As a clinical nutritionist, I offer individual nutritional counseling to help you make practical and sustainable changes specifically addressing your issues through a healthy lifestyle. You'll experience optimal health and wellness when your body functions are in balance. In our fast-paced, convenience focused lives, we are faced with many obstacles that take us off course-our lifestyle and the quality of our foods, for example. I specialize in gastrointestinal wellness and detoxification support. Gastrointestinal health plays a central role in all other body systems, while support of the body's detoxification mechanisms is critical in our world today.

My ideal client feels stuck between wanting to improve their body composition and not wanting to fall back into restrictive, all-or-nothing patterns. They may have a history of dieting or disordered eating, struggle with consistency, and feel frustrated that what “should” work isn’t working. They want a realistic, sustainable approach that supports their metabolism, strength, and long-term health without extremes, rigid rules, or sacrificing their relationship with food.

Do you suffer from symptoms related to food sensitivities, but are unable to pinpoint exactly how or which foods? Do you have chronic health conditions related to inflammation, such as IBS, Migraines, Fibromyalgia, Rheumatoid Arthritis, Colitis, or others? Your everyday foods can often provoke these conditions. As a Registered & Licensed Dietitian who is also a Certified LEAP Therapist, I use the MRT lab-assisted elimination diet to help treat your symptoms related to food intolerances. Having worked in OB/Gyne for 20+ years, I also specialize in all aspects of women's health, from pregnancy to menopause and more.

My team and I have training in functional and integrative nutrition.
Does this sound familiar? You are busy, overstretched and tired of not recognizing yourself when you look in the mirror? Do you give so much to others, family, organizations and work that there is nothing left for yourself at the end of the day? Is your energy, vitality and health being chipped away little by little? Have challenges such as Whole 30, Hard 75 and intense diets failed you?
