Rainer & Kerstin Knaack started off as Marriage Mentors in 2008, founded RelateWorks® in 2012 and have been sharing responsibilities as CEOs since.
They combine their training skills and experiences with the passion for ministering to couples and families. Their desire is to train leaders, pastors, counselors and lay couples to be effective Marriage Mentors. Personally, they have been mentoring different types of couples and individual personalities in most seasons of life, both locally and globally.
Leading their own marriage since 2005, Rainer and Kerstin have walked through different challenges - including four miscarriages and their stillborn daughter 'Loah' in the ninth month of pregnancy.
They know firsthand how a couple's marriage journey can be filled with both profound joy and sadness. Out of their experiences flows a genuine compassion for couples facing life's challenges in many forms. God's transforming work in their lives led them to step out of their professional careers in 2012 and into their calling.
After six years at Siemens Healthcare, Rainer fully committed his life to strengthening marriages, families and relationships by establishing an international marriage mentor ministry. Rainer holds two degrees, one in Business from the University of Cooperative Education and one in Design from the University of Arts in Berlin (UdK). His second thesis, "Decisive Leadership by Tacit Knowledge" was published as a book after he finished his research at Edith Cowan University in Perth, Australia (ECU).
Kerstin first studied 'Performing Arts' in Berlin and graduated with a degree in Business Administration and Languages. Following her studies, she combined her backgrounds of acting and business by working in a Business Theatre Company. After that, she joined an international company, headed a team of seven internal and 200 external employees in Human Resources and trained other trainers. Kerstin is certified as a Business-Trainer BDVT and DISC®-Trainer.
Rainer and Kerstin are certified by Life Innovations® as Prepare/Enrich® facilitators. They are leading the development of the German translation of the breakthrough book "The Solution for Marriages: Mentoring a New Generation", published since spring 2013 entitled as “Die Lösung für Ehen - der Weg zu einer neuen Generation von Ehen”.
Since May 2013, Rainer & Kerstin are privileged to call themselves parents of their son Noah.
In April 2015, their 'sixth' child, daughter Anna, was entrusted with their family.
In 2019, there was supposed to be 'Leo' joining their family as another miracle...
