James Grosek, PA-C

James Grosek, PA-C, MPAS, is a board-certified Physician Assistant with nearly a decade of clinical experience and a passion for helping patients achieve better health through quality sleep. He began his career in biomedical research at the Medical College of Wisconsin before transitioning to direct patient care—his true calling. He earned his Master of Physician Assistant Studies from the Massachusetts College of Pharmacy and Health Sciences in Boston, where he also completed a transformative clinical rotation in San Ignacio, Belize—an experience that continues to shape his compassionate, patient-centered approach.

James brings a diverse clinical background, having worked in a Level 1 trauma center at Albany Medical Center and across internal medicine and urgent care practices in southern Massachusetts and Rhode Island. After relocating to Arizona in 2019, he discovered a strong interest in Otolaryngology (ENT), completing a fellowship in Head & Neck Surgery and Cancer at the Mayo Clinic. He then spent three years serving patients in a rural ENT clinic, managing conditions including allergies, hearing loss, general ENT issues, and sleep disorders.

Outside the clinic, James shares life with his fiancée Suzanne—also a Wisconsin native—and they’re planning to marry in October 2025. Raised in a restaurant family, he’s an avid home chef who enjoys experimenting in the kitchen and behind the grill. An outdoor enthusiast, James spends his weekends mountain biking, hiking, cycling, swimming, and playing disc golf with friends. A passionate traveler, he’s on a mission to visit every U.S. national park—and he’s already checked off more than half.

At the Insomnia and Sleep Institute of Arizona in Scottsdale, James is especially fulfilled by helping patients restore restful sleep and improve their overall quality of life.
