To discuss your situation with a school representative, you should reach out to Vista Academy directly. The number for their main office is (720) 423-7600. You can also read more about the school on their website, where they describe their academic programs and their mission "to identify, address, and move past performance barriers allowing students to regain their academic success." If you haven't already, you could also try speaking with a counselor at DSST Green Valley Ranch High School about what recommendations they might have. Their phone number is (303) 524-6300.
Noodle's school search tool is a great way to start researching high schools in the Denver area, and allows you to filter by school type (public, private, charter), characteristics (alternative, Montessori, special needs), school district, and more. Once you've identified some schools that might be a good fit, you should contact them directly to discuss your situation and find out about how they might be able to help your student.
