Serving New Mexico with compassionate estate and business planning.

Kenneth C. Leach and his associates have assisted families throughout New Mexico with estate planning, probate, real estate and business law since 1978. 


New Mexicans are special.

Those of us who call the Land of Enchantment home are highly entrepreneurial and often have small businesses or unusual assets. We have strong family ties. Our firm is deeply rooted in this state and we are attuned to the unique needs of the people here.

Our approach is one of respect and caring. Death can be quite devastating to families. The depth of our experience enables us to prepare our clients for this eventuality and guide them to outcomes that make financial sense, as well as sense for their family.
