I love Dr. O. He seriously is a great doctor. He is very caring, empathetic, down to earth, and a knowledgeable am deathly intelligent man. He's farthest thing from being judgmental, and he gives you an overwhelming sense of comfort whenever you're in his presence and under his care. He is just all around a great person.

Dr. Onishchuk is a fine doctor. He is non-judgemental and spends as much time as one needs in order all aspects of a problem are addressed. He is a caring individual who tailors his tratment program to each patient's idiosynchrasies.

He is kind,understanding, he listens and he cares, immensely. I have been to many doctors over the past 6 years. I thank my husband daily for finding this man. I believe my father who passed when I was young, hand picked Mike, my husband and in turn he found Dr. O. It's a blessing. The office staff is just as kind. They took me same day, and with 3 Dr.'s, they take you asap, no long waits.
