Derrick Cox, MD

"Doctor Cox is an excellent doctor with fabulous bedside manner . It is a blessing to have him back in El Paso."

"Experience with Doctor Cox was horrible. He is a liar after he lied about leaving a Gallstine in me. After I went to the ER prior to my follow up and after the ER called him about my remaining gallstone, he lied to me at my appointment with him saying it was a "clasp". I have tried reporting him to the Texas Medical Board even though I have all my paper work stating what was going on with me and sent them copies. I ended up going to a different hospital because this doctor lied to me. IF anyone ends up with this doctor, please record your conversations with this doctor and get EVERYTHING in writing on diagnosis. DO NOT TRUST THIS DOCTOR!!! I don't understand why he is still practicing."

"Not only was this doctor’s demeanor completely dismissive of my husband’s ailment, he did not have any images ready for the appointment, one that was specifically given to my husband by his staff. The consultation lasted five minutes and at no time did he tell my husband he would procure the rest of the needed exam results to proceed with an evaluation of his ailment at a later date. Will never see this doctor again!"

"From the first day i met Dr. Cox he gave me the impression that he was a one of a kind Dr and surgeon. He has guided me through the journey up until my surgery which he handled with care and professionalism. I like to say he is an angel sent from heaven because he has helped me heal from diverticulitis as well as removed my infected part of the sigmoid colon. Other than the Dr being amazing and caring, his staff doesn't stay far behind. Melissa and Lilly have been two of the most amazing people in his office. If anyone is looking for a good surgeon and staff this is the place to go and get healed. Depending on your surgery. Thank you for everything Dr. Cox. From the bottom of my heart."

"This experience at Sierra has been horrendous. My grandfather was misdiagnosed and sent home. Upon return having to wait an hour to receive pain medication on what upon intake was documented as a 10/10 pain! Comments from staff like "No one told me he was diabetic from an RN and CNA" when asking what his blood sugars readings were. Then having a procedure done with what we later found out was done without Cardiac Clearance because not one nurse "knew" there was a cardiac history. Which I figured you'd know because it was mentioned a numerous amount of times. If you didn't looking at a chart, medications or opening your mouth and asking also helps!! Leading to delay in surgery which was not only cancelled but rescheduled and cancelled 3 times the next day to only be cancelled in the end again. Making that 4 times!!!! NP Thelma Diaz with horrible bedside manner. Could not give us and answer on a reschedule besides an " I don't know" who came in rolling her eyes and saying if we had an issue with the reschedule we could call whoever we wanted to complain. Then to top it off we had a surgeon Dr Derrick Cox who is beyond rude and unprofessional for not only never get once showing his face throughout the matter although he was the consulted surgeon on the case but for not once bothering to explain why the surgery was constantly being delayed. He then on a very rude phone call then blamed the Sierra staff for the surgery being delayed because the staff was incompetent! Great way to show that you have a great team if even your surgeon says that about your hospital but still has the decency to trust these nurses with his patients! Me and my family have never had anything bad to say up until now and is very disappointing! Cannot wait to get out of here!!!"
