Welcome to SDII!
We provide affordable, durable, and sustainable technology solutions that will support Liberia’s economic growth through agriculture and renewable energy.


Sustainable Development International, Inc. (SDII) is a for profit corporation focused on Project/Program Management to meet the triple bottom line benchmarks of sustainable development. All projects are planned, designed, managed, controlled, monitored, maintained, and assessed for continuous improvement to be economically profitable, create new fair-wage jobs using new technologies, and be environmentally healthy with social equity. The corporation has modeled an entrepreneurial food enterprise system to improve food security, energy poverty, and water management in under-developed countries. A new self-reliant and entrepreneurial generation of farmers will be trained at knowledge-based demonstration sites to grow and add value to nutrient rich foods to build healthy urban and rural communities. Promoting “green technology” to build “green horizontal and vertical infrastructures” using natural and renewable resources to positively impact a new “green economy” that improves the quality of life of people and communities is the mantra of SDII.

SDII’s mission is to implement this decentralized approach to development through the participation of stakeholders (subsistence farmers, smallholders, NGOs, government, aid agencies, and international partners) that will provide food security, energy, water, and technology in order to improve the economic and physical health of communities while prioritizing the triple bottom line.

He has a strong background in program & project management, risk analysis and management, performance analysis, healthcare financial planning and analysis, strategic planning, healthcare regulatory trends and development, and healthcare underwriting.

His unique ability to recognize business objectives, foresee the solutions, and develop approaches, estimate resource and support the completion of projects on-time and within a budget is a strong asset to SDII.
