My dad underwent a very stressful colonoscopy after his primary care physician found a positive result on his bloodwork. Helen went above and beyond to get him in as soon as possible despite their busy schedule. As soon as Dr. Sach reviewed the results and determined it was a false positive, he immediately let us know. By coincidence, I happened to be on the phone and heard the entire conversation with my parents. As a healthcare provider myself, I was truly impressed by Dr. Sach's professionalism, compassion, and bedside manner. My mom and dad have not stopped talking about how wonderful the entire experience was. I highly, highly recommend Dr. Sach and his office. Thank you for taking such great care of my family.

I agree with what has been said here that Dr. Naim is thorough, knowledgeable and kind. But there…read moreis a lot more to him than just that. I met him in Northridge hospital ER exactly a year ago when he took care of my elderly mother, admitted with a recurrent upper GI hemorrhage. She had been scoped before, and no source of bleeding had been identified. We had almost lost hope in obtaining a valid diagnosis let alone stopping the bleeding. Providers had given up on my suffering mother and were treating her like a hypochondriac... Then came that young yet fearless Dr. Naim. He acted like the person in charge. He is not someone who will accept missing a diagnosis, and this is a trait so rare nowadays. He studied my mother's extensive imaging history. He also called me and explained elaborately his assessment and plan to me. He is a natural teacher. He scoped my mother and found a 3-mm gastric ulcer that he clipped, and we never saw a trace of that again. So thankful for Dr. Naim's care of my mother who soon later passed away for an unrelated reason. Physicians need to remember that how they treat a patient may be the last act of mercy or battery in the patient's life, and one of the last memories the patient's survivors are left with. God bless your hands Dr. Naim.

I was told to see her and schedule a medical procedure involving surgery. I was not provided other options. I scheduled to meet her. She was extremely brief and direct, but kindly. I liked her in the brief time I met her. I scheduled the procedure many months in advance and never spoke with her again. The week prior I did her prep protocol. I am aware that people can feel ill prior but I was so violently ill for 3 days with her prep care medicine that I was up all night sick and unable to function. It impacted my family as I was incredibly ill. Faint, hot/ cold, throwing up, sick in a car. The only times I have ever been that sick are when 1) I was in the ER with my appendicitis and 2) directly after a six hour surgery due to anesthesia. Also once in Paris after having shellfish but that passed in 5-6 hours, this went on for days. I let the office know multiple times and asked if she could please talk with me. I spoke with reception and an assistant, no nurse and no doctor. They reduced the medicine and I started to feel better. I spoke with a family member who is a hospitalist out of state and he was really concerned. I asked about other options and was told there are some, not as solid, but less likely to make me sick and suggested I speak with the doctor. I called the office to discuss but was shut down. Given the effect of the medication, I was also hesitant to go under without talking with her. I canceled the surgery as I really believe in patient care and that the cure should not be worse than the issue. She then sent me a letter I was fired as a patient, certified mail, due to a break down of communication. In other words, there was no communication but me, very sick, asking for a phone call. How could she take the time to arrange that but not call me back when I was incredibly ill from her prep? I believe I am fairly low risk, so having that conversation would have been much appreciated as well. Yet, impressively, she chose to fire me as a patient due to what, why, I wanted to speak with the doctor who prescribed me medication that made me sick? As if I was trying to run back to her after I canceled my surgery? All I wanted was a phone call at the beginning. I do know how busy doctors are and that trivial matters can weigh them down, but I was incredibly sick. The ability to be humble and kind is what makes this world a good place, and had she taken a moment to discuss options I probably would have just moved forward. I still do not have any questions answered. I dislike leaving bad reviews in the health care space, but there is a lot of arrogance and sometimes it is important - she found it necessary to treat me abusively and so there it is. I am not a lab rat and certainly not going to allow someone to perform surgery on me that is so callous they won't take a minute out of their day to speak with me and assuage the issue they created. Patients do need to advocate for their care, we are human and not everything is suited to everyone.

Background: My primary referred me at 58 years old for my first colonoscopy as standard preventative care. I have no history of cancer, polyps or anything of the sort and am in excellent health so the procedure is 100% covered. Dr Chitayat is in network for my insurance and it was my first visit to his office. The visit was mandatory to draw blood and consult prior to a colonoscopy (in other words, you can't just schedule a colonoscopy. You must visit the doctor first). The office visit was routine, all was fine and the colonoscopy scheduled with the nearby surgery center. ALL of this is 100% covered by Blue Cross/Blue Shield if everything is in network as it was. A week prior to the surgery, the center called to say I would owe $900 when I arrived. I said that was incorrect and explained it was my first colonoscopy and everyone was in network. The surgery center said that Dr Chitayat's office coded it as a colonoscopy based on "previous polyp history" and therefore it was not 100% covered as preventative care. After my explanation that I had never ever had a colonoscopy or previous polyp history, the surgery center had to call Dr Chitayat's office and have them resubmit the proper code for insurance. Dr Chitayat's office corrected it and I was not forced to erroneously pay $900 on day of surgery. To maker matters worse, Dr Chitayat's office INCORRECTLY coded the pre-surgery mandated office visit when submitting the claim to Blue Cross/Blue Shield, thus I received a bill for the office consultation as well. Again, this was WRONG because the visit was 100% covered (corroborated by Blue Cross multiple times) since it was my first colonoscopy and the Dr was in network. Since the Dr's office sent a particular code (the WRONG one), I was being told by Dr Chitayat's office that I was on the hook for the difference. My wife and I attempted to contact the office billing person for WEEKS and left multiple messages requesting a return call. They do not return phone calls at all. We finally went into the Dr's office and spoke directly with the office manager and explained that their billing person would not return messages and we were not going to pay a bill that was incorrectly submitted by them. The office manager referenced the billing person "being young and new" which, quite frankly, is irrelevant and reflective of a poorly managed practice. The office clearly has issues with their billing and in filing accurate claims. Our insurance has been quite helpful but said they can not change a submitted code and the Dr's office must do so and resubmit the corrected claim. Despite Dr Chitayat seeming to be a fine doctor (there were no issues with the actual procedure), I strongly recommend avoiding this practice unless you want never handling hassles due to their subpar billing procedures.
