Osiemo Wanyonyi & Co. Advocates is a full-service law firm offering comprehensive, practical, and results- oriented legal solutions to individuals, corporates, institutions, and public entities in Kenya and across the region. The firm is founded on the principles of professionalism, integrity, accountability, and client-centred service delivery. Since its establishment, the firm has steadily grown into a respected medium-sized practice capable of handling complex, high-value, and sensitive legal matters.
The firm was incorporated in 2018 following the dissolution of the former firm of Kiplagat, Kiptoon, and Osiemo Advocates, building on the legacy, experience, and professional networks developed under that practice.
Today, Osiemo Wanyonyi & Co. Advocates continues to expand its footprint while maintaining a personalised approach to legal representation.
