I love Dr Underhill. She is absolutely a rockstar and I literally suggest her to everyone I know. Every provider and nurse and office worker is the best. I feel genuinely cared about and loved at her office. I’ve never felt silly for bringing up a concern, I’m always taken very seriously and I’ve never been disappointed or let down.
