About Functional Medicine Physician Christine Maren, D.O., IFMCP

Christine Maren D.O. is a board-certified physician and the founder of a virtual functional medicine practice in Colorado, Michigan and Texas. She was introduced to functional medicine after struggling with pregnancy complications and recurrent miscarriages. Now a mother of three, she’s devoted her professional life to helping others address the root cause of symptoms in order to restore health, prevent disease, and get their life back.

She earned her medical degree (D.O.) at the Chicago College of Osteopathic Medicine of Midwestern University and later moved to San Antonio, Texas to train at one of the nation’s premier family medicine residency programs at CHRISTUS Santa Rosa Hospital.

Part of Dr. Maren’s residency was spent in Tucson, Arizona, studying with Dr. Andrew Weil’s group at The University of Arizona Center for Integrative Medicine. Dr. Weil, also known as ‘The Father of Integrative Medicine,’ was a guiding figure early in her career.

She was later introduced to functional medicine to address her own health concerns, and knew it would become the focus of her practice. Inspired by 2X NYT best-selling author and fellow functional medicine physician, Dr. Amy Myers, she joined her practice at Austin UltraHealth. She completed her exams and coursework to become a Certified Practitioner with the Institute for Functional Medicine (IFMCP) in 2017.

Dr. Maren opened her own independent practice upon relocating to Metro Detroit for her husband’s fellowship training, and later returned home to Colorado to be closer to family. Dr. Maren is able to offer patients her unique brand of functional medicine care with a focus on women’s health concerns such as hypothyroidism, Hashimoto’s, gut health, autoimmune disorders, fertility challenges, and hormonal issues.

About Functional Medicine Nurse Practitioner Carolyn Teague, MSN, RN, FNP-BC, IFMCP

Carolyn Teague comes to us with over 20 years experience in conventional and functional medicine. As a nurse, Carolyn worked in a variety of specialties including the emergency room, trauma, labor and delivery, family medicine, and chronic disease management. It was through this hands-on experience she witnessed the necessities and limitations of an orthodox medical approach.

However, it was her 10-month old daughter’s mysterious body odor (!) that led her to explore alternatives in functional medicine. From there, she was inspired to find the real “why” behind her own symptoms, which included a multiple sclerosis diagnosis that led to some pretty scary and unnecessary interventions.

From there, she turned to her friend and colleague… Dr. Maren and Carolyn met many years ago when Carolyn was on staff during Dr. Maren’s Family Medicine Residency Program. Carolyn eventually became a patient in Dr. Maren’s functional medicine practice and found the answers she needed to defy her diagnosis, regain her health, heal her daughter, and achieve true peace of mind (the cause of both their ailments was mold by the way).

Blown away by her own reversal of disease, she was determined to help others do the same. Thereafter, she completed the Institute for Functional Medicine’s Practitioner Certification Program (IFMCP) and dedicated her practice to integrative functional medicine care.

Carolyn joined Dr. Maren’s practice in 2021 as a Functional Medicine Nurse Practitioner. Her ultimate goal in serving patients is to help them find peace of mind in knowing the cause and hope in the possibilities for lifelong health. Read more →

About Functional Medicine Holistic Nutritionist Jessica Doyle CNTP, RN

Jessica Doyle is a Certified Nutritional Therapy Practitioner (CNTP) and Registered Nurse (RN). She is also a certified health coach for preconception, pregnancy, and postpartum. With over 20 years working in the healthcare industry, Jessica specializes in supporting her patients through tailored nutrition with the goal of experiencing more vitality, wellness and energy.

After ten years working as a labor and delivery nurse, along with experiencing her own health issues, she realized traditional western models of medicine couldn’t provide the solutions most people needed to resolve their health issues. She realized that some patients felt dismissed and frustrated with “normal” test results despite abnormal symptoms, which persisted and often developed into more serious health concerns.

Always a learner and never satisfied with the status quo, Jessica decided to explore other avenues of healthcare and found Functional Medicine.

She attended the Nutritional Therapy Institute of Denver for two years to become a CNTP. She also trained with the Institute for Functional Medicine (IFM), and attended numerous Apex courses designed by Dr. Datis Kharazian. Most recently, she completed a health coaching certification for preconception, pregnancy and postpartum, and she is currently enrolled in a sports and performance nutrition program which uses a holistic approach to maximizes the body’s natural ability to achieve personal fitness and athletic goals.

Jessica joined Dr. Maren’s practice in 2020 and enjoys consulting one-on-one with patients on fertility, pregnancy, gut health, autoimmunity and metabolic conditions. She also provides nutritional education for weight loss, anti-aging, aesthetics and sports performance. Read more →

About Samantha Shoemaker, Patient Coordinator and Office Manager

Samantha began her career in the health field studying physical therapy, which led her to her true passion as a yoga instructor. However, it was after getting to know Dr. Maren during her family’s time in Michigan that she discovered functional medicine. And (as she puts it): “my life was forever changed.”

Samantha received a yoga instructor certification from Beaumont’s School of Yoga Therapy, and has been teaching corporate, private, and group classes since 2014. Her practice ran the gamut from offering truck driver’s yoga to working in the Karmanos Cancer Institute in Detroit. This experience running her own practice and as a caregiver, along with her passion for healthy living makes her ideally suited for her role as office manager and patient coordinator.

Samantha takes care of all our administrative work (and then some!) while helping coordinate efforts between our team, new and established patients, vendors, labs, contractors, etc. She loves her job, and excels at keeping everything running smoothly behind the scenes while creating a welcoming environment for our patients.

For Samantha, working within this field is deeply personal as a close family member was a victim of the opioid epidemic and she has also watched many other people in her life struggle with their health while never being guided to treat the root cause of their complaints. Thus, she has become a tireless advocate for helping others finding better routes for healing and care through integrative functional medicine.

In her spare time she is likely practicing or teaching yoga, hiking with her dog and husband, exploring nature, spending time in Northern Michigan… Read more →

About Leah Novak, RN, BSN

Leah Novak is a Registered Nurse (RN, BSN), personal trainer (CPT) and Master Nutrition Therapist (MNT). She has been working in the health care and fitness industry for over 20 years. Leah spends most of her time supporting Dr. Maren in a nursing role, working hard behind the scenes to ensure her patients are provided with seamless care. 

Leah’s career started in the Intensive Care Unit, Chemical Addiction/Rehab, and Operating Room at various local hospitals. In 2015 her own health issues led her to functional medicine where, as a patient herself, she learned that conventional medicine practices weren’t providing the healing she desired. Within 12 months of using a functional medicine approach, Leah’s health improved immensely. So much so, she made a career change to be part of the medicine specialty that better aligned with her values.  

She started working for Dr. Maren in January 2019 and hasn’t looked back since! Shortly after joining Dr. Maren’s practice, Leah felt the need to further expand her knowledge of evidence-based nutritional therapies. Therefore, she enrolled in a holistic nutrition therapy program to become a certified Master Nutrition Therapist. She is detail-oriented, a team player, and a true advocate for her patients.

Outside of work, Leah is a wife, a mother of two, an Orangetheory Fitness Coach, and a group fitness instructor. If she’s not reading about nutrition or listening to functional medicine podcasts, you will find her playing outside in beautiful Colorado, running her kids to their various activities, playing cards with her husband, walking her dog, or catching up with friends… Read more →
