I 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

I 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.

Dr. Lazarus and his staff, including Susan Ellis, are exceptional. They tailor each program to the individual and you are never made to feel guilty. They do what... read more works for you, not what some program says. I've lost over 50 lbs with them and kept it off for 2 years and I feel great. If it were as easy as just eating less and exercising more, there would not be a trillion dollar industry around weight loss. There is more to it and using all the tools in your tool box should include Dr. Lazarus and his team. I've recommended them to family members, co-workers,teammates, and every single one has had a positive experience.

FAQ
We encourage you to set up a free 30 minute consultation with one of our amazing Registered Dietitians or Physician Associates. We can review our programs, give you a chance to see the clinic and meet the staff, and figure out if this is going to be a good fit.
We are a medical clinic and are happy to provide you a receipt for the services you receive. You are welcome to submit these to your health insurance carrier and request reimbursement; however, many insurers do not cover weight loss treatments. We do not bill insurance directly, and our fees are not artificially inflated for purposes of insurance billing.
If your BMI is 30 or more, or if it is 27 or more with a related medical problem like elevated blood pressure or cholesterol, then the use of weight loss medication is now recommended. There are lots of choices ranging from older inexpensive generic medications to the very expensive injectable GLP-1 medications like Wegovy and Zepbound. Whether or not to use these medications is a complex decision that we individualize with every patient.
Why not click here utilize are tool to determine if you are a good candidate?
Losing weight and keeping it off is far more than eating less or moving more. Decades of experience have shown that keeping weight off is hard because the body fights back. For this reason, we need a very structured approach to eating, physical activity, environmental restructuring, behavior change, and medical weight loss management. Otherwise, before we know it, the lost weight seems to find its way back!
Medical weight loss management is far more than adding weight loss medication. Sometimes there are other medications causing weight gain - removing one of those, or substituting an appropriate different weight-neutral medication can be incredibly helpful! There are often missed diagnoses or mismanaged diagnoses making weight loss challenging - slow metabolism, slow thyroid, sleep apnea, liver or kidney problems, pre-diabetes and the like. Our providers are skilled at looking at the whole picture, not just the weight.
We offer patients evidence-based medical treatments; however, we are not a surgical practice. Most patients considering weight loss surgery are required by insurers to undergo a 6 month medical weight loss program first. We are happy to refer for surgery, and can work with you both before and afterwards.
