I can't say enough about Dr Howell! She is professional and compassionate and most importantly, empathetic! She works quickly and efficiently but takes the time to evaluate and diagnose so you never feel rushed even if she is crazy busy!

Dr. Jenny Howell and her team at Green Leaf Dentistry are unparalleled professionals. They ensure that you are entirely informed about the procedures you are having - what they will entail, why they need to take place, and what to expect afterwards.
