Patient Comments (2)
Columbia, MD |
We have a son with complex GI needs and she spent a solid 45 minutes+ understanding his complexities and providing logistical next steps that were non-invasive. I would recommend her for any parents whose children may have complex GI issues.
in Owings Mills, MD |
She was prompt, professional, and thoughtful. I highly recommend her.
