I found the whole process very informative which helped me to choose the right weight loss surgery for me. From the ever helpful Marianne keeping me up to date on the process and Mo Atalla gave me all the info I needed to make an informed decisions. I could not recommend BetterLife surgery enough.

Mo and his team have changed my life forever. Dealing with me in a holistic way when looking at the reasons behind my weight gain and life long struggles has been amazing. Other surgeons saw me as $$ only. My dietician could have given more tips earlier throughout my journey but Mo’s nursing team were amazing and stepped in to help. Marianne is always on the ball coordinating all aspects of my care. 32kgs down and lost forever and hoping another 10kg coming up.

I highly recommend Mr Attala. So far I have had a colonoscopy, gastroscopy and gastric sleeve surgery. Next up is having my gall bladder out. On all occasions I found Mr Attala calm, professional and non-judgemental, making a reasonably scary process a lot more reassuring and easier to process. I was fully informed and felt safe and comfortable in his hands. Mr Atalla also has a great team working with him. Marianne handles all appointments, paperwork and all the fiddly details, promptly and efficiently, and keeps you up to date with all the details. Bec, a nurse practitioner / dietician specialises in weight loss dietetics, and is there to assist both before and after the surgery. Bec is also calm, professional, non-judgemental and is practical and realistic in expectations of your diet transition after the surgery. If you are looking for weight loss surgery, look no further.

Had Gastric Sleeve surgery with Mo Atalla in October 2023. The whole process went very smoothly, not just down to his skills as a surgeon, but with the professionalism and care of him all his team. From initial consultation through to post-op follow ups, the holistic approach involving surgeon, dietician, nurse practicioner, and admin, provided all the advice and reassurance I needed (also had access to a psychologist through the practice, but didn't use). There were no unwelcome surprises either financially or surgery-wise. A special mention to the Practice Manager, Marianne, who was terrific in keeping me completely informed throughout the process and handling any queries. I was fortunate in that there were no complications (in no small part due to the above), but am sure that if there had been, they would have been very well handled. I would recommend the procedure to anyone wanting to change their life with weight-loss surgery, and could not recommend Mo and his team more highly. Thanks & Well Done to All

Their is not enough stars available to give Mo and his team, they are super amazing. The whole process was made so easy. Mo is so attentive to his patients, talks you through everything, nothing left unsaid and makes you feel at ease, and Marianne WOW I adore her, she is available to assist at any time, she is so knowledgeable, caring and helpful, always makes herself available throughout the process. They really are the dream team. To them you are not just a number, they actually care about you, before during and well after surgery. My surgery was much harder than Mo thought, it certainly tested his skills, but he did not give up on me and got the job done with great success. One year on I am down 32kg and cannot be happier. I would highly recommend to anyone wanting to look at having weight loss surgery. So much love for Mo and his team, I thank you all from the bottom of my heart.
I first saw Mr Atalla for a General Surgery procedure back in 2021. Even though I live in Melbourne I travelled to Echuca for the procedure as through research I found him to be the best at what he does. As my first point of contact, his Practice Manager Marianne was absolutely wonderful. The professionalism & information she provided whilst booking my appointment was also one of the reasons I chose him. Mr Atalla was amazing at my consultation appointment & Marianne was so kind & helpful. The whole process was smooth & put me at ease Mr Atalla is now my go to General Surgeon for all general procedures. I couldn’t recommend Mr Atalla & his Practice Manager Marianne enough.

I’ve spent years trying to find the right path toward being healthy & happy with myself. For a long time I was stuck on a loop taking me nowhere. I focused on medical labels that defined me as disabled thanks to my rheumatoid arthritis, (this was just an excuse to stay stuck). Then I found Mo Atallas website & decided to visit him & see what he could offer me. From the moment I walked into his rooms I felt at ease. His admin; Marianne has the friendliest personality & is so genuine & helpful. Then there is Mo Atalla; now he doesn’t offer any magic wand surgery, because there is no such thing. He offers the honest reality that he can help with surgery as a tool toward better weight & better health; but only if you are prepared to work hard on both body and mind. Mo and his team helped me with the tools and the support to put the hard yards in. Better Life Surgery helped me to find who I want to be, not just by losing 46kg with my gastric sleeve surgery, but by finding confidence in myself, getting my health back, adding years onto my life & most of all becoming a happier person again! Every time I visit the clinic I feel like supported in my journey and am told how proud they are of my achievements. I am not just a number to this team and you won’t be either. Thank you Mo, Marianne, Bec & Bec at BetterLife Surgery Liz

I couldn’t have had a better experience with the Better Life Surgery team. I have reached my goal weight in 7 months after having the gastric sleeve. Mo and Maryanne have great attention to detail and are right onto everything including the paperwork aspect. I feel very grateful to the team for helping me turn my life around for myself and my family. I could not have done this without them.
