Our Team

Caren Marshall


I am a Certified Lifestyle Professional, a Certified Health Coach and a Master’s Degreed Social Worker. I graduated from Indiana University Graduate School of Social Work with a year long internship at the Indiana University Medical Center. Following a lengthy career as a Medical Social Worker in the field of Physical Rehabilitation and a CEO in Non-Profit Management, I joined Renovare Wellness By Design in 2009. I trained with Dr. Timothy Gerhart and I graduated from the Institute of Integrative Nutrition in New York City in 2012.

By designing meal plans recipes that meet specific requirements for allergy free, healthy nutrition.

I teach individuals and groups how to find new and delicious sources of powerful nutrition. I support patients in easing into new and healthy eating patterns.

I administer and interpret Body Composition and Metabolism testing that provides a measurement of changes in a patient’s toxicity level, body mass and body fat percentage. The BCM testing measures a patient’s progress or provides results that indicate a needed change in a patient’s lifestyle plan.

Helping patients put together all the pieces of LifeStyle Change is my passion. Supporting people in good nutrition, excellent sleep, pleasant exercise, de-stressing and smart supplementing brings them new a new lease on life. I embrace the Renovare philosophy which guides patients in setting and achieving their own goals while using time tested and research based techniques. I have a rewarding career at Renovare Wellness By Design where I see people enjoy renewed energy, hope and healing.

Gina Day


My name is Gina Day and I am a Certified Emotional Freedom Technique Practitioner, Matrix Reimprinting Practitioner, Certified Health Coach, Certified Chiropractic Assistance and a member of the American Association of Drugless Practitioner. I joined the Renovare team in July, 2013.

I use EFT to help our clients with the 7th secret from Dr. Gerhart’s Book, – Detoxifying Your Body and Emotions. I enjoy the transformation and progress my clients make as they move from fear, depression and hopelessness into a more positive state of emotional wellbeing fueled with love, hope, and passion. Everyone deserves a happy life. Now is a great time to start!

I received my EFT training in Hong Kong followed by a 4 month internship at a Physical Therapy and Wellness Clinic in 2009. I trained with the founder of Matrix Reimprinting, Karl Dawson, from the UK. Matrix is an extension of EFT and provides an opportunity to rewrite a past trauma which allows for closure so that one can heal and move on.

EFT is an interactive energy healing modalities that can help you remove or lessen:

  • repetitive negative thoughts and memories,
  • chronic feelings of stress, anxiety, sadness, depression, anger, fear,
  • bad habits and addictions

EFT can help to resolve emotional, mental, and physical issues in a matter of minutes.

These sessions are highly effective for improving the following:

  • self-confidence
  • hope
  • love
  • respect
  • health
  • abundance

I am commitment to my profession with continued education to further increase my knowledge and skills. My technique allows me to quickly find the root cause and together releasing the trauma to heal emotional wounds. Emotional wounds left untreated become physical illnesses. Physical illnesses left untreated become disease.

You will feel results after one session of EFT. I will use a holistic approach because everything in life is connected. Balancing nutrition, physical activity, healthy thoughts, relationships, career/passion and fun to help you create the life you want. Live in the present and take action toward improving your health today. –
