Board of Trustees

The Board of Trustees is composed of five people elected by the voters of the hospital district for a three (3) year term. They are representatives from the areas of the district. The Board is responsible for seeing that the hospital is properly equipped, organized, managed and maintained to carry out the goals and objectives of the institution. All policies of the hospital are formulated by the board. All members of the medical staff are appointed by the Board upon recommendations from the medical staff.

The Board of Trustees are responsible to the donors, the community and the district to insure the permanence of the hospital and its services. They are vitally concerned with the finances of the hospital and are responsible for the establishment of a yearly budget.


In the spring of 1952, the economy of Rooks County was strong, with as many as 40 new homes built in a single year. The development of area oil fields and increased crop production provided a growing job market. With this growth came a concern for quality health care in the area.

A group of concerned citizens organized and circulated a petition asking for a vote on a County Hospital. Since the county-wide issue at that time was unsuccessful, it was decided to form a hospital district by petition. It was not an easy task, but volunteers from all areas of the district worked diligently to obtain the required signatures. Ralph and Geraldine Arnhold donated one square block of land in Plainville as a site for a hospital.

Early in 1953, the completed petitions were presented to the County Commissioners, thus forming Plainville Rural Hospital District #1. The first Board of Directors elected were businessmen Robert Burkholder and Oren Workman, and area farmers Johnie Dauwe, Harry Moos Jr., and Aaron Thomas. Harold Oelschlaeger, attorney and board secretary and Jewell Lewin, bank cashier and board treasurer. Townships in the original district were Richland, Northhampton, Fairview, Rush, Logan, Walton, Hobart, Plainville, Greenfield, Medicine, Twin Mound, Corning, Paradise, and the City of Plainville.

On February 21, 1955 the hospital doors opened to admit the first patients. Bill Brickley was the Administrator and Medical Technologist for 36 years. Dr. E. C. Petterson, the only physician serving this area prior to the hospital construction, helped recruit Dr. A .M. Pederson and Dr. Vale Page to the county.

On opening day, the medical staff consisted of Chief of Staff, Dr. Petterson, Dr. Pederson, Dr. Page and two dentists, Robert Andreson, D.D.S. and Arvin Rueger, D.D.S. A few months later, Harold Mauck, M.D., William Votapka, M.D., George Hopson, M.D., all of Stockton, joined the medical staff of the hospital. Dr. Petterson, Dr. Pederson, Dr. Page, Dr. Mauck and Dr. Votapka practiced medicine in this county until they retired. Their dedication and outstanding care will be remembered for generations.

In 1989, the Rooks County Commissioners voted to attach the following townships to the hospital district: Zurich City, Woodston City, Stockton City and the Townships of Lanark, Stockton, Farmington, Lowell, Ash Rock, Iowa and the Sarver’s addition to Stockton. The Board of Trustees voted to change the hospital’s name from Plainville Rural Hospital to Rooks County Health Center on January 1, 2003.

The Board hoped the name change would reflect on each community. With the name change, the Board incorporated a new logo for the hospital. The logo’s color blocks were selected to represent the school colors of Stockton (blue), Palco (yellow) and Plainville (red).

In April of 2003, the Board began the application process to secure financing for a new hospital to be sited just north of the City of Plainville. In 2006, an overwhelming majority of the voters of the RHC Hospital District gave their approval to the Hospital Board to begin construction on the new facility. Construction began in 2007 and the Rooks County Health Center officially opened on September 22, 2008. The hospital has an effective area of service of nearly 1,300 square miles and an effective service population of over 8,000 citizens of northwest Kansas.

Our current medical staff consists of Dan Sanchez, M.D., Beth Oller, M.D., Mike Oller, M.D., Ron Williams, APRN, Emily Decker, PA-C, Jerome Molstad, PA-C, Leann Zimmerman, APRN, Mary Takaishi, PA-C, and Cheyenne Armbruster-Wahrman, PA-C.  Our rich history has provided the foundation for a hospital that has become the benchmark against which all other rural Kansas hospitals are measured. Rooks County Health Center has been serving this area of Northwest Kansas since 1955.

Cheyenne Armbruster-Wahrman, PA-C

Specialty: Family Medicine


Cheyenne Armbruster-Wahrman grew up in Plainville and graduated from Plainville High School in 2013. She chose primary care because she enjoys seeing a wide variety of health conditions and age ranges. Armbuster-Wahrman’s philosophy is to always make her patients feel comfortable talking to her and to ensure they know she is there to listen to their health concerns.

She loves the close relationships that small-town living fosters, and Plainville’s close-knit community spirit is evident in the way everyone rallies together to help those in need.

In her free time, she enjoys relaxing with her family and friends. She recommends RCH as a workplace to fellow Primary Care Providers because of the opportunity to get to know patients inside and outside the clinic, as well as the supportive environment among providers, especially for those new to the profession.

Mary Takaishi, PA-C

Specialty: Family Medicine


Mary C. Takaishi, PA-C, chose to pursue primary care after her family experienced her sister’s premature birth, which involved numerous hospital and doctor visits. Despite initially aspiring to be an astronaut, her dream shifted after a touching encounter with an elderly man with Parkinson’s Disease during a college Christmas caroling event. This encounter ignited her desire to pursue a medical career, leading her to attend PA school to provide care and support to those in need.

Takaishi’s approach to patient care is characterized by compassion and empathy. She strives to create a welcoming environment where patients feel at ease discussing their health concerns. Beyond the clinic, she actively engages in community services, volunteer work, and public health initiatives.

Originally from Olathe, KS, Takaishi practiced medicine in South Central Kansas before settling in Rooks County with her wife. She prefers the rural setting for raising her daughter over a metropolitan area. On weekends, she enjoys spending time with her daughter and tending to her own self-proclaimed “funny farm”.

During medical training, I liked a bit of everything I did and Family Medicine became a very logical choice.  To follow a patient over many years, often treating generations of the same family, gives many insights into a person’s make-up–physically, mentally, emotionally and spiritually. 

I once asked a friend’s dad who was a general practitioner (the term used in that day) what his favorite part of medicine was and he told me preventative medicine.  I asked him what that meant and he said it was about helping people become and stay healthy so they wouldn’t get sick.  “Boring!” I thought.  I wanted to save lives, remove disease and do heroic things.

Now I understand.  We can really abuse our health and then bring our broken bodies for a doctor to try and heal, but how much better to take care of it in the first place and maintain it in good working order.  I understand my mentor’s line of thinking. 

My medical school’s motto is, “To Make Man Whole”.  That is my deepest desire, to restore the whole person to his or her greatest potential and maintain the highest quality of life possible.
