Nutritional Health for a Lifetime

At AFM, we use our advanced knowledge of medicine, nutrition, and dietetics to provide comprehensive nutritional guidance for patients with a variety of concerns. You will receive dietary advice and guidance that adapts to your changing nutritional needs. As with every other area of our expertise, we are committed to not only addressing nutrition and health problems as they occur but preventing future complications with a holistic approach for a lifetime of good health.

Adult Weight Loss

Some patients find that maintaining a healthy weight becomes increasingly difficult as they age. We’ll develop a nutrition strategy that helps you achieve your ideal weight through a combination of healthy eating, regular exercise and preventive care.

Pediatric Nutrition

Giving children the right foods and encouraging them to exercise can be a challenge in an age of conflicting and sometimes confusing research and changing recommendations from governments and community organizations. We have the knowledge and experience to answer all the questions you may have about your child’s nutritional health and can develop a healthy eating plan that works for your entire family.

Specialized Nutrition

We specialize in treating patients with complex issues like:

  • Diabetes
  • Obesity
  • High cholesterol and high blood pressure
  • Celiac disease
  • Food sensitivities and allergies
