Founder · Board-Certified Family Nurse Practitioner · Springfield, IL
Family nurse practitioner with 35 years in nursing, founder of Vital Glow MediSpa / VGM Health.

Diane Lietz, MSN, APRN, FNP-C, has been caring for others for over 12 years as a board-certified family nurse practitioner, but her passion for helping people goes back even further. Growing up in a small farming community in central Illinois, Diane learned early on the value of hard work, compassion, and community. After earning her bachelor’s degree in nursing from Lewis University, she began her journey as an RN, diving into the world of cardiac and intensive care, emergency medicine, and occupational health.
Through her 35 years as a nurse, Diane has always been passionate about empowering her patients, whether it’s helping them manage chronic conditions, recover from illness, or find their way to better health. She later earned her master’s degree as a Family Nurse Practitioner from Graceland University, allowing her to expand her ability to provide comprehensive, personalized care.
At Vital Glow MediSpa, Diane is excited to offer a range of services, from weight loss management and wellness counseling to addressing both men’s and women’s health concerns. She understands that everyone’s health journey is unique, and she’s committed to being there for her patients every step of the way.
