"After many years in the field of technology, I acquired significant knowledge of mathematics and today I am motivated to share this knowledge with new generations.  While serving for more than 30 years in aeronautics, I studied BSEE Electronics and BSEE/MSEE Electrical Engineering (U.S Naval Postgraduate School, California) with a specialization in resource management.  During this time I developed a methodology that presents mathematics from a different perspective to achieve a precise understanding of its foundations, highlighting its importance and relevance in almost all aspects of daily life.  This methodology presents an integrated, problem-solving, research-based approach to mathematics while developing critical thinking.  As a tutor I seek to achieve understanding of the key elements beyond mere learning of routines and procedures.  Everything from what, when, how, why, usefulness or importance.  That is the mission that I always pursue...the understanding of mathematics...and that is my commitment.  With complete satisfaction, I have used this methodology called NTScL in the tutorials of Arithmetic, Algebra, Geometry, Calculus, Statistics, and in the preparation for standard tests.  In conclusion, being a tutor every day is a super interesting and motivating experience when you can achieve with complete certainty "doing mathematics based on your understanding."  Each session under the focus of a "Mathematics Clinic".  The bilingual (English and Spanish), In-Person (Home) or Online modality of my services that I offer to You for all these reasons says....." YOUR SUCCESS IN MATHEMATICS IS MY COMMITMENT!"" less...
