11/23/2025

Dr. Guastalli as well as the Resident seemed to have quality care at the forefront. They asked questions, showed they were concerned and I felt like I was genuinely heard. I did not feel that I was rushed or being pushed along for time constraints. Any questions I asked were met with respectful answers and I felt involved and that I was given all of the options and supported in what path I would like to take going forward.

Dr. Nick is learning the banjo!! I expect a hootenanny next time I come in!

08/29/2025

So even though I provided a good review based on the given questions, the doctor failed to order any routine lab work as part of my annual checkup. Even after asking about this, the nurse simply said that there are no lab orders and will be given as needed. That is absolutely ridiculous. Routine lab work should always be requested for an annual exam.

I think Dr. Guastali is a very good doctor. Good explanations and visits never feel hurried

Good
