William Brubaker

GRE & GMAT Expert With 11 Years of Full-Time Tutoring Experience

Meet William Brubaker:

GRE & GMAT Specialist.

With over 11 years of experience as a full-time GRE and GMAT tutor, I have honed my skills in providing comprehensive and effective support to help my students achieve their GRE and GMAT score improvement goals. My dedication to optimizing the GRE and GMAT tutoring experience has resulted in the successful development of a structured system, and my students have consistently reported high levels of satisfaction with my patient and well-prepared approach to the GRE and GMAT.

In addition to my GRE and GMAT tutoring expertise, I bring a well-rounded background to the table. I hold degrees in Architecture and Business Administration from the University of California at Berkeley, and have gained valuable experience as a project manager for major commercial real estate developments in cities across the United States, as well as in Abu Dhabi and Hong Kong.

As a father of three children, I balance my passion for education, specifically in the GRE and GMAT, with my family commitments, and currently reside in the beautiful Sierra Nevada Mountains in California.

Services: GRE & GMAT

Hourly Rate: $175 – We design a customized learning plan for each student to meet their individual needs and goals. Our comprehensive GRE prep program, on average, involves 10-15 hours of one-on-one tutoring with William, but students should also plan for self-study and additional homework outside of their sessions. Similarly, a comprehensive GMAT prep program typically requires 15-20 hours of tutoring with William, in addition to self-directed study.
