Nick's Story

"I wish I would have come here first. We spend all our time reacting to the next great weight loss tip or program. It might work for a while, but does not last and we end up yo-yoing from one fad to the next – as we gain more weight." Read More

"Dr. Ziltzer and everyone who I have come in contact with at the Scottsdale Weight Loss office have been so encouraging and I look forward to seeing them each week.

You can take it from me that this is a program that produces results. The staff is always positive, supportive, and never judgmental.

Your visits always result in positive reinforcement, no matter if you had a good week or a bad week." Read More

I cannot say enough wonderful things about Dr Robert Ziltzer! He helped me reach my ideal weight and more importantly maintain it for over 2 years. He has also helped me keep my blood pressure exactly where my internist wanted it. Dr Ziltzer is not only exceptional in weight management but also a truly gifted internet’s. His knowledge, kindness, and dedication are remarkable. I am deeply grateful for his care and recommend him whole heartedly!

I really felt comfortable with Kristen at my initial appointment.  Everyone at the center was caring and friendly, from Bianca, at the front desk, to Lily, who is the MA.  Kristen listened to my frustrations and prior disappointments about what has not worked, and is confident that she can help me achieve my goals of weight loss.  I am looking forward and excited to see the success I will attain.

I'd lost 20 pounds on my own and struggled to keep it off.  I decided GLP-1 meds were the next step in losing more and keeping it off.  I wanted a medical doctor supervised program and chose SWLC. I am so very glad I did!  The team in Glendale is so supportive and kind; and when I feel discouraged, they pick me up with positive energy and input.  They really do a great job with encouragement all the time. 6 weeks in I've lost 17 pounds, and am approaching weight loss with a very new perspective.  Also knowing that when I reach my target goal, they'll be there through maintenance and beyond is encouraging as well.  Good to not feel alone on this journey.
