Functional Medicine Integrative Portland

About MHW

Merritt Health and Wellness is a unique family medical primary care clinic that blends traditional western medicine with an integrated eastern functional medicine approach.

MHW was founded by Seth Merritt in 2012. For the first couple years Seth saw his patients, built his own website, managed the phone calls and also did all the billing and collecting. By maintaining a low overhead and doing away with the traditional medical staffing model, Seth was able to give patients twice as long for their appointments. As more patients sought this unique care model, Seth eventually hired Ryan Merritt to do the billing and collecting as well as business management and patient interface.

Lindsey Wismer, NP was hired in 2014 followed by Thad Merritt for personal training. Kelly Washburn, NP and Dr. Kristine Griess began working in 2015. Dana Mozer, NP, Melissa Lynett-Federspiel, NP, and Claudia Dogan-Coles, PA were added in 2017.

We strive to keep our business model sleek with a low overhead and less support staff to provide longer patient appointments and more access to medical providers for our patients. Overall the patients that thrive in our clinic are the one’s that are open to a non-traditional model of patient care. We hope that you find that our clinic and providers meet your expectations and help you on your health journey.


In Functional Medicine we look for the causes of disease rather than just treating the symptoms. Functional Medicine revolves around our patient. Using DIG IN style to gather health history, we work as a team to hear your story. We attempt to fine the true cause of your illness. We can use state of the art lab tests and theory to help you achieve optimum health.

Dana Mozer (NP)Lindsey Wismer (NP)Melissa Lynett Federspiel (NP)Kelly Washburn (NP)and Dr. Kristine Griess all practice Functional Medicine at MHW.

Functional Medicine includes a nutrition plan, supplements, health coaching to get to the root of your issue. Functional Medicine will assess Food, Detox, Hormones, Energy, Cardio, Metabolic, and above all Gut Health. To learn more click here.

Many natural treatments can be hard to follow due to so many options. We match the treatment with the patient. We will meet the patient where they are. This helps the patient step to success rather than feeling overwhelmed with the treatment plan.


Western medicine might only use prescriptions to treat symptoms. Although, symptoms are only the tip of the iceberg when it comes to chronic disease. However, these meds don’t fix the problem, and they often they create other problems.

In functional medicine we take a different approach. Rather than covering up symptoms, we look for each person’s causes of inflammation and disease. We use the most up to date research.

Once we know your triggers, we remove the things that are causing strife in your body. We replace the things that your body is missing. We remove hidden infections, allergens, toxic chemicals, and foods that you are sensitive to. And, we replace digestive enzymes, vitamins and nutrients, and healthy bacteria. We also balance hormones and brain health.

In functional medicine we help find the real cause of disease, so that you can truly heal.


The illustration to the left uses a tree to visually represent the core aspects of the Functional Medicine paradigm and highlight the difference between conventional medical care and Functional Medicine. The graphic itself has undergone some changes through the years, but its essence remains the same. In order to keep a tree healthy and allow it to flourish, you need to support the most basic and essential elements first; the foundation: the roots and soil. Similarly, if a tree is not healthy, the first place you should look for answers is those same foundational elements.


The most important factors, and the ones we examine first when gathering information about the patient, are the foundational lifestyle factors; sleep, exercise, nutrition, stress levels, relationships, and genetics. These are the roots and soil, which are in turn influenced by specific predisposing factors (antecedents), discrete events (triggers), and ongoing physiological processes (mediators), and may then result in fundamental imbalances at the trunk. These can eventually result in the signs and symptoms that are grouped into a diagnosable constellation that we call disease, represented by the branches and leaves.

Conventional medicine tends to look at the constellation of symptoms first (the branches and leaves), which usually results in a disease diagnosis. Often, this diagnosis is associated with a drug or drugs that can be prescribed to treat this constellation of symptoms, and that is the end of the story. But this approach neglects the more fundamental aspects of health that reside in the roots and the trunk of the tree. It treats all patients that present with similar symptoms the same and completely neglects both the inherent differences among patients as well as the myriad possible causes that a “disease” can have.

If you are tired of spending your time in the leaves and watching as your patients with chronic disease go through the cycle of diagnosis and drugs without getting any better, IFM invites you to climb down from the canopy and join us at ground level. We will provide you with the tools to make your patients better, without ever needing to leave the ground.


A primary care provider (PCP) is a health care practitioner. PCPs see people that have common health problems. Also a primary care provider may be a doctor or a nurse practitioner. Also primary care providers are involved in health care for a long time. Hence, it is important to choose someone with whom you will work well.

A PCP is your main health care provider in non emergency situations. Hence, PCP’s role is to:

·         Provide preventive care and teach healthy lifestyle choices.

·         Also identify and treat common medical conditions.

·         And assess the urgency of your medical problems and direct you to the best place for that care.

·         And make referrals to medical specialists when necessary.

Also primary care is most often provided in an outpatient setting. Also PCPs assist in care with hospital admissions.
Hence, having a PCP can give you a trusting, ongoing care team with one provider over time.
We like doing primary care for our patients!


Staying healthy and living a long life starts with preventive healthcare. Also preventive healthcare can help you avoid illness. And detect problems before you notice any symptoms helping you stay healthy.

Preventive Care Guidelines includes info from the USPSTF. USPSTF includes an A rating (meaning a high chance of benefit to you is substantial). Also the Affordable Care Ace (ACA) covers a B rating (high chance of moderate benefit).

First of all, under the ACA new health plans since September 23, 2010 cover this preventive care.

Preventive care is practiced by our staff to keep patients healthy. Preventive health has a focus on the care of patients, neighbors, and defined cities. Its goal is to protect, promote, and maintain health. Also maintain well being and to prevent disease and death.

Nurse Practitioners are a health partner of choice for millions of patients. NPs are clinicians that blend knowledge in diagnosing and treating health issues. Also NPs focus on disease prevention and health management. NPs bring a comprehensive perspective to health care.

All NPs must complete a master’s degree program. And have clinical training beyond their nurse schooling. Clinical courses prepare nurses with knowledge to practice primary care, acute and long term health care settings.

If you’ve never been to a DO before, you may wonder what to expect. A typical office visit includes four parts: interview, exam, diagnosis, and treatment.

Interview: The DO will talk with you about your medical past. Also, you will be asked about such factors as your home, work, and family life.

Exam: Your DO will do a complete physical exam. Also, tests can be ordered.

Diagnosis: The DO will consider the results of your health past and exam and will tell you what may be causing your symptoms.

Treatment: The DO will suggest a treatment plan. This may include natural health and functional medicine treatments. Although in some cases it may include such options as drugs and surgery.
