Dr. O'Reilly is an EXCELLENT surgeon and I trust him 100%. Leigh is a wonderful and caring Medical Assistant. Both are VERY friendly and a "joy" to have as part of my medical care team. I have recommended Dr. O'Reilly to several people. I know two people have seen him based upon my recommendation and experiences with him. Leigh is a lovely person as is Dr. O'Reilly.

Dr O'Reilly is an impeccable surgeon. I suffered with acid reflux for 25 years. I have been on two types of acid reflux medicines for these 25 years. Since my surgery not only did Dr O'Reilly fix the problem I have not had to take one acid reflux medicine period. I will forever be indebted to Dr O'Reilly and his staff.
