Dr. Ren Yu Zhang, MD

I received a call from the Dr's office saying the Dr has reviewed my file and will take my case. My appointment was 1 month later. After waiting over an hour, he came in. After a minute, he received a call and left the room. After he returned, he began to tell me he couldn't help me. Then he received a call and left again. That's twice in a very short period of time. I don't believe the doctor was mentally present. I also think this doctor knew from the beginning that he couldn't help me and only saw me to bill the insurance. I find all these 5 star reviews suspicious because he left the room 2 times during my appointment, making me feel like I was of no priority to him except to bill my insurance. If he knows he lacks the ability and experience to help me, then why have his people call me saying he will take my case?

I was referred to Dr. Zhang who performed by 5 year colonoscopy. He is very professional, personable, patient and knowledgeable. He made me feel very comfortable and at ease at my initial doctor appointments and when he performed my surgery which went very smoothly. I highly recommend him.

I was referred to Dr Zhang with a very painful condition, he was very understanding of my fears and my problem, He takes time to comfortably talk with me during each visit. Dr Zhang went over everything kindly and patiently. I after the very first visit felt very comfortable with him. He treated my health issue and I have relief, I'm thankful that I found Dr Zhang.

Thank you from the bottom of my heart Dr. Ren Yu Zhang! Your passion and love for proctology is absolutely miraculous! I’m so very pleased with your work and extremely grateful for you. After 2+ years of dealing with the fistula I can finally say this chapter of my life may be behind me, God willing. Thank you for your dedication to the craft. It’s not often you find a doctor that truly cares for his patients. You were there for me every step of the way and I will continue to be an advocate for your profession and this disease. I absolutely recommend Dr. Ren Yu Zhang. He’s the best in the state of Nevada and maybe the country.

Dr Zhang is a remarkable surgeon he removed a section of my intestine robotically he came to the hospital every day to see me & provided me and my wife with his personal cell number if we had any questions or concerns after 3 nights in the hospital I was sent home with very little discomfort and was able to eat a high protein diet of regular food to help with my healing he is an amazing Doctor we are very grateful to him and would recommend him to anyone who is in need of a specialized intestinal surgeon Thank You Dr Zhang The Becks

Dr Zhang is absolutely incredible and I feel very fortunate and grateful to have been referred to him for an oversize polyp. He was very open and friendly during the initial visit where he unhurriedly took the time to get to know me and explain options. Being uncomfortable with idea of surgery, he suggested an initial non-surgical approach then provided a direct number to call him if I had any additional concerns or questions. He took his time during the procedure (almost an hour) and skillfully removed the polyp eliminating any need for surgery. I would not hesitate for a moment in recommending Dr Zhang to anyone needing his specialty. He is a fantastic doctor and surgeon who is not only very skilled and knowledgeable but exhibits a warm, friendly demeanor and who truly cares about his patients

Dr. Zhang is an amazing person and Doctor. I have seem my share of Dr.'s and he is at the top of the list.

Once you get pass the front office you find the gem, Dr. Zhang. Direct yet approachable, tells you not what you want to hear but what you need to hear, but all with kindness. He is truly a magician.

Dr Zhang and the Staff are great,friendly, professional and go the extra mile. During my time with him dealing with colon isdue, I lost my Primary Dr. And he and staff helped me in any way they could till I could find a new primary. And Dr Zhang always took the time to listen to me and answer questions. His staff always friendky and quick to help. I had a 100% great patient experience. Thank you!

Dr Zhang is highly skilled and also very personable. He takes so much time with us patients and cares very much for our health. I am so grateful to have been his patient during a very scary time. He did an excellent job on my surgery and has been very caring in all follow-ups.

Dr. Ren Zhang is an OUTSTANDING colorectal surgeon! As a fellow physician I can state that he is highly regarded...and he was terrific for the complete evaluation and treatment of my own + Fecal Occult Blood Colon-Cancer screening test, followed by my + Colo-guard advanced screen. I am particularly high-risk for intestinal perforation due to prior surgeries and he just did a phenomenal job at my high-risk colonoscopy last week which yielded three polyps with absolutely no adverse effects at all--not even any pain or cramping. Moreover, he took the time to make a personal call to review my pathology results--which were benign. Surgeons often have a reputation for being rather cold and aloof, but Dr. Zhang is not only highly professional and knowledgeable--he is genuinely concerned and kind. I Highly Recommended him to everyone. Garry R. Lee, MD

I want to thank Dr Zhang and his staff for the absolute amazing treatment they gave to my Mother during her surgery. This was a nerve-wracking moment for her and all of us and even though we couldnt visit her after the surgery during recovery due to COVID he treated her so good that she couldnt stop complimenting him and his staff which made all of us feel better. The surgery was a huge success and because the way Dr Zhang treats his patients he needs to be commended. From my Mother, my family and myself we all say thank you. God bless.

Dr. Zhang is an excellent doctor and great person.

Compassionate great doctor! Saved my life.

There are not enough doctors like Dr. Zhang, and words cannot express how wonderful, knowledgeable and attentive he is, as well as his team! He goes above and beyond to explain your health predicament; how he will treat it, and to ease your worries. His bedside manner is equal to none! He gives out his personal cell phone number so you can check in with concerns. He gets back to you either immediately or within 1-2 hours. After my surgery, he showed up everyday at the hospital with a big smile on his face, always concerned that I was feeling comfortable and being treated properly by hospital staff; and always eased my concerns. Dr. Zhang truly is an ANGEL walking this Earth! He REALLY listens, remembers you as a person and shows genuine care and compassion. He is truthful and lays out all the risks. More doctors should take note of what he’s doing-his empathy and follow suit! Thank you Dr. Zhang for being so INCREDIBLE, KNOWLEDGE, SKILLED, CARING, and COMPASSIONATE!

Excellent surgeon with a tremendous level of caring and compassion also.

He is the best Dr Very Kind, Understanding, Good listener Thank you Dr Zhang for everything

Dr.Zhang knows how to get through to any patient by seeing their interest and using that to explain the situation. He performed a sigmoid Cancer resection on me and saved my life. I highly recommend Dr. Zhang for his caring and professional attitude towards his patients.

Excellent Doctor, exceptional bedside manner. The office staff is so friendly and competent also.

Dr. Zhang has the best bedside manner of any doctor I've met in Las Vegas. He is incredibly knowledgeable and patient in his explanation of medicine to the client.
