Dr. Halupka definitely knows his stuff. He’s a fairly new to practicing at Pleasanton, but don’t let him being new fool you. Dr. Halupka was able to answer all of my questions about my contacts and also went into deep detail about all the products out on the market and their effectiveness. From the way he presented himself you can tell he is not in it simply for the sale, he cares about his patients. He is a very professional man and carries conversations as normally as one can between a patient and doctor without coming off as if he thinks he’s better than you. Bottomline, I recommend him if you are looking for an eye doctor that is not only knowledgeable but fairly down to earth as well.
