Blackburn Mentoring gives Diamond Bar and Walnut students one dedicated mentor who helps with planning, routines, follow through and confidence, mostly by video with in person sessions in Los Angeles when they help. For high school students a parent can join the free 20 minute intro call and get regular updates. Mentors do not tutor or promise outcomes; they help students take ownership of a demanding week.
The school picture in Diamond Bar and Walnut
The Walnut Valley Unified School District serves most of Walnut and the southern part of Diamond Bar; other parts of Diamond Bar fall in a neighboring district, so families should check their address. Walnut Valley Unified enrolled 14,302 students in 2025 to 2026 according to Ed-Data, the K to 12 data partnership that includes the California Department of Education. Academics are taken seriously in both cities, and students often carry advanced classes, music and activities at the same time.
Both communities are more international than Los Angeles County as a whole. According to the U.S. Census Bureau, 47.3% of Diamond Bar residents and 51.9% of Walnut residents were born outside the United States, and 63.3% and 68.3% speak a language other than English at home (county: 33.4% and 55.1%). Adults are well educated too: 52.8% in Diamond Bar and 57.3% in Walnut hold a bachelor’s degree or higher, against 36.0% countywide (American Community Survey, 2020 to 2024).
What students and parents here bring to a mentor
- High expectations, little slack. A student who is doing well but has no margin, so one hard week sets off a chain of missed work. A mentor builds a plan with buffer in it.
- Two cultures, one calendar. Family obligations, weekend language or heritage programs and school all compete for time. Mentors help students plan honestly around all of it.
- Parents navigating the system. Many parents were educated elsewhere and want clear information about course planning, A to G requirements and college timelines. Our high school to college calendar is a good start.
- Confidence and voice. Students who rarely ask teachers for help learn to email, use office hours and advocate for themselves. See working with your school counselor.
- Commuting to college. Students living at home while attending a nearby university or community college need structure that a dorm would otherwise provide. See mentoring for college students.
Hillside suburbs and long drives
Diamond Bar and Walnut sit in the hills at the eastern edge of the county, where the 57 and the 60 meet. Many parents commute long distances, and teens depend on rides until they drive. That is one reason video mentoring works so well here: no one has to be driven anywhere for a session, and a student can meet from home after practice.
In person or by video
Our team is based in Los Angeles. Most Diamond Bar and Walnut students meet by video and add in person sessions in Los Angeles when it is worth the drive, at a convenient, appropriate place agreed on the intro call. Mentors stay reachable by text and phone between sessions, with evening and weekend times available.
