3 out of 5 stars Orbera Intragastric Balloon

Mixed to Negative Experience

I had a very mixed to negative experience with Dr. Rosen and his nutritionist Megan on my Orbera balloon journey. Dr. Rosen is very friendly and knowledgable, he makes you feel comfortable, but not necessarily prepared for post-procedure. He definitely talked up Megan before I met with her, and stressed that I would have her for a full year, however when I actually met with Megan, I felt the...

My Only Regret is That I Didn't Have my Surgery Sooner! - Manhattan, NY

Dr. Rosen is absolutely amazing! From the first day I met him until a little over a year after my procedure my opinion of him remains the same. He is patient, kind, consummate professional, determined, knowledgeable and cares about his patient. I describe him as determined due to the fact that the insurance company denied me over four times and Dr. Rosen and his staff never gave up on me. He demanded a conference call with the all the top people who were making the decision and treated me as if I was his ONLY focus while going through the entire insurance process. You never feel rushed when you're being seen by him. He answers all your questions. I remember laying on the surgical table and having him come over and rubbing my forehead until I feel asleep. I have never had a Doctor who allowed me to text him if I had a problem. His passion isn't driven by money or fame, he's just decent human being who happens to be a brilliant surgeon trying to combat obesity one patient at a time! He gave me the skills to be successful in my weight loss, he gave me my confidence back and this didn't just end after my procedure. The after care/follow up is amazing! His whole team which consist of his office staff, the greatest Nutritionist in the world...Meagan and the most amazing Social Worker in the world...Carol who we would have group meeting with to discuss our feelings and to be reminded that we are not alone in our journey. Take my humble advice, give his office a call and make an appointment to see him for a consultation, you won't regret it!
