I had my surgery on November 18th, 2010, as of this date, April 1, 2012 I have lost a total of 150 lbs and maintained that loss. Before surgery I was 300 lbs. had congestive heart failure and sleep apnea. I could not walk anywhere without being out of breath. I was slowly but surely killing myself. Dr. Dyer and his staff gave me my life back. I weigh 150 lbs now. I am walking over a mile 3 times a week. I have energy that I haven't had in years. I no longer have CHF nor sleep apnea. I'm able to work in the yard again. I'm 59 years old and feel better than I did at 45.I have a saying now, "I used to live to eat; now I eat to live". I recommend if you are obese and are having similar problems that I have described this is the way to go. I had the Gastric by-pass and it worked.

I met Dr. Dyer when I attended the information seminar in July 2011. He was patient with my questions during the seminar and each time I met with him. After completing the necessary work for insurance purposes, I was able to schedule my surgical consult in January 2012. Once again, Dr. Dyer took the time to go over the risks and benefits of weight loss surgery. As an analytical person, this was key for me. We were able to schedule my surgery for February 14th, the best Valentine's Day gift I could ever receive. I just went to my one-month follow-up. Thus far, I have lost 21 pounds since the surgery and 41 pounds since beginning this journey last July.

Dr. Dyer and everyone in his office, from the nurses to the dieticians and the exercise physiologist, have been very helpful when I needed answers to questions. While I have had just one little post-op issue (mostly due to my learning about what I can do and what I can't do yet), I was able to talk to the staff and get answers within the hour that helped me adjust what I was doing to ensure future success.

The information given at the surgical consult is overwhelming at first, but the User's Manual is priceless. I have only had one or two questions that were not easily found and understandable in the manual.

All in all, I have no complaints. Dr. Dyer and his staff told me what to expect, what could happen, and were willing to take the time during the one time when something unexpected happened. Dr. Dyer definitely emphasizes the aftercare program, and I love my support group. Knowing that Dr. Dyer and his staff, as well as those in my support group, are available when I have questions or when I struggle is what will get me through this process.

Dr Dyer was great. Dr Dyers staff was very supportive throughout the entire preparation for my RNY Gastric Bypass. My surgery was 12/12/2011, took 4 hours. I was an inpatient at Centennial Medical Center. Everyone from Anesthesiologist to nurse were outstanding. I am a month out and have lost 43 lbs post-surgery.

Very happy with my surgery from Dr Dyer. HE is an excellent doctor and took extremely good care of me. My only problem after surgery was nausea and vomiting the first 24 hours. This was not Dr Dyers fault and he took wonderful care of me every step of the way. I am a Registered nurse and I live several hours away. I was very impressed by Dr Dyer when hearing him speak and meeting him in person. A previous review said that he was very calm under pressure and was able to handle any complication that might come up. I did not have any complications ( except the n/v) but I felt like he had my best interests at heart every step of the way I had a sleeve gastrectomy in March 2011.I am down 62 pounds so far. I must also say that Joanna and Robin were awesome every step of the way. I always felt I could take my time...ask Dr Dyer anything and he made a point to make every patient feel cared for...and that he has given a very complete understanding of what the procedure would be. I told him my greatest criteria ( besides being an excellent surgeon) was that he have compassion and I believe that he does have that for each and every patient. I am so glad I found Centennial and had Dr Dyer as my surgeon.

I had gastric bypass almost one year ago and Dr. Dyer was my physician of choice. I didn't know anything about him prior to the surgery but after reading his biography I choose him because of his acknowlegement of Jesus Christ. My faith is one of the most important facets of my life and it gave me comfort in knowing my doctor and I shared the same faith. Dr. Dyer is a true professional and I was impressed with him from our first meeting. He took his time going over all the details of bariatric surgery and answered any questions I had with patience and care. I never felt rushed during the intital meeting or in any of my followup visits. He is what I would call conservative in his care which is fine with me because I know he has my best interest at heart. I had a slight setback a few days after my surgery and he went to great lengths to take precautions to make sure I received the best care possible. I even tried to bargain with him and he never budged for a minute (I guess that makes him stubborn too which is the only negative I can come up with. LOL!) The office staff is exceptional, as well. It is obvious that the patience and care that Dr. Dyer exhibits trickles down through his staff. While I understand 5 star ratings can be questionable because we all have some area we can work on, I cannot honestly rate Dr. Dyer and his staff any lower than that due to the exceptional care I feel they have provided to me. I am truly going to be sad not to be able to go visit with them every 3 months once I reach my one year mark. By the way, I reached my goal weight at my 9 month visit and I'm so glad I decided to take this journey. Centennial provides you with great opportunities for aftercare so take full advantage of this to ensure a lifetime of good health and continued success after your surgery. Did I mention that Dr. Dyer has become my new favorite doctor?

My name is Jenny and I chose to have gastric sleeve surgery performed by Dr. David Dyer. As a kind gental surgeon, Dr. Dyer keeps your best intrest in mind. He gives his patients all the information needed to make an informed decision on which surgery is best for them and their lifestyle. Dr. Dyer gladly answered all questions and concerns. He guides his patients along the process to better health. I would highly recommend Dr. David Dyer. He is a true asset to Centennial Center Treatment for Obesity. I am sure you will be happy with Dr. Dyer as I still am. Thanks, Jenny

Dr. Dyer has given me my life back! I have tried many times to loss weight and been unsuccessful. However, thanks to Dr. Dyer and the ladies in his office I am becoming more successful everyday. When I first meet Dr. Dyer, he made me feel good about the decision I had made. He walked me through the process and explained what would happen. He was easy to talk to and answered all my questions. While I was in the hospital, he came to see me daily and answered all the question I had. He even made me stay in the hospital extra days to make sure I was 100% ready to go home.He made me feel like my health was his major concern. Since the surgery, he has not stop given me the care I need. He was great with my family and I am glad I choose him as my doctor.

I can truly say I have no complaints about Dr. Dyer or his staff. From the seminar he presented, to the post op treatment I received, he was first rate. Dr. Dyer answered all of my questions (and my wife's) thoroughly and with the utmost patience. Joanna and Robin were also so kind and caring whenever my wife or I called the office with a concern. There is no way I could list everything Dr. Dyer did for me through out this whole process!
I also want to take this chance to thank the entire nursing staff in the Womens Hospital at Centennial. There is no way to name them all, but each and every one was wonderful! We did not have one nurse that wasn't a friend by the time we left.
Thanks to Eloise Bray and Pam Davis for helping me start the whole process and for holding my hand throughout.
My surgery was February the 11th and I have lost an amazing 125 pounds! Knowing what I know now, I wouldn't change one thing about who I chose for surgery and where.
Thank You Dr. Dyer for the changes you have helped me make in my life!

I really liked Dr. Dyer. His staff has been excellent with all my questions. He explained everything well, and made sure that I was ready for this change in my life. They got the approval from my insurance in about 3 weeks. I hope to have a date within a few days.

I had a Gastric Bypass three and a half months ago. I have lost 85 lbs. since then and I haven’t bottomed out yet. After the back pain and being out of breath from activity due to being overweight, I now feel fantastic.

Although I originally consulted with a different doctor in the office, picked via a friend’s recommendation, we were unable to schedule the surgery conveniently. Dr. Dyer’s schedule had an opening at the right time for me and he came into the office that day to consult with me so I wouldn’t have to return for an appointment on a different day. He took the time to fully explain the procedure in detail and on what I should expect post-surgery.

Dr. Dyer again took the time the morning of surgery to speak with me and explain the sequence of events and helped to calm me down when I questioned if I was about to do the right thing. The actual surgery took longer than expected due to issues from a prior surgical procedure, but the bypass was completed laproscopically and prior issues were corrected. Dr. Dyer spoke with my family and informed them why the surgery took so long. Hospital staff was caring and attentive.

Follow-up visits to the office are met with smiling faces from the staff and Dr. Dyer continues to encourage my progress. My experience through the entire program has been great - from the first informational seminar to my most recent followup visit.

I have had no adverse effects from the surgery at all. I wouldn’t tell anyone there aren’t BRIEF moments where you may question your choice and it has been strange to experience this new relationship I have (or don’t have) with food. But to this point, I have absolutely no regrets and I would recommend Dr. Dyer to anyone seeking to create a more healthful life through weight loss surgery.
