Colleen Tetzlaff draws from Western medicine and holistic treatment for individualized healthcare plans.Colleen S. Tetzlaff has been bringing together both the art and the science of conventional, Western medicine and holistic treatment since the early 1990’s. Her passion for holistic, healing health care began early in her career and grew out of the recognition that patients are best cared for when the practitioner recognizes the multiple influences on disease and wellness, including the physical, spiritual, and psychological influences. Her comprehensive individualized treatment plans are safe and effective, bringing together the best ideas and strategies which draw upon conventional and integrative science and wisdom.

She earned her Bachelor of Science in Nursing from the University of Maine in 1990, and her Master of Science in Nursing in 1997 and Doctor of Nursing Practice in 2012, both from Simmons College in Boston, MA.

From 1997- 2005, she worked in Vermont as a primary care provider, thus obtaining a firm grasp of wellness oriented care, as well as chronic disease management. Moving back to her native state in 2005, she worked for Maine Medical Center in the division of Gynecologic Oncology from 2006 to 2011. For several years now, she has dedicated her work with cancer patients to expertly guiding them in the integration of complementary therapies into their conventional treatment plan.  In 2011 she moved her integrative practice to Integrative Health Center of Maine in order to practice amongst and in collaboration with other integrative practitioners, recognizing that the best outcomes for patients come from a team-oriented approach to care. In 2012, she added primary care  to her services provided in order to more comprehensively help patients approach their healthcare utilizing the best ideas from natural and conventional medicine. She maintains certification in both oncology and family practice as a nurse practitioner. She has trained with Donald Yance, CN, RH (AHG), SFO in Ashland Oregon, one of the brightest minds in the field of integrative oncology and chronic disease management and founder of the Mederi Foundation. She is a member of the Institute for Functional Medicine, the Maine Nurse Practitioner Association, and the American Academy of Nurse Practitioners. She is also an Amen Clinic Affiliate.

Hi All,
I wanted to remind all of you that I am here to support you in anyway I can with your wellness goals.

It can be really frustrating and challenging to make all the dietary and lifestyle changes we suggest by yourself and we want you to get better and succeed!

Your symptoms and disease states don’t happen overnight. It takes patience and support to heal, as we work with you to discover what works and doesn’t work for your individual body and physiology.

Below is an update on how you can work with me. We will continue to offer an initial 60 minute office session with me and Colleen (covered by your insurance). After your first session- I am offering all of Colleen’s patients ongoing , 45 minute phone sessions that you would schedule with me (see info. below).

I will also be sending you a monthly newsletter with helpful wellness tips and updates to keep you informed and motivated.

We love supporting you all in creating a healthier, happier more joyful life!

MS CHC (Certified Integrative Health Coach)


Why DO I Need a Health Coach?

As your health coach, Mary is your wellness guide and supportive mentor.

Working with Mary Moskowitz MS CHC, our Integrative Health Coach, will give you a deeper understanding of the foods and lifestyle choices that work best for you.

She will guide you toward lasting changes that will improve your energy, balance and health.

It’s hard to do it alone!

Mary teaches the concept of bio-individuality which means that each person has her or his own food and lifestyle needs. So, when the experts say, “Dairy is good for you” or “Fat is unhealthy,” it doesn’t apply to everyone.

By embracing the principle of bio-individuality, she will support you in making positive changes that are based on your unique needs, lifestyle, personal preferences, and background. Mary believes that we are fed not only by food, but by other factors in our lives. Healthy relationships, a fulfilling career, regular physical activity and a spiritual practice are essential forms of nourishment.

Together we will explore balancing the primary foods in your life and supporting you towards lasting health and happiness.
