"I was the fix-it man at home growing up. I loved to take apart (and put back together) every old device I could clocks, radios, engines, and put together models, kits, blocks, and erector sets. If there was anything broken or malfunctioning, mom or dad expected me to fix it. I found pediatric spinal deformity to be the ultimate clinical application of technological advancement in orthopedic surgery. Particularly because of the critical and sensitive spinal cord laying within!! Many of the procedures used routinely today for pediatric spine problems were not even considered possible 25 years ago when I was in medical school or residency. I guess one might think of it as being able to use the ultimate erector set to rebuild childrens spinal columns around the spinal cord. WOW! I couldnt have imagined when I started medical school being able to do the things I do now on a daily basis. On top of that - I just love taking care of children."

Walter (Wally) Franklin Krengel III, M.D. (Wally): Orthopedic Surgeon; Chief of Spine Surgery at Seattle Childrens Hospital. His specialty interests include; pediatric spinal deformity, pediatric cervical spine instability; congenital deformity as well as general pediatric orthopedic trauma. Dr. Krengel is a member of the American Academy of Orthopedic Surgeons, the Scoliosis Research Society and the North American Spine Society. He has been on staff at Seattle Childrens Hospital for 25 years.

Dr. Krengel is a clinical associate professor in the Department of Orthopaedics and Sport Medicine, University of Washington School of Medicine. He completed his undergraduate degree and his M.D. at Stanford University. His internship in general surgery and residency in orthopedics were completed at the University of Washington. He also completed a fellowship in spine surgery at the University of Washington. Dr Krengel has a great love of the outdoors and when not in surgery can be found fly fishing, skiing, golfing, chopping wood, or even digging holes, as long as it is outside he is there!

    If you have a child with Scoliosis you could not be in better hands than with Dr. Krengel! I use to work for him a few years ago and know this for a fact. He was the first doctor to tell me I had scoliosis! I was seeing him for a painful hip and I had no idea I had adult Scoliosis! Unfortunately for me, Dr. Krengel does not treat adult scoliosis any longer. But take it from me, you will be getting one of the best doctors ever to treat your child and like I said I know firsthand as I worked with him and saw how he was with everyone. I would totally put my trust in him to treat myself or my kids, no questions asked!

  • Kimberly Edmonds, Washington 10.28.14

    Our son needed surgery for his severe spinal curve due to Scoliosis and Dr. Krengel performed a miracle. Dr, Krengel, along with the staff at Seattle Children's, took such amazing care of our son before, during and after surgery. It is apparent to us that Dr. Krengel thoroughly enjoys working with children and we couldn't have been more pleased with him or his talents as a surgeon. Thank you Dr. Krengel!

  • Renee Mount Vernon, WA 01.01.14

    Dr. Krengel is a ROCK STAR! After our son was injured in a rugby game last Spring, he was thought to just have a neck strain. But when symptoms persisted, our pediatrician sent his X-ray down to Children's for a look....and thank goodness she did! Zach had been walking around for a week with a broken neck! Dr. Krengel's team did an amazing job of first - calming the very stressed-out mother down! - then explaining the surgical procedure step by step, getting him stabilized and comfortable, and were able to perform the surgery using the least invasive procedure. He has made a full and rapid recovery and we have Dr. Krengel to thank! Not only is he an amazing surgeon, but his compassion, knowledge, and open communication style are top notch! Thank you Dr. Krengel & Children's!!

    My daughter was diagnosed with mild scoliosis which then progressed to severe scoliosis in a matter of months. Her only option was surgery. Dr. Krengel came highly recommended and we were not disappointed. He did an amazing job. Both he and his wonderful staff took great care of us and my daughter. Neither myself or my ex-husband have a medical background; Dr, Krengel took his time explaining everything in a manner in which we could understand. He has a strong and reassuring presence which is very helpful when you are in a situation that is beyond your control. Two years after surgery, my daughter is back to normal. People are always surprised when they find out she has had spinal fusion surgery. If we had to do this over again, I would choose Dr. Krengel without hesitation to take care of my baby.

  • Victor Seattle, WA 12.01.11

    I was suffering from severe spondylolysthesis. Dr. Krengel took the time to explain the problem, and the options available to me, and was genuinely concerned for my well being, and if not for his work, I wouldn't be walking today. Dr. Krengel is a great surgeon and recommend him highly.

  • Kim Olympia, WA 06.06.11

    My daughter had a 4 level spinal fusion for scoliosis in Dec of last year. She had it done at Seattle Childrens Hospital by Dr. Krengel. She has had abolutely no issues at all. I would highly recommend Dr. Krengel. He did an amazing job. She is a dancer and gymnist and is already back to dancing and doing cartwheels and roundoffs, 6 months post surgery. He is a very humble and caring Physician with years of experience and was recommended to me by other Physicians. If you have a child with a spinal issue there is no one better!

  • Jennifer Tacoma WA 04.04.11

    My daughter recently found out that she had a broken neck. Dr Krengel was very thorough and decided that she needed surgery as soon as possible. He was pleasant and well informed about the whole process. I have never had a doctor call me to check on my child before and afterwards Dr. Krengel did his normal rounds but when we went home after surgery He and his staff called several times to see how my daughter was doing. I would recommend him fully if you have a problem with the spine.
