Independent Primary Care –

a Doctor-Recommended Solution


Nothing is more frustrating than not getting the care that you want from your healthcare team. Lack of options, long waits and high deductibles can make you feel like it’s easier to ignore your healthcare concerns than to address them. Having your concerns dismissed by your doctor or being forced to follow protocols you disagree with can make you feel like you’re not in control of your own healthcare.

What if you could work with your doctor to design a care plan that is tailored to your goals, see your doctor the same or next business day, and get through a visit without feeling rushed?

At Genesis Primary Care, we recognize the challenges our patients are facing with current healthcare models. We are taking a stand for our patients by delivering quality, patient-focused, cost effective care, without unnecessary tests, over-prescribing of medications or unneeded office visits. We eliminated everything you didn’t like about traditional healthcare and went back to the beginning.

Our Values

The best care comes from a direct relationship with your doctor

You and your doctor know what’s best for you. We get to know you as a patient and as a person and treat you without the interference of insurance companies or hospital administrators. You get highly personalized care, relaxed visits, and access to medical advice whenever you need it.

Staying healthy should be easy and affordable

Good healthcare = great quality of life. Forget expensive office visits, unnecessary tests, and confusing insurance forms. We give you almost unlimited access to your doctor – on your schedule, and put you in charge of your healthcare decisions. This means that you get the best healthcare possible – for less.

You deserve our undivided attention

You can’t accomplish much during the traditional 15 minute appointment… We do things differently. By limiting the number of subscribers and minimizing the time we spend on paperwork, we are able to focus on our patients.

You should get the care you need

Hoping a problem goes away is not healthcare. Yet, many patients are forced to take this approach due to the prohibitive cost of healthcare. By opening the door to unlimited visits, subscription-based cash-only primary care service promotes better health outcomes – and that’s exactly how we work at Genesis Primary Care.

Our Staff

David Lange, MD

 Dr. Lange became aware of his calling to be a physician at an early age. While attending the University of Minnesota, he spent his third year of medical school in Bemidji, MN participating in the University’s groundbreaking Rural Physician Associate Program (RPAP). There he found his ultimate calling to be a family physician in rural communities. He completed his residency at the University of Wisconsin-Fox Valley Residency Program in 1995. His first medical Practice was with Marshfield Clinic in Merrill, WI doing full spectrum family practice including obstetrics. Being very interested in technology in medicine, he transferred to the new Weston Clinic in 2005 when St. Clare’s Hospital opened up. During this time he helped out in Wittenberg, WI and was involved in the development and opening of their new clinic.

In 2010 he made the change to Ministry Health Care and worked in Stevens Point before returning to Wausau. He was Primary Care Medical Director with oversight responsibilities for all Primary Care Providers in Central Wisconsin. During this time he also helped out at several small Ministry Clinics while recruiting permanent providers for those locations. In 2020 he made his most recent practice change to Aspirus Medford Clinic.

Several years ago it became more difficult to be a corporate physician. Thus began his journey to private practice. You will see his philosophy throughout this website. He has 27 years of experience treating a wide variety of patients with nearly every medical condition. Listed on the website is an incomplete list of conditions that he manages. He is comfortable treating even complicated medical patients. While no longer doing OB he is still comfortable working with pregnant women for their non-OB healthcare needs. He also has a special interest in sleep apnea, being very comfortable in testing and managing.

The ongoing vision of becoming an independent physician to fully serve his patients has become reality through this endeavor.

Debbie S., RN

Debbie graduated as an RN in 2002. She spent her first ten years working in labor and delivery at St. Vincent Hospital in Green Bay. With moving out to the Wausau area, she started out in labor and delivery with Ministry Health Care at St. Clare’s Hospital. Then made a change to family practice at The Rib Mountain Clinic where she started working with Dr. Lange.

There has been a lot of changes over the past 10 years in Family Practice, with Ascension buying out Ministry and then Aspirus taking over Ascension.

I am excited for this next step in my life to be working with Dr. Lange at Genesis Primary Care. Family Practice has been so rewarding in assisting people of all ages.
