    “Go the extra mile, it’s never crowded," someone once said. Clearly Dr. Fiez & Dr. Rim do exactly just that! From the beginning to my ongoing weight loss journey their office has gone beyond my expectations. The treatment and care I received added something . Which cannot be bought or measured with money, and that is sincerity and integrity.”

  • Briana

    “Where do I even begin with how amazing this team of people is! After a lifetime of always being the bigger girl and trying every different "diet" option I was ready for a permanent change. When I was debating which procedure would be ideal for me, Dr. Feiz and Dr. Rim were there to really explain and help me choose which option would provide me with the most success.  Dr. Feiz and Dr. Rim are the absolute best! Their team treated me with the utmost respect, patience and kindness. The personal relationship that we have developed over the course of my journey truly shows how they treat their patients like family. 80 pounds down and I have never felt this amazing and confident! I would 10000% recommend Dr. Feiz and Dr. Rim!!!!”

    “From my consulta to surgery Dr. Rim and Dr. Feiz and their staff were very knowledgeable and helpful. I’m so happy with my results so far. I am 2 weeks post-op and I’m down almost 30 lbs. I made the decision to get weight loss surgery so that I can do more with my kids and now I am starting too. The aftercare is also great. 😊”

Introducing The Cosmetic Sleeve
Our exclusive weight loss procedure, the Cosmetic Sleeve is uniquely crafted for patients who are focused on losing 20 pounds or more. The Cosmetic Sleeve Gastrectomy is well-suited for low-BMI patients who have been turned away from other cosmetic procedures like liposuction and tummy tucks. This procedure is minimally invasive, has rapid recovery times, and is a sustainable solution to long-term weight loss management.
