Why Our One-on-One Works
Many students struggle with online classes, in big classroom settings. Questions go unanswered, lessons drift off-topic, and materials feel overwhelming. Our program is different. At Mass. CSL Training Group, you get personalized attention and detailed, one-on-one coaching with David A. Johnson, Sr., CBO a building code professional and former teacher with 45 + years experience.
We also offer materials in other languages upon request: spanish, vietnamese, portuguese and many others, and can provide customized group classes for construction companies or other groups.
You are not just a number to us like the big class room settings. We are local, not a online provider.
We stay with you until you pass the test at no additional cost.
