Dr. Nicholson and her staff are absolutely amazing! So amazing we travel 3 hrs to see them. Her genuine care she provides our child is something we don't experience anywhere. She has helped my child in so many way. My child is 17 years old and she won't let us make any medical decisions unless we talk to Dr. Nicholson first. It has been a blessing to work with such a caring staff. Any questions are answered promptly or we are told where to go or whom to contact. The nurses are so kind and the social worker makes us feel like family. Thank you so much for all you do! You and your staff are 4 in a million. ?
