About Supervision with Kristine
Kristine’s approach will be didactic and educational in nature but will foster critical thinking, curiosity, and inquisition. She loves to teach with metaphor, storytelling, and humor. She will combine evidence- based nutrition principles with ED theory so the supervisor will be able to develop and strengthen their skills to be able to view a situation with a strong clinical yet therapeutic comprehensive lens.

Kristine supports wellness and total quality of life (WTQL), her own approach to assisting clients with lifestyle changes that support their values, not her own. In her career, she has seen many approaches to wellness that have proven to be both harmful and beneficial. She will address these issues throughout your supervision experience. She will assist you with learning the art of applying evidence-based practices and theory while preserving the person’s overall wellbeing. In Supervision she will present to you the pros and the cons of the most common treatment approaches and help you develop confidence with your own clinical judgment. She will teach empathy and compassion and the right timing for a firmer more direct hand. She will offer the resources to support what she teaches, and she will give you an opportunity to share, consult, laugh and maybe even cry about your own experiences treating individuals with eating disorders. Kristine values validation and empowerment and loves to guide and support others desiring to learn about how to best support others in their journey to recovery. Confidence is key!
Together you and Kristine will build skills that you as a Dietitian can use to make you feel more confident, more knowledgeable, and help you navigate your way confidently as an Eating Disorder Specialist.
Clinical Specialties and Approach
Sinnergy Wellness Group was founded by Kristine who has been working with eating disorders exclusively for over 30 years. Her group offers adolescents and adults with eating disorders help for Anorexia Nervosa, Avoidant Restrictive Food Intake Disorder (ARFID), Bulimia Nervosa, Binge Eating Disorder, Diabulimia, Orthorexia, Exercise Addiction and Sports Nutrition. Kristine specializes in complex high risk and severely compromised cases. She possesses the critical care experience needed to take on cases at an outpatient level that would traditionally require a higher level of care. Kristine believes everyone deserves treatment and will do whatever she can to help those who need help but cannot otherwise find what they need.

She is a medical nutrition therapist and clinical Dietitian. She uses only evidence-based practices, and her focus is overall wellness. She does not conform to any one approach to eating and wellness but will instead carefully assess the best approach for the individual. Her philosophy on weight issues supports a numbers neutral approach and addresses each person's desire for improved quality of life individually, carefully, and thoughtfully. She will present the pros and cons of each treatment modality and help you think outside the box. She will teach proper application and timing for each type of nutrition related theories and applications. Her areas of expertise are in the nutritionally compromised, binge eating disorder and she is specialized in the refeeding process.

Supervision Philosophy

When you come to a supervised session, Kristine’s primary philosophy is to always keep an open mind and think before you do.  Critical thinking will be emphasized.

  • Provide resources for further learning and guidance.
  • Discuss the importance of working as a treatment team and how this can support referrals.
  • Discuss and work on the formal case study for the CEDS application as well as information as needed for the exam or to support you in the application process.
  • Discuss career goals, growing your practice and niching into your specialty area.
