I cannot say anything but good (great actually) about Dr. Gasser and his staff ... My case had many unforeseen problems and they were taken care of right away if not sooner to be honest ... Dr.Gasser had to make more than one trip back to his office to attend to a problem that was actually caused by the people in my Cardiologists office (Coumadin Clinic) which prompted and was the cause of excessive bleeding on two different occasions ... Dr Gasser worked late into the night to get the bleeding stopped and put several extra stitches in to keep there from being any more problems ... I took my time and did a lot of research before making the leap into the all on 4 procedure, am glad I did ... Dr Gasser to this day still does follow ups to make sure everything is as it should be ... If I could give 10 Stars I would do it without hesitation ...
