Dr. Blum is WONDERFUL!!! This was my first visit-- and besides being very welcoming and caring, Dr. Blum was extremely well prepared- she came knowing all my information and tests. She asked insightful questions and listened to me-- she was interested and I was VERY grateful that she wanted to understand my concerns. Then after this review and discussion of my pain and situation, Dr. Blum also did a thorough exam. Dr. Blum makes real the concept of a knowledgeable, wise and caring physician She gave me great guidance and very helpful Information In writing. Her whole manner of patient care was BEAUTIFUL. I am so grateful for the guidance I received in finding her!
