“I was nervous going into this appointment, but my experience was very positive. Everyone in the office was professional, kind, and friendly. The office and facilities were welcoming. They were very busy, but the wait was minimal. Everyone took a moment to explain what would happen next, as I had a few diagnostic tests that needed to be completed in different rooms with various equipment. The Dr. was very knowledgable and personable. Would highly recommend this practice.”

“I ended up seeing a different provider - the office called me prior because the original doctor I booked with is more of a specialist for an issue I didn't have - and the doctor they booked me with, Dr. Kellar, was absolutely lovely. The whole experience was seamless: quick, clean, and kind. I never felt rushed, but they have their system down to a science. ”

The very first encounter was with the customer service representative who was mannerly, courteous, professional and explained everything to me as a guide of the administrative process. Highly pleased!
The technicians were very professional and made me feel comfortable Hilo taking pictures and being prepared for the next step.
The nurse interviewed me with the proper questions that would definitely describe my current health condition, medications being taken and so on.
The Doctor was phenomenal, showed me pictures of my inner eyes and explained what everything signified in his diagnosis. Great job!
