Service is top notch. From check in through the procedure, I felt valued and taken care of. I really like that every step is explained ahead of time and care is taken to make me as comfortable as possible. Procedure was very smooth. Personal call from Dr. Rosania later in the day was much appreciated. I highly recommend this practice.

On behalf of Silvana Da Cruz: I had an outstanding experience with Dr. David Rosania and his entire team. From the moment I walked into the office, I felt welcomed and cared for. Dr. Rosania is truly excellent at what he does—his attention to detail, thorough explanations, and calming demeanor made a potentially stressful procedure feel completely manageable. He takes the time to ensure every step is done with precision and care, which speaks volumes about his commitment to high-quality patient care.

I was particularly impressed by how meticulously he planned and executed my dental implant procedure. The results exceeded my expectations. If you're looking for a Periodontist who is both highly skilled and compassionate, I highly recommend Dr. Rosania. You're in great hands!
