My Professional Experience

I’m the president and sole proprietor of Cassens Associates – Diversified Nutrition Management Systems, a firm providing a variety of wide-ranging nutrition and dietetics services to private individuals and long-term care institutions. I'm an author with three published books as well as articles ranging from professional topics to nutrition related blogs. 


In my private practice I provide general nutrition, wellness and chronic disease counseling to individuals and groups with absolute confidentiality virtually  in the comfort of your home. I accept some insurance plans or provide you with a detailed invoice so you can seek reimbursement from your insurance company. Contact me for details and to discuss your nutrition and wellness needs. 


As an independent consultant my experience is broad and varied. I have helped open and provide consulting services to group homes for adults (CCRC) and independent living communities such as Residential and Assisted Living centers. Contact me for your consulting needs.


Working in all levels of long-term care with positions in middle and senior management for some of the largest public and private companies helped develop several specialties. I specialize in project management, cost-effective food production management, safety and sanitation systems, policies and procedures development, and systems to ensure budgetary and regulatory compliance.  My hands-on approach leads to successful results because I understand the human factor in any situation and apply the appropriate techniques that allow working under extreme pressures at a rapid pace. Contact me for your pre-survey needs.

My Uniqueness

Living with my husband of 50+ years on a small ranch in the Mojave Desert of Southern California, we enjoy baking ancient grain breads, cooking, growing fruit trees, chiles and organic vegetables. We love nature walks in the desert and off-road trips exploring the area. We have 3 daughters, 5 grandchildren, and an assorted and always changing menagerie of rescued dogs, cats, turtles, frogs, fish, crayfish and exotic lizards.
