What are students saying?

The Aromatherapy program offered me the opportunity to obtain a formal education in my favorite subject area while working full-time. I found the curriculum to be informative and appropriately challenging. The faculty was knowledgeable and approachable. I'm excited to reinvent my career using my degree milestone with ACHS as a significant first step!

Master of Science in Aromatherapy

I’ve been writing professionally for three decades, but in recent years have shifted my focus. I’m asking fewer questions about various business topics and more questions of those taking part in the conversation, especially considering habits, change, stress, resilience and hope. I became a Certified Health and Wellness Coach through Wellcoaches in early 2019, and opened my coaching business, Gates Open Wellness, not long after. My concurrent studies with ACHS—a Certificate in Wellness Consulting—have helped me fill in gaps of knowledge in terms of stress management, sports nutrition, holistic pathophysiology, business practices and integrative health. Altogether, it’s been a great experience!

Certificate in Wellness Consulting

Over the past three years during my studies at ACHS, I was able to bring my passion for holistic health to life. I have learned valuable information that will allow me to begin my goal of becoming a holistic lifestyle coach by teaching others to integrate nutrition, herbs, and mindfulness into their lifestyles.
