Dr. Kristo was very responsive about my concerns regarding the provider of my current respiratory equipment and was extremely helpful with advice about a new supplier. He made sure that before leaving his office I spoke to Lupe who specializes in dealings with insurance, providers and equipment. This was very reassuring to me and made me feel confident that I would be well taken care of.
