Office staff, techs, and nurses are great; however Dr Johnson ability to listen to the parents and diagnose issues is what I have a problem with. 2 years and over a $1000.00 and my daughter is worse and still do not have a diagnosis of her issue. Because I complained to Dr. Johnson, now he listens and says I dont deal with issues like that, I can refer you to Vanderbilt in Nashville. Wow thanks for the help, enjoy the payments on your boat!

Utilized their walk-in clinic to get an EKG. We were in and out in 15 to 20 minutes. They made it very easy.

Dr Johnson is an incredibly gifted physician.We are very pleased with his care, vast knowledge and level of service. I highly recommend him!!!

Always a pleasure going to the cardiologist. My son has been a patient of Dr. Johnsons for about 6 or 7 years now, so this review is an overview of that time. Dr. Johnson has always been very thourough and informative of heart issues. He is also, super kind and genuine😊 His new office on Lee hwy is pretty cool. All of my kids want to tag along, just so they can hang out in the waiting room.Theres toys and activities, (in waiting room and patient rooms)for all ages and even a cool aquarium! Were so glad to have found such a great doctor and location as well!

This is the most caring doctors office Ive been to. The doctor always calls back quickly. He is very patient and understanding. He also works well with my son. I highly recommend them.

We have been with Dr. Johnson since he came to Chattanooga. You are not patient #876 but a person with a name who he remembers and doesnt have to ask you all the same questions he asked at the last visit. Hes great with my daughter, he talks to her not at her. Hes the kind of person you can see yourself just having as a friend. Their office is very clean and kid friendly. The staff there is just as nice as can be and dont treat you as if youre bothering them when you call and ask questions. If you have a choice this is the place you want to bring your child!

Dr. Johnson takes time with his patience. He explains things in detail and allows questions. I recommended him to many people.

Doctor Johnson has been my sons physician since he was born. He started seeing my son in the NICU at Erlanger hospital. We have since followed doctor Johnson to his new office location (All Heart Pediatric Cardiology). As a cardiologist who was a baby with a heart condition himself he is very attentive and compassionate. Doctor Johnson takes the time to listen and explain things during the office visit and always asks if theres anything else he can do for you. This means so much considering its hard to find great doctors like this anymore. I trust doctor Johnson treating my sons heart condition completely. He is wonderful with children and always listens to my husband or myself if we have thoughts, questions, or suspicions regarding our son. He is a very caring and compassionate physician, I wish all doctors were more like him. All in all if you want a wonderful, caring, compassionate, and attentive pediatric cardiologist I recommend you see doctor Johnson, he is the very best!

Dr. Hays was great! He was so thorough and explained everything to us. We were seen quickly.

Dr Hays is amazing And the office is very nice and kid friendly!

Great place for newborn

Great doctor
