Hans J. Schmidt, MD, FACS
“I was fortunate to have the opportunity to pioneer minimally invasive weight-loss surgery in the state of New Jersey. When I saw the weight-loss results that were possible and the potential they had to change people’s lives, I knew I wanted to make bariatric surgery the focus of our practice.
“When we developed our program, we knew it was essential to focus on patient education and aftercare support. We’ve learned that the patients who are most successful for the long term make the decision to have surgery after fully understanding its risks and benefits. Our program is comprehensive, with a lot of emphasis on postoperative nutrition and lifestyle. I believe it is one of the things that has distinguished us within our field.
“Because we have four surgeons on staff, we are able to offer our patients access to medical care 365 days a year. One of us is always available to take a phone call, answer a question or address a concern. Our depth and breadth of experience is another thing our patients really appreciate; they know they are getting the most expert care. And even though we perform a high volume of surgery, we treat each patient with an extraordinary degree of focused, personalized care.”

Amit Trivedi, MD
“I always knew I wanted to be a doctor and began pursuing my training right after high school. As I was completing my surgical residency, laparoscopic surgery was just coming to the forefront. I recognized immediately that it was the wave of the future and that I wanted to be on the leading edge of minimally invasive procedures.
“What I find most rewarding about bariatric surgery is that it allows me to develop lifelong relationships with my patients. Observing the change in a person’s health from this one intervention is amazing – and the change is almost immediate. It impacts one’s health and personality and changes the way a person is perceived. It’s gratifying to be a part of that.
“I think a lot of people are fearful about weight-loss surgery because they have received misinformation. That’s why we focus on educating our prospective patients right from the start. We want them to know that weight-loss surgery is a good and safe option in the hands of the right surgeon.”

Douglas R. Ewing, MD, FACS
“I chose to become a laparoscopic specialist because I knew that minimally invasive surgery was at the forefront of surgical innovation. It’s technically challenging for the surgeon and offers improved results and enhanced recovery time for the patient.
“I enjoy both the intellectual and psychological aspects of my interactions with my weight-loss surgery patients. It’s extremely rewarding to see the gratitude expressed by former patients when we are able to help them literally transform their lives through weight loss. Everything changes for them – their health, their social interactions, often even their career. And they are among the most thankful patients you will find. It’s tremendously gratifying for me as a surgeon to play a part in that transformation.
“My goals are to stay at the forefront of surgery, provide leading-edge training and provide patients with the best and most up-to-date care.”

“In recent years there have been many technological advances in the field of minimally invasive surgery. The challenge is to be able to provide the patients with the most up-to-date care and put their health and well-being at the forefront of our practice.
"I am compelled by the immediate effect that laparoscopic surgery, in particular bariatric surgery, has on a patients quality of life. I appreciate the long term relationship that is built between the doctor and patient and the satisfaction of improving someone's life.
“My goal is to give my patients the care, attention, support and experience they need throughout their journey and always be available; before, during and long after surgery is completed. ”Education & Training
