Michelle Kowalczyk
Founder, Managing Director

Michelle is a Nurse Practitioner in Hospital Medicine at Mayo Clinic. She is a Board Certified Acute Care Nurse Practitioner with a Masters in Nursing degree from the University of Nebraska Medical Center. She also received her BSN at UNMC. Michelle originally went to Tanzania in March 2007 to volunteer in a medical capacity, something she had always wanted to do. After arriving, she realized that her life was going to take a drastic turn as she found a new passion and meaning to her life. She does not know what is in store with her nursing career or how it will fit into her foundation work, but she feels so lucky to have found passion and purpose at such a young age and feels privileged to have co-founded and to have the opportunity to work for Knock Foundation.


Kim Krowne
Founder, Managing Director

Kim was born and raised in Northridge, California, a suburb of Los Angeles. She graduated magna cum laude from the University of Pennsylvania, having studied a pre-med curriculum and majored in Health & Societies with a concentration in African Health. She first traveled to Tanzania in November 2006 to work in a health clinic to help her in furtherance of a medical career. She did work in a clinic and loved the experience, but Kim also volunteered at a center for orphans and vulnerable children and through that, found a passion she didn’t know existed within her. For the following six years, she traveled back and forth between Tanzania and California, managing Knock’s projects, collaborating closely with local communities, working on the administrative aspects of the organization as well as fundraising efforts. Kim is currently studying at the School of International and Public Affairs at Columbia University towards a Master's Degree in Development Practice.


Barry Krowne
Founder, Director, Financial Advisor

Barry has been a practicing CPA for almost forty years, advising businesses and individuals alike, always looking to work with people who have solid life values and recognize that hard work and patience are essential to the achievement of success. He has traveled to Tanzania several times to see firsthand the needs and opportunities for the children and communities we serve and to provide assistance and oversight for our programs. He is committed to making a difference in the lives of the children we help to educate and feed. This is consistent with his life's work of being involved in causes and organizations to help "repair the world.” The resources of Barry’s office are being used to perform much of the Foundation's administrative and compliance work. In 2009 Barry climbed Mt. Kilimanjaro and returned in 2011 to climb Little Mt. Meru. Both climbs were very successful fund raising events and were part of his ongoing efforts as a major fund raiser for the Foundation.
