Our History

West Michigan Nephrology

West Michigan Nephrology

 Western Michigan Nephrology (WMN) began in the early 1970s when Dr. David McBeth established a renal program at Mercy Hospital’s newly relocated campus. The practice expanded with the additions of Dr. Sally Hood and Dr. Barry Kram in the early 1980s, followed by Dr. Downer in 1987, who joined to help manage Mercy’s 12-station unit serving roughly 30 dialysis patients out of a small campus office. Following Dr. Hood’s departure in 1989 and Dr. Twu’s arrival around 1990, WMN entered a key growth period when Gambro constructed Muskegon’s first freestanding outpatient hemodialysis center directly on Mercy Drive, laying the groundwork for expanded regional care.

Frequently Asked Questions

A Nephrologist is a physician who specializes in diagnosing and treating diseases of the kidneys, as well as conditions that affect kidney health, including high blood pressure (hypertension).

If you have been diagnosed with kidney disease, seeing a Nephrologist early can make a significant difference. Early evaluation and treatment can help slow the progression of kidney disease, preserve kidney function, and reduce the risk of complications.


Your kidneys are essential organs that help keep your body in balance. They filter waste products and excess fluid from your blood, which are then removed from the body through urine.

In addition to filtering waste, your kidneys help regulate important functions such as fluid levels and

electrolyte balance (including sodium, potassium, and calcium). They also produce hormones that help control blood pressure, stimulate the production of red blood cells, and support bone health.


CKD stands for Chronic Kidney Disease. It is a condition in which the kidneys have been damaged or are not functioning normally for at least three months or longer. Chronic Kidney Disease is classified into stages based on a lab value called the GFR (glomerular filtration rate), which measures how well the kidneys are filtering blood.


  • Stage 1: GFR ≥ 90 (normal or high kidney function with signs of kidney damage)
  • Stage 2: GFR 60–89 (mild decrease in kidney function)
  • Stage 3: GFR 30–59 (moderate decrease in kidney function)
  • Stage 4: GFR 15–29 (severe decrease in kidney function)
  • Stage 5: GFR < 15 (kidney failure)

Early detection and management of CKD are important to help slow progression and protect kidney function.


No. Many people with kidney disease never need dialysis. While some cases can progress to kidney failure, early diagnosis, regular monitoring, and proper treatment can often slow the progression of the disease and help preserve kidney function for years. Our goal is to provide personalized care that helps keep your kidneys as healthy as possible.
