What people say about us

Sally Murphy
I thought you'd be happy to know that I worked hard for 5 hours in the garden yesterday and 2 hours this morning (getting ready to have garden waste hauled away) and my back is doing well. I'm so pleased as this is the first time in almost 7 years that I've been able to work hard in the garden for a long stretch.
Shannon Ogilvie
Both Ashleigh's workout plans and nutrition tips were basic and extremely effective.  I came to visit and live with Ashleigh for one week over spring break and felt that I needed a total overhaul of my life habits.  In one week I went from feeling sluggish and stuck in a fitness routine that wasn't working to losing 6lbs and feeling super energized and ready to attack my next fitness challenge!
Joanie M
Your class was great and you are an AWESOME teacher.  I learned more in your class than in all the books I read on health...thank you.
Linda S
I feel 500x better than I did when we began working together a few months ago.  Initially I was having problems with back pain and knee pain, and a body that generally just hurt.  My body feels so much healthier, I am sleeping well again, my attitude has improved, and my outlook on life is great.  You have been a blessing in my life Ashleigh!

Martin Reader
She is kind, motivated and her energy is contagious; improving the lives of anybody she is in contact with. I couldn’t have asked for a better person to help elevate me to where I am today.
