Dr Mary Peterson is one of the most caring, patient doctors I have ever seen. I wish all my doctors were like her.

Dr. Peterson was very understanding and gave me different choices for my problem. All staff worked together to make it a pleasant experience.

I just love Dr. Petersen and her staff. Her nurse Karen has been with her since I became a patient in that practice. She is very kind, warm and caring as well. I have referred several of my friends to Dr. Petersen.

Dr. Peterson has provided me with excellent care and is sensitive to my health needs as well as how it affects me personally. I have unequivovally recommended her to other post menopausal women. I feel fortunate to have her as my GYN. I have had bad experiences with other Doctors I the past and was relieved to find someone as dedicated as she is.
