October 9, 2025I have been with CNC for 4 years. I started weighing 302 lbs, having suffered 26 surgeries and endured 22 years in law enforcement. Needless to say, when... read more I arrived, I was desperate. My health was in bad shape; my mental health was worse. I was looking at additional back surgeries and was gaining additional weight. I met Dr. Lazarus, my first meeting with him he took the time and explained what was happening both physiologically and psychologically. He told me that what was happening wasn't my fault. He guided me through the process, created a plan, first getting me through my next surgeries. Once completed, we created a long-term plan under close observation. It began to work. Weight slowly dropped off, my energy creeped back and the aches and pains I was feeling began subsiding. Ultimately due to my injuries that I had sustained we felt the route of surgery was best and I underwent a gastrectomy (sleeve) that along with Dr. Lazarus and Jamie Shriver, I have lost 105 lbs. and kept 93 lbs. off for 2 years. They work with me every month, they know me, my family and they never forget that I am a human being. They care and they have my TRUST. Please don't suffer any longer. These people can and will help you. Trust them, I am so happy that I did. I know I will have more time with my family because I did. Michael Wagner

After starting with... read more the clinic, I met with Nutritionist, Mary Ellen, weekly and Physician's Assistant, Jamie, monthly. Everyone at the clinic has been wonderful! They are always encouraging at my weekly weigh-ins. Mary Ellen has been such a great inspiring part of my journey! She has given me a lot of good advice and helpful information. I like the fact that the Nutrition Clinic has always been concerned with my overall health as well as my weight lose. The monthly blood draws and body scans helped me a lot, too. Working with the Clinical Nutrition Center has helped me lose over 100 pounds! My weight has been over 300 pounds for the last 6 years! I now weigh about 206 lbs! My goal is to be under 200lbs and maintain that weight. I know the clinic will help me get there and also maintain my weight lose as well!

August 9, 2023I had been to several Denver area weight loss clinics prior to this one and there is just no comparison. Dr. Ethan Lazurus and his entire staff are helpful, kind,... read more knowledgeable and just so easy to work with. They are also very competitive from a pricing perspective, and flexible. I have been going to them off and on for 6+years now and they never make me feel guilty or uncomfortable if I fall of the program, or stop coming regularly. They are always respectful and extremely personable. They always have great recommendations and will share opinions, but are never pushy.

September 8, 2021I called Dr Lazarus in the middle of the pandemic convinced I had an eating disorder at 69!!!!! He quickly had me understanding that my weight gain and binge... read more eating was biochemical, a component of brain chemistry. This was easy for me to understand because I’m a therapist and it’s a major question I ask in assessing depression. Dr Lazarus is personable, caring, kind and not shaming at all. He adjusted medication and with the help of a wonderful nutritionist, MaryEllen, within 6 months I lost 40 pounds with out being hungry. The staff is supportive, kind, and helps you to understand there is much more going on to weight loss than will power. A lot is determined by changing hormones and brain chemistry. If you are struggling with your weight please give Dr Lazarus a call. You will not regret it. My cholesterol is back to normal, my clothes fit, and my self esteem feels so much better that I’m not to blame. What a team!! Plus, he’s an incredible musician.
