Jim Weisert

Jim Weisert


Jim Weisert spent the majority of his career in Sales and Marketing, having served as Product Line Manager, Regional Sales Manager, Director of Sales and Marketing, and Vice President of Marketing and Commercial Development in the Semiconductor Laser industry and Directed Energy Weapons industry. Jim worked for several corporations, including Opto Power, Spectra Physics, Lasertel, and Ionatron.

Jim’s passion for building God’s Kingdom has been growing since he gave his life to the Lord at age 28. Prior to that time Jim had turned away from the Lord for the better part of twenty years. The change occurred after having read a book by Ann Rand (a self-professed atheist), and then receiving a challenge from a fellow employee to read the four Gospels of the New Testament. The conflicting views quickly took Jim on a journey to seek out more and more information on who Jesus was, and if he was real. All the while, his faithful Christian wife, Beth, patiently continued loving him to Jesus until the day he joyfully gave his life to the Lord.

Jim retired from the corporate world a few years ago. Now instead of building Jim’s kingdom to create wealth for himself and his family, Jim is focusing on building God’s Kingdom and sharing the Good News with others. In 2008, Jim was chosen to be an elder at Pantano Christian Church in Tucson, AZ. He serves on multiple committees, three other non-profit Christian boards, as well as serving on the board of Unite 4 Africa.

“It is more blessed to give than to receive” -ACTS 20:35

I started my working career at McDonalds on Broadway across from Park Mall where I met my beautiful bride Barbara of more than 28 years.

Later I spent 7 years working with my father at Snoopy’s Flight school teaching hundreds of people to fly small airplanes. During these years I discovered my love for teaching as well as the benefits and heartaches of owning a small business. After working many evenings and every holiday, Barb and I decided it was time to find a career where I could be home to help raise the children.

I started in the financial services industry in April of 1993 with Prudential Insurance. My last year at Prudential! was ranked 59th out of more than 10,000 insurance agents. I decided after 7 years working at Prudential to join Paine Webber, which later bought UBS and changed my focus to more securities related work. I was ranked number 1in my Training class. During this time at UBS I recalled the advantages of owning a small business and decided to start one in 2005.

Being in a small business can be truly challenging yet immensely satisfying. GR Financial has allowed me to work with truly incredible people. We are not driven by some mandate on high and can happily help clients every day. After turning 50, I realized that I am having more fun today than I have ever had. I believe that if I continue to work with such caring people and clients that I am proud to call friends that this journey will continue to be incredible.

I look forward to many more years of educating and “giving” to the incredible clients we have been blessed to serve.

It’s a honor to serve in Board of Unite 4 Africa and become a part of Empowerment and real change that start from within a person, a community that bring abundant life in Christ.

Samson Abukari

Samson Abukari

West Africa Director

Samson hails from Moglaa a small farming community in the Savelugu/Nanton Municipality in Northern Ghana. Samson is a Teacher by Profession and currently a Community Development Practitioner. His teaching career took him to the Tarikpaa community where he thought for three years before moving to college. From college he taught at the Northern School of Business Senior High School until the latter part of 2005 when he moved into community development work.

He began his community development work at the Tuma Kavi Development Association a local NGO in 2005 and worked until 2008 when he moved to the State of Texas in the United States of America for a year’s internship program in sustainable agriculture, community development and Christian Missions. When he returned to Ghana in 2009 there was no vacancy for him at his former organization. After staying at home for a number of months, he was contacted by Creating Change Organization to come and assist in offering leadership for the organization. His service at Creating Change enabled him to touch over 1000 lives directly and several thousands of people indirectly. One of the staff testified saying “you have fulfilled the mission the Lord brought you to Creating Change to accomplish, for you have helped me to draw closer to God”

Born to Christian parents from a Moslem background, Samson saw the need to draw closer to God at a very tender age and was following his father to a different village where he was a Lay Leader for the Church in that community. Samson’s faith was based on works until he got born again at the senior high school. After accepting Christ he served extensively as a student Christian leader in any institution of learning that he found himself. This lead him to serve as organizing secretary for the Scripture Union (SU) and Ghana Fellowship of Evangelical Students (GHAFES) non-denominational Christian bodies for students.

In August 2012 Samson was ordained as a Deacon in his Church. He has served as the National organizing secretary and National Secretary of the Ghana Baptist Convention Youth Department. He was elected the President of the Ghana International Baptist Convention in 2009 and was re-elected for another term in 2014.

Samson’s passion is to see humility and truth exhibited in servant leadership as he serves God through service to humanity. His desire is to see believers experience real transformation which will then positively affect their communities. To him every person is affected by what they put into their bodies and minds thus, physical food and the words that they feed their thoughts with. It is as a result of this that he led the formation of an organization known as Watch What You Eat Foundation to trigger some form of sustainability and wealth creation among people that come into contact with him,.

Samson got into contact with Unite 4 Africa in 2007. He has since served in different capacities until his elevation in September 2013 as the Country Director of Ghana. He is happily married to Salomey and their marriage is blessed with three children; Jesse Wunyurilim (God’s Love), Geraldine Wuntiti (God has given us) and Gerald Wunimmi (God knows).
