Dr Derby is really kind. What I really like about her is that she is always willing to solve any questions or doubts you might have. She never seems she is in a rush like most other doctors at the same practice.

She was great, as was the initial nurse.
December 13, 2025
I appreciate that Dr Derby stopped in to let me know she's delayed but would be available as long as I needed to answer questions. I came her after 20 years at [...] for a variety of reasons, and the staff patiently listened to my questions and concerns. I wish I'd come here sooner. It would have prevented a lot of frustration I felt while at NW.
