Melissa Harris is Personality Hacker’s Advanced Profiling Coach.

Once a PT Student herself, she’s spent years obsessing over how to become a better profiler, and has enthusiastically sought opportunities to help people recognize their unique gifts and unapologetically share them with the world.

Melissa has conducted thousands of profiling sessions over the years and she’s been the mentor of countless profiling students for the last 5+ years, helping them in building robust and calibrated profiling skills and conduct high-quality profiling sessions.

Since 2018, Melissa has spent about 60 hours per week working on personality-related topics. A lot of her free time is spent crafting mental models and testing them to refine her understanding of the 16 types.

She’s come up with tried and tested tools, applied at scale in profiling sessions to help address all the components of powerful profiling sessions (i.e. – how to land a good explanation, rapport building, data rapport, tie-breaker questions, type calibration etc.)

She has built and designed multiple courses and Profiling programs for the Personality Hacker community. All the programs are based in Melissa’s massive knowledge that she has gained from years of profiling and teaching students the skills of becoming a better profiler.

In her personal life, Melissa is a professional pianist, teacher, choreographer, and mother of four in Portland, OR.
