Don't take our word for it. Listen to some of our satisfied patients.


When I came to you I weighed around 330 lb., but as of today (Jan 6, 2011), I weigh 227 lbs. Thanks to you I started eating better, I joined a gym and hired a personal trainer. I feel great and I love my new life! The gym even posted before and after photos of me recently. I am not done losing weight. I would like to lose at least another 27 lbs., but now I have the drive and confidence to do it.

Thank you,



I had been steadily gaining weight for almost a year and was frustrated with the failure of the weight loss methods that had worked for me in the past. Finally, in late January, I had the reason for my metabolic change and resulting weight gain. I was diagnosed with a hyper thyroid and put on Synthroid.

I now knew why I had gained the weight and then decided to have a consultation with Dr. Knopke in February 2008. I gave him my health history, including my newly diagnosed thyroid condition. I asked him if he could help me lose the weight and he said "Yes, definitely". And he did!

After the initial consult, he laid out a program for me that included his meal replacement and exercise plan. With his regular counseling, I worked on my eating habits and most importantly, my grocery shopping habits. I learned how to shop for healthy foods and read labels. I found that I really enjoy eating fresh vegetables and fruits. Eating the right foods was fun and enjoyable. Eating the right things combined with a monitored exercise program worked.

Dr. Knopke helped me reach my goal weight in less than 3 months!

Thank you Dr. Knopke.

2006 Excerpt from Inland Empire Magazine's Top Doctors

"My Father was in Dr. Knopke's care at Riverside Community Hospital during his five week stay in the hospital. If it wasn't for Dr. Knopke's caring and dedication, my father probably wouldn't be here today."

The Obesity Medicine Association is the certifying organization in the field of Bariatric/Obesity Medicine. They are an important source of education and policy making to ensure that medical weight loss is done in a safe and effective manner. Twice each year, they sponsor an educational meeting where national and international experts on medical weight loss and researchers in this field are invited to educate other physicians in this field. The providers at Inland Empire Weight Loss regularly attend these meetings and utilize other educational materials put out by the OMA to stay abreast of the latest techniques used medical weight loss. Inland Empire Weight Loss is the only weight loss clinic in the Inland Empire that is a member who is compliant with the strict guidelines set forth by the Obesity Medicine Associationin order to assure that weight loss is done safely and effectively.

Riverside Community Hospital

Riverside Community Hospital has recently launched a Center for Surgical Weight Loss. Prior to undergoing bariatric surgery, there is often a requirement to undergo an intensive medical weight loss program. Riverside Community Hospital has chosen to work with Inland Empire Weight Loss to provide medically supervised weight loss services on these occasions.

Imagine Plastic Surgery

Imagine Plastic Surgery and Inland Empire Weight Loss have worked closely together since 2008. Some of our weight loss patients who lose a significant amount of weight will develop excess skin on their arms, face, and abdomen. Through our relationship with Imagine Plastic Surgery, we are able to arrange for surgical correction of these problems when they are confronted.

Here are a just a few examples of our success stories.

If you are a success story and you would like to share with others to help them realize their potential, please send us your before and after pictures to:

“TJ” lost 54 pounds*

Weight loss program success

TJ frequented our office as a sales rep. One day at lunch we were talking and he confided in me that he was starting to have medical problems related to his weight. When he went to his doctor, he did not like the advice that he was given. Basically, he was told to start taking medications and wait for the condition to get worse. I offered TJ an option, weight loss. TJ is one of our star patients. Using the techniques taught in our weight loss program, he lost 54 pounds and ran a marathon. I am very happy to report that TJs obesity related health problem resolved and he has taken his life back.

“Dominique” lost 45 pounds*

Weight loss program success

Dominique is a member of our staff. When we hired her into the office, she started to see how other patients in the office were losing weight and she decided that she wanted to give it a try. Working closely with our health professionals, Dominque worked through the program and the you can see the wonderful results. If you start our weight loss program, you can always ask Dominique how she did it.

“Stephen” lost over 200 pounds*

Weight loss program success

Stephen is one of our biggest success stories, quite literally. When he came to us, he was in bad shape. We were treating Stephen for many common weight related conditions. One day I said to Stephen, you do not have to keep doing this, I can help you. At the time, he had trouble getting into his car. He told me that in order to get into his car he had to tie a rope around his left ankle and pull it into the car. At his heaviest he was 464 pounds. When he came into our office, he would come in using a wheel chair. As he started the program, we celebrated each of his succussful milestones. When he told me that he no longer needed a rope to get into the car, we celebrated. When he stopped using his wheelchair and graduated to a walker, we celebrated. When he graduated from a walker to a cane, we celebrated. And when he walked in and out of the office on his own, we celebrated. Stephen eventually lost 264 pounds. Stephen continues to work the program and he continues to walk into the office on his own. Congratulations Stephen.
