ACT Prep Cherry Creek High school

I am a parent of a Cherry Creek High senior and looking for a local community that helps prep for the ACT exam. Is there anything available in the area that helps prep for the exam in person? I looked at multiple tutoring schools in the area and spoke to the school counselor but couldn't find a credible tutoring resource. Counselor advised to look within the parent community of the school district. 

Does anybody know of a good ACT prep resource? 

Thank you in advance!
