. I historically have taken very good care of my teeth. Only had 1 small cavity in my life up until coming here, and my past dentists have always remarked at how well I keep my dental health in order. However, every time I have come here and seen Dr. Thomas, he has claimed to be finding cavities. The first time he told me I had a cavity, I let him fill it because I have always believed in trusting dental professionals and figured he probably saw something that I didn't. The filling experience was fine, he did a good job. I was more angry at myself for not taking better care of my teeth. I went back to see Dr. Thomas for my normal 6 month follow-up cleaning. Made sure to really brush and floss well in the 6 months between seeing him to ensure there was no cavity this time. Got seen by the hygienist who told me my teeth looked great and it would just be an easy cleaning job. When she finished, Dr. Thomas came in to look at my teeth and boom, all of a sudden I had a cavity. Immediately I became suspicious. He offered to fill it that day, but I told him not to bother and I was getting a second opinion. Went to see someone else and told them about my alleged cavity, and after looking at my teeth they just laughed and said they had no idea what he was seeing. My teeth were perfectly fine, as I suspected. I did go back to Sudbury Dental Excellence after a year, but requested to see a different dentist in the practice. I was curious if for the 3rd time in a row they would find a "cavity". Saw a hygienist and then a female dentist this time (can't remember her name unfortunately), and she didn't find anything out of order, even in the spot where Dr. Thomas had "found" something a year prior. Bottom line, people there are friendly, office is clean and inviting. Dental expertise seems a tad lacking.

    Dr. Maria Elizondo is truly a magician. I was referred to her 30 years ago by an acquaintance who…read morewas an oral surgeon, who told me she was the best. And there's no doubt about this. I am now in my sixties, and I had major pediatric dental trauma from my childhood. Dr. Maria changed my life, enabling me to access dental care without fear. I had a crooked front tooth that marred my smile, which made me embarrassed. Dr. Maria told me she could cosmetically fix it. So I have had a beautiful smile for nearly 30 years, thanks to her wonderful work, which only took an hour or so in the soothing environment of her office. She has protected my teeth and my health for so much of my life. I cannot express my gratitude deeply enough to her and her wonderful associates.

    Front desk was very friendly with booking and check in. Unfortunately, beyond that my 7 year old…read morefelt very uncomfortable during her cleaning. The entire experience felt off, rushed and awkward. The hygienist did her best but I felt was inexperienced in her efforts to work with a child. We ended up not seeing the dentist we were told we would (by both the front desk and hygienist at the visit), there was alot of confusion and not a full comprehensive exam by the dentist, the owner who I think was asked to just step in to help. My child left in tears and was given an adult toothbrush and adult toothpaste and no prize, which for a child at a dentist office is the highlight.

    This pains me to do this as a customer of 15 years at this practice but this is NOT the same…read morepractice I came into. Dr. Putt has been spending too much time on the golf course (at least that is the explanation by the technicians to why I have not seen him the last 5 years). The front desk now is incredibly rude and condescending. If you don't have the right insurance, get out, if you have a question, we don't have time for this. The last hygenist I saw was yelling at me the entire time, and telling me all about how much her life sucks. The hygenist I saw for many years who was amazing left the practice unfortunately. And when I first joined they were willing to work with me on a dental plan that works for me. Now it is aggressive treatment and pressure sells that requires X-rays every 6 months and deep cleanings. If you don't like it, I was told by the front desk to GET OUT. Ok you got your wish, good riddance.

    Do yourself a favor and switch dentists before making your next appointment. My entire family has…read morebeen clients of Wayland Dental for over a decade, and they are NOT the same practice. I just took a new job and have to move out of state. I was overdue for an appointment and worked with the team to squeeze in before my move. They have a new receptionist team that is incapable of running this business. They rescheduled and kept playing musical chairs with their clients appointments trying to move them around. I just went in for my appointment finally, a few days before my move- for them to tell me they do not take BCBS anymore and would charge me $450 for the appointment. When asked why I wasn't notified of this , they claim they had Delta Dental on file for me. (Later when I called back- I told them my appointment in December with BCBS and they confirmed that is who they billed out.) For months I've received emails from them telling me I was due for an appointment and to call and schedule. NOTHING about no longer accepting BCBS. I left the office so upset and called back to speak with the supervisor, Crystal. She was just as incompetent as her team. She said "if it was that big of a deal, they would have billed out to BCBS and had me mail them the check..." when I clarified that she meant bill, she corrected and said check. She wanted me to pay my insurance for seeing them out of network, and then wanted me to pay THEM whatever portion of my appointment that insurance would cover... wow they truly care about the customer... I requested a call back from Dr. Putt and plan on telling him what a disaster his team has become. When it was him and his one front desk receptionist, they might have been short handed- but they were good and actually cared and had their sh*t more together than they do now. Now I have wasted time making appointments, going to an appointment I had to leave, talking to them, crying in my car, and writing this post- all to be moving out of state with a new job, stressed as can be, and overdue for a dental appointment (after getting completely screwed over by the practice my family and I have given business to for over a decade.) I am beyond upset, and cannot advise others more to find a different dentist- this is NOT the same practice that it used to be.
