Meet the Founders


Our motto at Whole Cruzine, is that Life is a Balancing Act. What we do, wish for and accomplish is all based on the balance between effort and pleasure. Linzi's history in bariatrics and medical weight loss, initially led the focus of the practice to serve the weight loss surgery population. However, as time passed, more individuals sought her guidance who wanted to take action BEFORE needing the the option of bariatric surgery. This demand has developed Whole Cruzine's service as the disease prevention specialist and our mission is to help many more individuals with their whole body health in Austin!
