Saved my life 2 years ago.Went to ER Doctor in a top univ.hospital on Saturday--who said that my vomitting was due to an obstruction -come back on Monday to see a ERCP dpecialists. Called Dr.Mullick who agreed to do ERCP on Saturday evening--but he did tests-which revealed an infection was causing vomitting and it had already affected liver etc.He called in an infectious disease specialist immediately as he thought it was urgent. Later on Sunday he called in 2 other specialists as my breathing problem worsened. No ERCP was needed--he did not charge me much and came 3 times to see the progress. I am impressed with his diagnostic ability--he did not accept ER Doctor's diagnosis .I highly recommend him.
