DR Ahmad is by far the best I have encountered. When dealing with weight loss surgeries. I’m recommending his office to everyone I talk to about the procedure I had ( gastric sleeve). – Jerry R.

I had a great experience with Dr Ahmads group of doctors, office staff and my experience with the procedure. – William B.

I absolutely LOVE Dr Ahmad!! I can’t say enough good things about him and his team. They were professional and kind from the word GO. They made me more educated and at ease with each visit. They honestly made me feel they were taking the journey with me. My surgery went great, they made me feel like a princess during my hospital stay. And they’re still with me after my surgery, which I didn’t realize was when I would need them most.

If you’re considering bariatric surgery, you won’t do better than Dr Ahmad and his team. – Carolynn R.

From the moment you start your process, you feel that they actually care about your well being. The staff does everything possible to make sure that you have single thing you need to proceed with your decision and life changing decision. The doctors awesome of the most knowledgeable when it comes to any questions you will have, and support you every step of the way. The pre and post care that is given is wonderful, with the most polite staff you will ever meet. Your results will absolutely be felt and seen, by the person most important, and that’s YOU! I promise that. it’s worth it. – Terri B.

There really aren’t enough good things I could say about Dr. Ahmad and his team. Due to my insurance I had a 6 month mandatory wait before my surgery. Dr. Ahmad and his team were on point for every appointment. I finally had my surgery last Wednesday and I couldn’t have been happier! From making me feel comfortable during pre op, to the actual surgery and then his nurses, cnas and post op medical team- AMAZING! You really can’t do any better than Dr. Ahmad and his team. I drove all the way from Wantagh to Port Jeff just to get my surgery and be treated by him, and I don’t have any regrets. Thank you Dr. Ahmad + staff!! – Jocelyn R.

I had a great experience from the very beginning. Everyone in the practice is nice, helpful and explained everything in detail. I was nervous at first but they put my mind at ease. It was a very smooth process for me. I had hardly no pain and recovered quickly. Dr. Ahmad has personally worked with me throughout the whole process and has been wonderful. All of the doctors have been great and all there to help – even a few times in the middle of the night!

It was a big decision that I’m so glad I made…I’m very happy with the outcome. I had my surgery a year ago and I’ve lost 75 lbs so far. Here is a picture of my year’s progress…. – Stephanie C.

I had the bypass and a year later I’m down 110 pounds. I highly recommend Dr Ahmad and his team. If you want to lose weight once and for all do this. – Gerry S.

Fantastic. From beginning to “end” (though this is totally ongoing), Dr Ahmad and his staff have been the most knowledgeable, understanding, and determined to make me successful! I already recommend the practice to anyone inquiring about my bariatric surgery. They truly do their best to make sure each individual is healthy enough to undergo surgery, they check every possible indicator and go above and beyond. Thank you so much! – Jenny D.

My experience has been first rate from my first seminar visit and is still fantastic 4 months out of surgery. Down about 120 lbs since first visit. Feeling great. Thank you very much for my new life. Thank you also to the entire office staff for all there help. – Neil D.

I went to Dr. Ahmad because he was rated the best; after experiencing my procedure, I had the sleeve gastrectomy, I can see why he is rated so high. Dr. Ahmad takes a hands on approach toward his practice; he personally scrubs in on every procedure, and unlike a lot of condescending doctors he was always at my disposal for any questions that I had. His staff is second to none; every one is very courteous and attentive especially Dr. Ahmad’s wife who would always put me at ease in the midst of any concerns that I had. I am two weeks post op, and 21 lbs. lighter. My journey toward a healthier lifestyle has begun thanks to Dr. Ahmad and his staff. – Bill D.

Hello, my hospital stay was fantastic, the staff did an excellent job in caring for me. I had difficulties with the stage 1 diet, the food gave me gas. Stage 2 is not much better, the protein shakes taste like evaporated milk and is making me feel like throwing up. I am hungry and I want to eat chewable food like grilled chicken and burgers. I know I need drink the shakes but it is difficult. – Sherry B.

Dr. Ahmad and his office are very professional and treat their patients with care and respect. Scheduling appointments is very easy and all staff are eager to help. They guide you through your experience with skill and ease. The nursing staff on the Bariatric Step Down Unit is unparalleled in kindness and expertise! Thank you so much. – Susan M.

I was very happy with the treatment Dr Ahmad gave me. I had the gastric bypass surgery done on 4-30-14 and there were no complications. Dr Ahmad was very open to the multitude of questions that my wife had all the way up to my surgery. She was very nervous and he went out of his way to make her feel better. He then made it a point to assure her while I was in recovery by both calling and when she was still nervous came down and talked to her. I would recommend Dr Ahmad to anyone wishing to get the bypass or sleeve. – Curtis D.

From the moment I made the decision to have the surgery I knew I wanted the best. My expierience was a good one. I would have liked a little more from the dietary personal. Recipes are crucial to a successful weight loss. Canned cream soup yuk. So I made my own. You need more than 2 pages of guidelines. I learned a lot. The staff is an asset. – Darleen G.

Dr. Ahmad and Dr. Agarwala repaired my complicated hernia. I cannot say enough about how wonderful the whole experience was for me. Their compassion and the level of unmatched expertise was above and beyond anything I could of have asked for. From beginning to end I was well informed of exactly what was going to be done during the surgery and during my recovery. I would highly recommend Dr. Ahmad and Dr. Agarwala as they brought great comfort and kept my family informed every step of the way. – Imran A.

Dr. Arif Ahmad and his team changed my life and brought me back to the person I was 20 years ago. While I was always a happy, confident women, as I got older the weight just continued to slowly creep up even though I ate fairly healthy and exercised regularly. If you are considering weight loss surgery, I highly recommend Dr. Ahmad and his team 100% professional and supportive. – Linda G.

Great surgeon. Very thorough. Very knowledgeable – Chris C.

My Name is Ted and I am writing a review under my sons screen name. I have a lap band since June 2007. The journey is difficult loosing over 100 lbs. The office staff, hospital, Linda from nutrition have all educated me the patient to become a success. It is difficult to take the 1st step,but Dr. Ahmads staff are there for you the Patient to succeed.

They also have a wonderful support system. It is hard work to both loose and to maintain the weight loss. I wish I had the nerve to get it done sooner. Now I have learned to enjoy what I eat. Many thanks to all.- Peter G.

Dri. Ahmad saved my life. Best decision I’ve made in my life. Every single health marker for me has improved. Blood Pressure, heart rate… everything. If you’ve made it this far, If you’ve even taken the step to read this. Keep walking. Follow up and do it. I had the Gastric Sleeve. I can eat anything, just not everything. I have real meals every day.

Just do it. He’s the best at this in the area hands down. Stop waiting…your real happy life is on the other side of your fear.

Thank you Dr. Ahman, Sima and the staff. – Heywood O.

I had a great experience with Dr. Ahmad, his staff, and my procedure. They are careful and cautious, but also caring. I wish I had done this year’s ago!! – Lesli F.

I had the gastric sleeve a week ago today and I couldn’t be more thankful! While I was not prepared for the amount of pain I’d be in for a few short days after surgery, the results thus far have been SO worth it! It will require a huge life change, which some people must prepare for better than I think I did, but again, worth it! It has only been a week, and I have dropped around 25lbs. I had tried time and time again to do this on my own but suffice to say, couldn’t. I had/have PCOS which makes it all the more difficult to lose weight on my own. This TOOL helped me put my body into my control again. Because of the PCOS I hadn’t gotten my period in over a year, and I got it for the first time 2 days ago! I guess it’s my body’s way of saying “I’m back in business”! Thank you Dr. Ahmad & Dr. Agarwala. Thank you thank you thank you – Elana G.

Dr Ahmad,s Staff, (hospital, office,Linda from Nutrition, Annmarie all are a wonderful team! Dr. Ahmad doesn’t threaten anyone At all . I had my band installed 6/2008 and lost over 100 lbs, and kept the weight off. I have learnd to eat healthy and to enjoy what I eat. Yes, I had a difficult Journey proir to the weight loss surgery by having 27 tia strokes, and emergency gall bladder surgery the year before The lap band. I have nothing but positive things to say . Dr. Ahmad and all the staff are caring peolple that also decided to improve there lifestyles. They work for you the Patient and assist you with everything for you and you family. Others share that in support.

Yes my journey is tough, but in order to succeed you must make peace within your own being and both listen to what is being said to you, and most of all you must apply the effort to succeed. I am so grateful for the bedside manner that made me feel like a king during the hospital stay. All the foolowup visits after the operation is just as important to all. If anyone wrote a bad review it is there own fault by not listening and or be willing to apply the effort. I just wish I had the courage to have the operation sooner! – Theodore G.

Today is my one year anniversary of having by-pass surgery it was the best decision I ever made. I had tried in the past with other Providers but none made me feel at ease and able to trust. Dr. Ahmad and his team are fantastic, they are always there for their patients. Their support groups are amazing, and the support they give us on a daily basis is unheard of by those I know who had this procedure done other places. Thank you Dr. Ahmad for saving my life this morning my scale said 115lb, one year ago it said 210lbs to be able to look at myself in the mirror and love who I see I owe it all to you and your team. – Kathy F.

Amazing!! I can’t say enough great things about this office. The doctors and staff are wonderful and I’m so happy I chose them for my bypass. No complications at all, everything went totally smooth and I received the best post op care. I highly recommend. – Jeanine F.

Dr Ahmad and his staff are the greatest. I can not thank them enough for everything they do. If I could add more star to rate them I would , they all go above and beyond for all their patents, thank you, thank you – Mary L.

I have had a great experience this far! I am now 3 weeks post-op…

Great Doctor – Michael C.

After attending a seminar and listening to Dr. Ahmad, I decided to have a gastric bypass. For the first time, I heard someone tell me that at this stage, it was indeed impossible for me to loose weight through diet, and that I needed an intervention. I could stop feeling like a failure, and do something that could and would work. I did my homework and knew that Dr. Ahamad was the best in this field; he even convinced my oldest daughter, and let me tell you, that is quite a feat. I am very afraid of anything surgical, and I had more that my share of anxiety. But the kindness of Drs Ahamad and Argawala and the entire staff helped me through. I had the surgery 1 month ago today, and after weighing myself yesterday, I did a little dance around my house. I have lost 25 lbs in 4 weeks *, and I have not been hungry at all. I have followed the diet, followed the rules, and I have had no problems, it has been absolutely great. Any discomfort in the beginning was so worth it. I definitely would have had a short life if I stayed obese and the list of life-threatening diseases would have gotten longer; now, I feel reborn. I look forward to my new life. The best is yet to come. My daughters are thrilled and amazed at my progress. and NEVER NEVER would I have done this if I had not met Dr. Ahmad and his team. To his wife who visited me in the hospital and to the wonderful staff on the bariatric hospital floor, to Lisa in Nutrition, thank you a million times. – Odette L – review

My experience with Dr. Ahmad was that he was caring and interested in my personal goals both before & after surgery. The entire experience with the gastric by-pass proved to be exceptionally beyond my expectations. I lost 100lbs * , no longer needed any medications for the various medical * issues & I am healthier then I have ever been. I highly recommend Dr. Ahmad and his team for bariatric surgery He is the best in this field!! – Diane S.P – review

March 20,2013 was the first day of the rest of my life began as a newer me. Thanks to Dr. Ahmad and his staff I have now lost 105 lbs 7 months * . Looking at the pictures of me before surgery were really surprising to me I knew I was heavy at 300 lbs but I never thought I looked the part. As the saying goes pictures don’t lie and wow I’m really shocked looking at the differences so far. If you’re on the fence about the surgery “get off and do it” the procedure was uneventful and the new style of living is grand. – Charles W.

Dr. Ahmad has changed my life. I had been to 3 seminars including Dr. Ahmads. After each seminar I consulted with the surgeon from the seminar. I never really felt ready to go ahead and say yes to the surgery until i met with Dr. AhmadAnd his wife. The staff is great. Knowledgeable, friendly, professional, understanding and just amazing. All of them. I battled obesity all my life wnd started my first diet in 6th grade. Since meeting with Dr. Ahamd from my first consult to the actual surgery date of 8/30/12, I have lost 90 pounds * and went from a size 26/28 to a size 12 * . amazing. He has such a passion and love for what he does and for his patients. He is an amazing Surgeon and human being. A wonderful staff and support system are available anytime. The stay at Mather Hospital was wonderful too. The staff is incredible there. Thank you to Dr. Ahmad and his wife for everything. I could write a book on all the possitive I have to say about them and their staff. I love you guys. Thanks for making A dream come true at 46 I feel and look better than ever! – Dawn P. – review

Five years ago I was blessed with the option to have lap band surgery! 167 pounds lost * and I wouldn’t change it for anything feeling great! To an amazing doctor and staff you are all one of a kind! – Kim D.

While driving in the car today Jake and I had a great conversation…Jake – “Daddy I saw an old picture of you on dad’s phone and your arm was really big” Me – “Just my arm Jake?” Jake – “no all of you, you were fat” Me – “I was, so what am I now Jake?” Jake – “you are skinny” Me – “is that how you see me now?” Jake – Yes!” That’s because you ate too much right Daddy? Me – “yes Jake you are right, Do you remember Daddy being that fat?” Jake – “no I don’t ” Jake – “so all that had to do is put 5 holes in you and let out all the air out and now you are skinny?” Me – “Yes Jake it was just that easy” (I wish it was)…out of the mouths of babes. Right after my surgery my doctor told me “Isn’t it great that your kids will only remember you as being skinny? I didn’t believe my doctor at that time, but I guess I was wrong. I love my “Little Men” and today they made it perfectly clear to me that I did the right thing. Thank you doc! I was born in Mather Hospital twice…The first time on October 26, 1967 and then once again on June 04, 2012. I love myself and even more I love my family. – John C. *

Dr. Ahmad has changed my life in an amazing way. I had gastric bypass 6/7/2011 and have lost 125 lbs. in 18 months * . With the weight loss i found a 10 cm benign tumor in my breast and had a mascectomy and now I’m perfectly healthy.
