Dr Ahmad was great from the beginning all the way through the post-op. Had the Gastric Sleeve 5 weeks ago and I feel great and already down 40 pounds! I followed the diet plan and eating advice and I feel great. The office staff from the front desk to the nutrition appts were courteous and friendly. This was a great choice and I wouldn’t change a thing!! Thanks Dr Ahmad and staff!

A Unique Experience

From the start I knew I was dealing with a group of professionals whose mission is to help people improve their lives. In 2005 I was an early lab-band patient, I used another doctor and I was not successful. Skip forward 10 years. While talking to a Nurse Practitioner at Mather she told me one of the best doctors for bariatric surgery was there at Mather. The next evening I attended their information seminar. In the 2 hours I discovered why I had not been successful with the lap band. I learned what my options were and I learned the pros and cons of the procedures. I connected with their point of telling me that the surgery was a tool, and I realized that I had to learn how to use the tool before the surgery. My first appointment was awesome. Dr. Ahmad’s wife talked with me about me needs and desires, who explained the alternatives. I was then seen be Dr. Ahmad who removed 3 cc of fluid from the lap band I thought was empty. I quickly arranged my next series of visits. I appreciate Dr. Ahmad’s staff, as I’ve begun this life changing process I been greeted with friendly manners and an overwhelming amount of information. I’ve never not understood what was happening next. Besides Dr. Ahmad and his associates I want to give a separate shout out to my Nutritionist Lisa, she listened. From her listening we were able to create doable steps and I’ve eased in the process. So here I am, 6 days post surgery, and feeling great. I’ve lost more than 40 lbs, since beginning my retraining in September. I look forward to not only improving my health, but learning how to protect myself by eating correctly. Thanks to Dr. Ahmad and his team, I’m on my way.

The staff and doctors at Dr. Ahmad’s office were professional but also listened and cared about my concerns and always were available to answer questions. My stay at the hospital under the circumstances was made pleasant by the most compassionate nurses, always catering to whatever I needed. They were the nicest sweetest women. They made my stay so much easier. My thanks to all who were involved in my journey. Now it is up to me to continue to a better healthier life.
