Marcela Carranza, Psy.D., is a licensed clinical psychologist in Florida, Massachusetts, Iowa, and Virginia, an entrepreneur, and the creator of the Dumbbell Method™ — the flagship offering of Vertical Fit.

Across years of clinical practice with individuals navigating emotional, behavioral, and relationship challenges, she kept encountering the same failure point: approaches that managed symptoms while leaving the cause untouched. People got relief. They didn't get resolution. The Dumbbell Method™ was built to close that gap.

The method rests on three principles — root-cause exploration, pattern recognition, and actionable change — and is designed to move people past insight alone. Awareness is the starting point; the method converts it into execution.

Her premise is simple: lasting transformation begins when people understand not just what is happening in their lives, but why it keeps happening.

Beyond her clinical work, Dr. Carranza is the Founder and CEO of Prende Inc., a technology company building infrastructure for unlocking human potential.
