I've wondered what had happened, and hoped he would be back soon. I'm so sad to hear about this and wonder how you found out about him! My two sons only had Dr. Cohen as their doctor. I had hoped they'd be able to grow older with him as their doctor. Treasure each day with the ones you love. I wish Tx. Children's could be honest with us... and now that we have to find new doctors, they're telling me some aren't even accepting new patients, which irritates me!
