What college are you going to attend? It's been my experience as a flight instructor at a 141 university that students who arrive with prior part 61 flight training were probably better off without it. This is not always the case though. Some, but few were better for it.
In primary flight training consistency is valuable. Same flight instructor, same aircraft, same airport, etc. Later on, after you have built a solid foundation (around the Private Pilot level) it's good to fly with other instructors and other aircraft in changing environments in order learn different perspectives and techniques. It helps you grow as an experienced pilot.
It is only my opinion, but as a Flight Instructor and graduate of a University with an accredited and well-established part 141 flight school, I would recommend that you wait until you get to college if it's within a month or so. Good luck!
