always friendly staff and thorough exams that address my child's needs

February 13, 2017

Dr. Keljo is the best!!

December 13, 2016

We waited a long time between the time that we got into a room and when we actually saw the doctor. But the care that my daughter recieved was very good.

December 06, 2016

I felt that the Dr. just wanted me to give my child more laxatives and didn't really want to look into the causes of his constipation.

November 01, 2016

I absolutely love Dr. Keljo. He is the most thorough physician, very knowledgeable and caring. If I leave message with Denise his nurse I always receive care right away. Both are outstanding!!

October 26, 2016

Dr. Keljo's nurse Denise is wonderful. Anytime, I email a question through the portal, she responds in a timely fashion and follows up. Dr. Keljo is great. He is a straight shooter, but open to compromise and alternatives depending on the situation.

October 19, 2016

I was asked to arrive at 10am for a 10:30 appointment. we were not seen by the doctor until almost 11:45. no explanation was provided. that is unacceptable. kids should not have to wait that long.

October 12, 2016

Everyone is always so helpful and friendly. Can't say enough good about this office and it's employees.

September 07, 2016

Dr. Keljo is excellent!

September 06, 2016

Dr Keljio went above and beyond seeing us for the appointment even though we went to the wrong office and was late. He gave us the time we needed and didn't rush us and allowed us to ask any and all questions we had.
