Melissa LaHaie

Coach/Personal Trainer/Office Manager

Melissa is our resident shutterbug, sparkplug and free spirit. While she’s always been active and on the go from her roots in Northern Michigan, her greater passion for fitness started shortly after giving birth to her second son, when she decided to challenge herself and train for a Spartan Race and never looked back on her passion points.

Not long after tackling that race, she set her sights on getting her personal training certifications and recently enrolled in NASM’s Fitness Nutrition Specialist Program.

Melissa is a wedding photographer, a mother to a pair of feisty boys (Max & Miles) and a lover of the beach, the trail and travel. She’s a huge advocate for self-care, Target and pushing herself and others to find new plateaus in their potential.

Melissa currently serves Grit Life and its members as a personal trainer, coach, social media manager and office manager.
