Patient Reviews
Jun 28, 2022
Dr. Hasler successfully diagnosed me with celiac disease long after many doctors would have sent me on my way with an IBS diagnosis. Thanks to him I was able to confidently adopt a gluten free diet and I got my health back. Years later, I still think about how lucky I was to get a doctor that was so knowledgeable about the space and willing to do the work to identify the problem. Throughout, he took the time to hear everything I had to say and explained all of the tests he was having done. My first appointment, one of the nurses warned me "Dr. Hasler is running way behind, so you'll be waiting a while, but it's because he's the best doctor here and he takes to time to talk to all of his patients", so I just made myself comfortable with a book. It was worth it. Dr. Hasler, I hope you read this someday so you know how grateful I am for you.
