Dr. Fedderly was incredible and took care of my son last Friday. He really took the time to explain my son's tests and what he was hearing on his heartbeats. I am grateful for his expertise and the ease in which he explained everything to me. ..I would recommend him to anyone.

I have both worked with this Doctor and for the past 10 years he has been my daughter's cardiologist. She does extremely well for her diagnosis and I attribute a great deal of that success to his level of care for her and our family. He is always willing to devote whatever time the patient or family needs from him not only for diagnosis, but support as well. He was a huge support in my career as well when I decided to become an RN in pediatrics. There are not enough words to describe the dedication and care Dr. Fedderly provides his patient's, there families, and colleages. We will be lost when he retires.

dr federly diagnosed my son carson with aeortic valve stenosis when he was 8 months old. as being a mother, and thinking you are just going in for "testings" and the outcome of it all being very serious, it can be very scary. and i was at first. but dr fedderly and his nurse katie were very good to us. they made sure that i fully understood everything about carsons diagnosis, and what was going to need to be done to help this. we scheduled a surgery date ( one month later) Bottom line is this, they have always been so quick to get back to me with questions, concerns, etc. During my sons surgery, everything, they have been more than wonderful. i want to also mention his surgeon was dr tweddell. I would give my life to to these doctors. They are the reason that my son is doing so great!!! (my son just turned 4, and is doing fantastic!! only one surgery so far..and thats just wonderful!!!!!!!)

My 6 month-old son is a patient of Dr. Fedderly's. His nurse practitioner, Mary, and him are very thorough in making sure we understand everything that's going on. They treat us like we're family. Very caring. I would highly recommend Dr. Fedderly to anyone else!
