Steve Scheidler

As a youth, I attended a local Christian elementary school which closed the end of my 7th grade year due to lack of support from the local churches in the area that had been responsible for its covering and vision. Therefore, I spent my 8th-12th grade years in a public school.

I credit much of my foundational Christian principles to the years spent in Christian school and have fond memories of that experience. My siblings all went there and my family was always involved in the school activities. The school was like an extended family. Unfortunately, my local church had no vision for the school and was in a large part responsible for its demise. I believe that the church ultimately suffered because all of the young people (myself included) left the church, and many also left the Lord (myself included).

I was first introduced to Temple Christian (now Mannahouse Church) by my brother Bill who was an Elder at Bible Temple and had all of his 3 children in the school. My parents were still committed to Christian education and helped financially, as they were able, to make sure all of their grandchildren were given the opportunity to go to a Christian School.

My wife, Becky, and I got saved and started attending CBC (then Bible Temple) in 1980. When our 3 kids were old enough, there was never a question as to where they would attend school, Mannahouse Christian Acaedmey (formerly City Christian Schools).

Having seen first hand how the lack of financial support can doom a Christian school, my wife and I were determined that we would do all we could to help sustain the school.

Although we no longer have children in the school, our heart for Christian education has not changed. We are committed to help financially. Being able to serve on the board and contribute in that capacity, as well as financially, has been a great facility for us.

Miriam Trolese

Miriam has been on staff at Mannahouse since 2000 when she came to PBC from El Salvador. In 2002 she married Ben Trolese and their two greatest disciples and joys are David and Marissa, their two children, both of whom have been at CCS (MCA) since preschool. Miriam has been a pastor at Mannahouse for the last 15 years and an elder since 2017. She has traveled in the US and different countries to speak at women’s events. She is passionate to raise leaders to their full potential while building the local church.

Mike White

Michael White is President and co-owner of Gateway Communications Inc,in Portland, Oregon. Founded 1990, Gateway Communications provides marketing, printing, design and mail services to a number of Northwest corporations and non-profit organizations. White is also the Executive Director of the Oregon Family Council, an organization dedicated to helping Christian voters participate more effectively in voting and civic duties. The Oregon Family Council publishes the Christian Voter’s Guide which is distributed in over 1,800 Oregon Churches.

As a graduate of Portland Bible College and part-time instructor, White understands the importance and value of a quality Christian education. His two daughters have attended City Christian School (MCA) since first grade and he and his wife Willa have seen the remarkable fruit in their lives as a result. Mike and Willa have been married for 29 years and have three children. They serve as District Pastors at Mannahouse Church and Mike is an ordained Elder.

The Bible admonishes parents in Ephesians 6:4 to raise their children in the discipline and instruction of the Lord. Most of this scriptural admonition should be fulfilled in the home. But in a world where competing values and philosophies are in direct conflict with the Christian faith, it is a great comfort to have an option like Mannahouse Christian Academy to reinforce the Christian values and worldview that are essential to successful Christian living.

Why MCA?

What Others Are Saying About MCA!

Positive and Uplifting

I really like that the atmosphere is positive and uplifting and that there is a positive peer pressure.

One On One Time

I am thankful for the size of the school, because of the one on one time with the teachers.  At this school the teachers have time to help you out and they even know your name and care about you.

I love dropping them off everyday into the atmosphere and culture at Mannahouse Christian Academy.  I do not worry about them like I did at the public schools.  I know they are being attended to and that they are safe and secure.

Huge Progress!

My son has made huge progress during the last year.  In his character he has learned so much…. He wouldn’t have progressed as far as he has without the love, support, and mentoring he has received from the staff.

Generation of Leaders

Mannahouse Christian Academy is not only academically able to raise up the next generation of leaders, but also spiritually able to show a role model of Christ through the lives of the teachers and the staff.

Day Starts With Prayer

We love the fact that our children start the day with prayer and the fact that they are involved in chapel.  We can see a difference from the public school environment.

Most Profitable Investment

Over the last several years, my most profitable investment has been in Mannahouse Christian Academy. The benefits gained are immeasurable from a school that speaks, guides and teaches with the same foundation as our home.
