- 5.0Aug 15, 2026Dr. Grundy provides exceptional care and always goes above and beyond to meet my family's needs. She is incredibly attentive and genuinely cares about the health and well-being of my children. She even followed up on my child's blood work while she was on vacation, which truly speaks to her dedication and commitment to her patients. We are very grateful to have her as our doctor.

- 5.0Jul 17, 2026This provider has been my two kids primary care physician for over 19 years. The very best at what she does, her demeanor is very calm soothing gets along very well with children. They are very comfortable and opened up very easy to her. My kids love going to their pediatrician because it's always a fun time talking about their health and overall well-being. I highly recommend this provider your kids or child will love her.
