I highly recommend Dr. Antanavicius and the entire Abington group. Everybody is knowledgeable and friendly. I had researched the DS thoroughly and had many questions for the nurses and for Dr. G. I loved Dr. G. He was fabulous and has a great bed side manner. His staff is extremely supportive and they have their own experiences and are a great support venue.
My surgery was one year ago - I chose Dr. G on purpose being convinced that he was my right choice- and I was right - surgery went well and I recovered much faster than expected with no complications. A lot has to do with the skill and the unique technical savvy of Dr. G with the Da Vinci robot. Sadly I could not meet Dr. G at my 1 year visit because he was called to an emergency but I hope to meet him in 6 months and thank him in person for my new life and new found health: all my comorbidities are gone and I lost over 100 pounds Thank you Dr. G!

I have found Dr G to have a very good bedside manner - pre and post op. Regardless of what he has to say it always comes out in a warm and kindhearted way and he doesn't rush you. I love love love Dr G!!!!!!!!!! He did a great job with my surgery almost a week ago and everything has been going well so far. I'm very glad I chose him!!!!! I can't really think of anything negative to say about him.

Yesterday was my first visit with Dr. G. and already I liked him more than I did Dr. Bonanni. I never felt like he was rushing me, he thoroughly reviewed my chart with me, spoke to me as though I was an intelligent human being, and happily answered all of my questions.
He was very open about the seriousness of the surgery I am looking to have, emphasizing the important of aftercare to be both successful and healthy. I left feeling as though I were in good hands.

It's been three months since my gastric bypass surgery and nine months since first meeting Dr. Antanavicius and his wonderful staff at Abington Memorial Hospital's Institute for Metabolic and Bariatric Surgery in Warminster, PA. They've all been wonderful, warm, knowledgeable, helpful, professional and skilled -- everything you'd want while undertaking such a new and life-changing decision as this one.
Ultimately, weight loss is such a personal journey but they have helped ease my fears, educate me on my options and the new way of eating and living my life. By the time my surgery date arrived I was confident in my decision to proceed and fully aware of the challenges ahead of me.
The past 12 weeks have flown by and I'm amazed at how easily I've transistioned from one phase of bariatric meals to the next. And, because I followed their guidelines and advice, I'm happy with the results and have had very little side effects post-surgery. BTW: I'm down 66 lbs. since starting this process (46 lbs. since surgery date). I feel more like my true self and I'm healthier and more energetic than I have been in years. My biggest problem now: my clothes are all much too large and I'm not yet ready to invest in "all new" because I'm not finished dropping weight. Tell me that's not a welcome problem to start of a new year?!?!
I'd give Dr. Antanavicius and the entire staff top rating throughout every step of this journey.

Dr. G, as he is called, was very good to deal with. He put you at ease immediately and engendered complete confidence. The staff at this office and in the hospital were all excellent and delightful to deal with. I had my surgery, VSG, in March and it's been very successful. Aftercare is stressed and encouragement is always provided. All risks were discussed - this program and this dr. are very though. I have recommended Dr. G, and or this program to a number of people and think highly of everything related to them.
I really have no negatives to state - this whole experience exceeded my expectations.

My surgeon was Gintaras Antnavicius; he is better know at the center and hospital as Doctor G. He was fantastic; he knows his business, the entire center for excellence is a great group that really care about you. They dot every i and cross every t prior to surgery for your saftey. I would reccomend them to anyone considering bariatric surgery.
