Dr. Grewal and his family enjoy spending time outdoors and traveling. Dr. Grewal has had an immense interest in sports ever since his high school years. He watches and keeps up with all the football, baseball and basketball games and is a big Chicago Bulls and Bears fan at heart (true to his roots).

He has an endearing personality and loves talking to people and getting to know them.
