About Waterfront District Dental
Downtown convenience and a steady flow of adult patients transferring mid-treatment mark this office, with Dr. Marshall and Dr. Bart Knowles handling day-to-day care.
Waterfront District Dental is a general dental practice in downtown St. Petersburg that also offers Invisalign and clear aligner treatment. A notable share of reviews come from adults and from patients who moved their care here mid-treatment from other offices, many citing the walkable Beach Drive location as a draw. The office itself comes up often as modern and spa-like, with gentle handling of extractions and fillings noted for patients who feel nervous about dental work. Both Dr. Marshall and Dr. Bart Knowles are mentioned regularly, with Knowles's arrival described in several reviews as a marked improvement over the previous team.

Look I know you are on here reading reviews to see if this is the right dentist for you. Stop right here. Imagine me a semi pro offensive lineman so scared of the dentist i was literally shaking and had tears running down my face like the first time you saw the notebook. (Ive never seen it but thats what i heard.👀 But stick with me) Fast forward 1 hour later im on my way home after the easiest most painless extraction I have ever had and saying to myself I can't wait to go back for a cleaning. Yep that's the kind of dentist you get by choosing Waterfront District Dental. Dr Knowles is the kindest most understanding and patient dentist i have ever met. I was more than just a patient i was a human being to him. He went above and beyond to make sure i was at peace and calm before he took better care of me than my own gam gam after my first heartbreak. A Review can never explain the truth of how important it is that you choose him. Im not saying Waterfront District Dental will solve your life problems but I guarantee your dental needs will be one less problem for you. Take the time make the call let Marie schedule your appointment and leave the rest to him and his amazing team and tell him Kevin sent you. Im telling you right now you will be thanking me afterwards and your welcome
