Keith Kreitz, M.D., F.A.C.S.

Earlier this year, we welcomed Dr. Kreitz to Inspira Health as our new medical director of Bariatric Services at Inspira Medical Center Mullica Hill.

His philosophy of care?

“I always give enough time to every patient based on what they need,” explains Dr. Kreitz in his physician profile. “I would rather sit down and spend more time drilling down to what the patient needs, not worrying about the clock and what else is going on, until we get done what we need to do together.”

Dr. Kreitz specializes in laparoscopic gastric banding, laparoscopic Roux-en-Y gastric banding, laparoscopic sleeve gastrectomy, surgical endoscopy, endoscopic gastric balloon placement, and revisional surgery.

Most recently, Dr. Kreitz served as director of bariatric surgery at St. Mary Medical Center in Langhorne. Kreitz is board certified by the American Board of Surgery and serves as a member of the American Society for Metabolic and Bariatric Surgery. He has also served as assistant clinical professor of surgery at both Louisiana State University and the University of Pennsylvania.

Nauveed Iqbal M.D.

Dr. Iqbal is a general, bariatric, and vascular surgeon at Inspira medical centers in Vineland and Elmer. He is double board certified in general and vascular surgery by the American Board of Surgery. Dr. Iqbal specializes in treating vascular and endovascular conditions and performs procedures such as gastric sleeve and lap band surgeries. 

Ahmed Attia, D.O.

Dr. Attia attended the University of Alexandria in Egypt where he earned his doctorate of Medicine. He also attended the College of Osteopathic Medicine in Old Westbury, New York. Dr. Attia is certified in laparoscopic surgery and finished his bariatric fellowship at Community General Osteopathic Hospital in Harrisburg, PA. 

Derek A. Stephenson, M.D.

Dr. Stephenson received his medical degree from Morehouse School of Medicine in Atlanta, GA and completed his general surgery training at the University of Arizona Medical Center. Dr. Stephenson completed a bariatric surgery fellowship at Orlando Regional Medical Center.

Nationally Recognized Center of Excellence

Horizon Blue Cross Blue Shield of New Jersey has recognized Inspira Medical Center Vineland as a Blue Distinction® Center+ for Bariatric Surgery. Blue Distinction Centers are nationally designated health care facilities that show expertise in delivering improved patient safety and better health outcomes.

At all of our medical centers, our bariatric services team adhere to strict quality guidelines that promote lasting results.

Emphasis on Patient Education and Support

By using a range of educational tools and support systems, Inspira’s bariatric services team keeps patients informed about what they can expect before and after surgery. Undergoing weight loss surgery is only part of the journey and keeping the pounds off can be diffcult if patients don’t understand how to adjust to their new lifestyle. Whether you suffer from a condition such as diabetes or are struggling to find an exercise regimen that works for you, our dedicated team of caregivers is here to guide, support, and inform.
