2 years ago,went to a top univ.hospital in Chicago on Saturday as my vommitting was getting worse.ER doctor said-you have an obstruction-come back on Monday to see an ERCP specialist. I called Dr.Mullick who agreed to do ERCP at Delnor Hospital on Saturday. Upon arrival,he and other internist decided to do some tests.They found that I had an infection--that had affected my liver etc. Dr.Mullick called an infectious disease specialist and later 2 other specialists to check my breathing problem.He decided no ERCP was needed--he did not make much money on me. I was impressed by his thorough diagnostic abilities.He sacrificed lot of his time on Saturday for me for very little money.He even came and saw me for next 3 days for no pay. I highly recommend this doctor.
