I believe Dr. Nierenberg saved my life!

I was in DR. David’s office for my yearly health assessment. I believe i was 79 years old . He told me i needed to have a colonoscopy since it had been several years since i had one. He recommended a doctor for me to go to. The doctor found a pre cancerous polyp and removed it. I am thankful to Dr. David, i believe he saved my life! He also has been a good friend to my husband & i. He is the Best!!
