My daughter has been a patient of Dr Mckenna since she was 4 months old with frequent ear infections. She is now 14. He and Lynnette Lambert have been nothing short of outstanding in managing her issues and then my son's. We recently saw him for what we thought might be presyncope related to inner ear. He immediately ordered an MRI and further testing and sent her to PCH to see a pediatric cardiologist and pediatric neurologist which is more than the ER doctor did for her in that morning. I'm very thankful for his expertise and trust his judgement completely.
