5/5
I'm so happy to have found Dr. Kahn! He helped me understand why my gastrointestinal system is sensitive and what chronic stress can do to your organs, This propelled me to dive deeper into the root cause of my issues. Now, I have the knowledge, tools, and gastroenterologist, to live a full life with this stomach and nervous system I have! Thank you for looking deeper, Dr. Kahn. Be Blessed!
