Parker Pediatrics is awesome in particular Dr. Stanga. Dr. Robert Boraz is a really great kids dentist and he has an office in Parker and in Castle Rock, truly awesome guy. Sorry, dont know a great place for a hair cut. For Adult Dr I go to Dr. Staar-Kumosa, she is in the Parker Adventist Hospital, she is a great DR, though sometimes it can be a wait to see her, and I dont know any Chiropractor's sorry.
If you like sushi, then Junz is just an awesome restaurant, the wildlife experience is a fun little museum that is close by, it is my sons favorite though he wont be 4 till next month but it is a fun place!
Good Luck with everything! Hope you enjoy it here!
Oh, yeah there is a nice little famers market on main st on sundays I think from 8-1 (only goes through Oct I think, check out parkers website, it might have more info). Not really big but I think it is pretty nice, there is also a nice park there for kids on main street and parker (and its right across the street from a baskin robbins)! yum!
