The PN Level 2 Master Health Coaching Certification is an advanced, practice-based program designed for coaches who want to work at a deeper level—and do it sooner than the traditional 5–10 year path.

It’s a mentored, small-group experience that prepares you to:
- Work confidently with complex client realities like stress, mental health, and emotional setbacks
- Apply behavior change principles that hold up when life gets messy
- Understand clients beyond food and fitness—so change actually lasts
You’ll learn directly from PN’s most experienced coaches through weekly live mentorship, structured self-study, and real-world coaching practice.
Why it matters
Level 2 is NBHWC-approved, making graduates eligible for:
- National Board Certification through the NBHWC
- Professional membership with the Health Coaches Alliance (HCA)
These credentials expand your career options and set you apart in an increasingly crowded field.
