Great experience! Very knowledgeable and helped explain many things that I didn't know before. Very clean facility, kind staff. Next gen technology that helped 3D map my teeth which was pretty cool.

Dr Lansdell’s office called me immediately after I requested an initial consult and cleaning via Opencare. They fit me in the same day. The entire staff at Dr Lansdell’s office were genuinely caring and easy to talk to. Dr Lansdell, himself, took his time with my consult, is a wealth of knowledge and answered all my questions patiently and informatively. I was exceptionally impressed with the entire experience

It was a very nice, modern & clean facility. All staff members were very professional and knowledgeable. I had a great experience.

Very nice dental office. Direct billed my insurance and even double billed the rest to my partners. Didn’t need to pay out of pocket!

Dr Lansdell was by far the best dental experience I have ever had. He was thorough and caring. He explained everything well and made sure to check with me both to make sure that I was comfortable and answer any questions that popped up.

My first appointment with Dr.Lansdell went very well. He described what needed to be done in layman’s terms and his staff were very friendly . Look forward to my next appointment

Very sweet man! Super descriptive about everything, informative but also supportive and reassuring I’m doing a good job with my hygiene!

Super kind and he definitely knows what he’s talking about! He explains everything so well.

I recently visited Dr.Lansdell because my permanent retainer placed by an orthodontist had come unglued from my teeth and had left a sharp spot in my mouth. His team was able to give me an appointment ASAP given the urgent nature, squeezing me in before their holiday break. He explained his plan to re-attach the retainer and walked me through the procedure. His team was very professional and prepped me for the procedure so that it was all done perfectly and very fast. Best of all I left no longer in pain :)

Awesome dentist, very informative and friendly. Nice staff too. 10/10

Friendly, knowledgeable, and a good sense of humour which made the whole idea of going to the dentist much more manageable. Definitely will be coming back here again.

Very knowledgeable and provides good support in terms of how to structure your required treatment.

Great experience! Team was attentive and welcoming. Appointments were easy to confirm.

Was there for an overall assessment with regards to a broken portion of a tooth. X-ray was taken and assess then options were given for treatment. A very thorough examination was given.

Very nice, knowledgeable person to speak with. always explain the reason behind the "scene" and patiently let me know why those steps are always necessary to go through. I have done the cleaning, filling.

Nicely explained current situation in details and future procedures, considering my insurance coverage

I had my check up and cleaning first, replaced a few fillings and discussed my path for my perfect smile. It has been a great experience.
