Work With Us

When you choose to work with us on your health recovery journey, you have the benefit of 2 minds, 2 perspectives, twice the strategies, and twice as much knowledge!

Our backgrounds…

Dr. Colleen Trombley-VanHoogstraat, D.C., B.H.K.: Undergraduate studies in Human Kinetics, Applied Kinesiology, Exercise Physiology, and teaching. University of Windsor and Queens University

Dr. Marc VanHoogstraat, D.C.,B.Sc.: Undergraduate studies in Science ~ Biology & Physiology. Southwestern Missouri State University

We both have post-graduate studies in Advanced Nutrition & Nutrition testing, Epigenetics and the Science of the Wellness Lifestyle (Wellness Certification program), Functional Physiology & “Medicine”, Integrative Cancer Recovery, and much more. We have 19 years of hands-on clinical experience in the Wellness Practice we share in Oxford, Michigan.

We have personalized “Distance Care” programs to help you regain your health, regardless of your geographical location.

We currently offer Investigative & Functional Health Recovery Programs for the following health conditions and concerns:

Autoimmune conditions

“Leaky Gut” / Intestinal Permeability

Food Sensitivities

Gluten Sensitivity & Cross Reactivity

Thyroid Imbalance

Weight Loss Resistance

Hormonal Imbalance

Fertility Issues

Lyme’s Disease

Cellular Detoxification

and General Nutritional ‘Coaching’ / Cellular Healing Diet


We refer to our work as “investigative” in nature since we work with each individual in order to properly assess the true cause of their health imbalances. There is no cookie cutter!

During your initial consultation, we will review the results of your preliminary assessments and possibly recommend advanced functional laboratory testing at that time… or not. These are not just any lab tests or laboratories we work with. The labs we choose for our testing are considered the best, most cutting-edge available anywhere in the country. Your health is worth it.

Together, we decide the best “next steps” for YOU, dependent upon the condition of your health, your health goals, your desire to improve, your budget, and your time restrictions.

Some people just want to a consultation to hear what we would recommend.

Others want a multi-phase full health recovery protocol.

Most of our programs are from 1 month to 12 months long.


The first step is to schedule your consultation.


We can do this by phone, by FaceTime, or by Skype. (Obviously, if you’re “local”, you are more than welcome to visit our practice for your consultation.)

In preparation for your consultation, we will send you your Metabolic Assessment, Neurotoxic Assessment, and Lifestyle Evaluation. If you have any recent lab work, please plan on sending those results to us prior to your consultation, as well. We do our homework before your consultation. By the time we speak, we aim to know as much as possible about your health… and what’s preventing you from feeling (& functioning) your best.

The intention of your consultation is to give you the right action steps and plan to move forward with your health from that point. Sometimes, a treatment & recovery protocol is recommended at that time. Sometimes, further testing is required in order to determine the best course of action to take next. Again, no cookie cutters!

This initial consultation is usually 45-60 minutes. The fee is $195.

We do provide a discounted fee for additional immediate family members.

We look forward to *meeting you* soon!

Here’s what others on our care programs have said…


“At first, I felt completely overwhelmed… but Dr. Marc and Dr. Colleen helped me take it one step and one day at a time. When I had questions or concerns, the doctors patiently worked with me… they were always in my corner cheering me on, whether it was for my healing diet, exercise or weight loss. This is exactly what I needed. I know I could not do this without these knowledgeable, caring people guiding me!” ~ Diana

“Last month my cholesterol numbers were much better and I no longer need to take any blood pressure medication! Working with Drs. Marc & Colleen has been a life changing decision for me!” ~ D

“Dr. Marc & Dr. Colleen have a true passion for what they do, and what they do is never less than outstanding. It’s evident that they’re committed to doing what’s right and will not settle for taking the path of least resistance.”  ~ Harold


“In the years that we have been part of their practice, Dr. Marc & Dr. Colleen have guided us with all of our health and wellness needs. These doctors have not only helped us with our health issues and questions, but have given us a wealth of health and wellness information that have totally changed the way we live…our physical activity, our food choices, and really the way we approach our lives and view our lives.  All of these changes have been for the positive and we can’t thank them enough!

Over the years we have referred many, many families and individuals to their practice, and all of those have thanked us for the positive changes that have happened in their lives as well.

One of the things that I love most about them is that they don’t just recommend something and then leave you to sink or swim all on your own. They are there to answer questions, provide support, and lovingly guide you to the next step. They live in the real world and know the challenges that we face, but still encourage us to just take baby steps, because each little improvement we make, makes for a better quality of health and life. 

There isn’t anyone that I’ve come across that is more highly educated with practical information to change lives than these two. And what I really love is that if they don’t have an answer to a particular question, they will find the answer. Love that!

In short, they have become our trusted health and wellness professionals. We can’t recommend them highly enough to anyone interested in taking steps toward a healthier, happier life.” ~ K.D.
