This is in regards to my father, Tony Lao. His date of birth is 1-22-57. Please have someone contact me regarding his gastroenterology referral for a colonoscopy ordered by Dr. Jennifer Evans. I have been trying to reach the referral dept for weeks and left messages but have yet to get a reply. We are unable to contact the gastro office the number you gave us is invalid. Please provide us with more information and verify the correct contact information to the gastro office my father was referred to! Thank you!
