My experience at ACHS was nothing short of excellent. From the admissions process to my last course, every person along the way ensured that I was on track and had everything I needed to excel. I feel prepared to embark on my professional journey as a nutrition consultant and will apply all that I learned to help my clients achieve sustainable, optimal health.

It was once said that, ‘Education is the most powerful weapon, which you can use to change the world.’ ACHS has given me the skills and knowledge to not only assist others in achieving their health goals, but also change how others view alternative medicine.

The AAS in Health and Wellness program at ACHS absolutely changed my life. I run my own spiritual wellness business where I’ve taken everything I’ve learned while at ACHS to empower other women to live fulfilling lives. Although I completed my degree program, I have my sights set on a few more courses I can’t wait to take through ACHS.

I highly recommend to those considering exploring alternative medicine to seriously consider an education with the American College of Healthcare Sciences. You won't be disappointed. Quite the opposite. The education I received is priceless and is of benefit to so many. I am using what I've learned to share with others. My experience with ACHS is one I have treasured and I am very proud to be a graduate of this organization.

All of my interactions with the ACHS administrative team have been extremely positive. My advisor (Joel Strimling) has always responded quickly to any issues/concerns, and when he was out of the office, his back-up (Melissa Trujillo) followed up with me immediately. I've interacted with other staff as well, and have always been impressed with how friendly, courteous, and efficient everyone is. Great support all around!
