Who Is Marissa

Marissa’s passion for nutrition evolved when she was in high school and began learning the important role that food could play in the prevention or management of  certain medical conditions. She decided to pursue her passion on a professional level and study Nutrition Science in college, which would lead her to become a Registered Dietitian Nutritionist (RDN).

Since she was a young girl, physical activity was always a part of her life, from  

figure skating to  gymnastics, dance, jogging and being a self proclaimed “gym rat” 

in her later years. Due to her past and present interest in exercising for physical and mental health benefits, she has always had a strong interest in learning about how proper nutrition and hydration is imperative for fueling the body for optimal exercise performance and recovery.

Her interest has also evolved to use a HAES and IE approach to counseling, which has been shown to be more effective for her clients.

Marissa earned her BSFCS with a major in Nutritional Sciences from Baylor University. She then continued on to complete an accredited dietetic internship(DI) at Glendale Memorial Hospital and Health center, which involved supervised dietetic practices at clinical, food service and outpatient settings. Upon graduating from the DI, she was eligible to sit for the national exam set forth by the commission on dietetic registration (CDR)and successfully passed, thus earning the credentials "RD" (or "RDN”). Marissa actively studies to stay abreast on the most current evidence based dietetics research to offer her patients clear and correct information to help them manage their health. Marissa also maintains her RD license by completing at least 75 hours of continuing education every 5 years.

Marissa takes a non-diet approach to counseling. This means that she teaches her clients to take the time to listen to their bodies, and to fuel themselves with food that is nutritious and tastes good (i.e. all foods fit). Time is also spent on noticing how physical activity, mindfulness, and emotional awareness plays a part in their overall wellness. With this approach she is able to guide her clients to a balanced and happy way of living, rather than a rigid way of eating and exercising that can lead to stress and emotional imbalance.

Marissa has over 13 years working as a Registered Dietitian. Her work experience has included Davita Healthcare Partners, Head Start programs, Morrison Community Living, and  The Salvation Army. She has experience working one on one with adults, adolescents, and families seeking management of diabetes, kidney disease, food allergies, GI challenges, disordered eating and eating disorders, and those with general wellness concerns. She also presents various nutrition workshops to groups. She is a member of the Academy of Nutrition and Dietetics and the California Academy of Nutrition and Dietetics. She is also a member of the following practice groups: International Federation of Eating Disorder Dietitians (IFEDD), Nutrition Entrepreneurs (NE), Dietitians in Integrative and Functional Medicine (DIFM).

".....I know my lab reports have gotten better because of my diet.  Marissa is an excellent dietician who is very patient.  I know that without the diet that she has me on, I would be on dialysis.I am an advocate for anyone that I know who has kidney problems.  I tell them what Marissa Martorana has done for me and that your diet has a lot to do with your health."

"I hired Marissa to provide consulting services for the LAEP Early Head Start program. She addressed the nutrition referrals and provided parents with nutrition education. Marissa also created a variety of menus and a nutrition education booklet to meet the needs of the program. She also created nutrition policies and procedures for the program and provided staff training. She is professional to work with and I would highly recommend Marissa for nutrition consulting services."
