VouchExpert Panel
The coaches behind the numbers.
Each profile pairs credentials and methodology with real student testimony. Filter by the level that matches your situation.
Margaret Osei-Bonsu
M.Ed. Curriculum & Instruction, Boston University
SAT/ACT Prep · College Application Essays · Study Systems
Methodology
Margaret starts every engagement with a diagnostic audit — not just of test scores, but of the student's actual study habits and sleep schedule. She builds custom "exam blueprints" that map each student's error patterns to targeted drill sets, then revisits every two weeks.
Student Outcomes — 3 selected
"I went from 1180 to 1410. My mom cried. Margaret made me track every wrong answer in a spreadsheet — I hated it at first, then I got it."
Diana Kowalczyk
Junior, Chicago IL — SAT prep, 8 weeks
"She read my first draft and said "this sounds like a brochure, not a person." Three rewrites later I got into UT Honors."
Tomás Reyes-Aguirre
Senior, Austin TX — college essay coaching
"Went from a 2.6 to a 3.5 in one semester. The weekly check-ins kept me accountable when nothing else did."
Priya Chandrasekaran
Sophomore, Fremont CA — GPA recovery
Average SAT improvement across Margaret's high-school clients
Dr. Jerome Whitfield
Ph.D. Educational Psychology, University of Michigan
Academic Recovery · ADHD Coaching · Semester Turnarounds
Methodology
Jerome works exclusively with undergraduates on academic probation or scholarship warning. His intake process involves a frank 90-minute conversation about what went wrong — no judgment, just forensics. He then builds a semester-long recovery map with weekly check-ins and explicit "exit criteria" so students know exactly what success looks like.
Student Outcomes — 3 selected
"I was three-tenths of a GPA point from losing my scholarship. Jerome mapped out exactly which five assignments would move the needle. I kept it. Barely. But I kept it."
Marcus Okafor
Junior, Ohio State — scholarship warning, Spring 2024
"First time anyone actually explained the difference between being behind and being lost. I was behind. That reframe changed everything."
Sofia Hernández-Vega
Sophomore, UCLA — academic probation
"He didn't give me a planner. He gave me a system that worked with how my brain actually moves. Passed all four finals."
Ben Nakamura
Senior, UW-Madison — ADHD + finals crunch
Average GPA increase for undergraduate recovery clients in one semester
Dr. Ananya Krishnamurthy
Ph.D. Cognitive Science, Stanford University
Thesis Completion · Dissertation Coaching · Research Writing
Methodology
Ananya's clients are graduate students stuck in the final stretch — ABD candidates, thesis writers, and researchers who can't finish. She uses structured "chapter sprints" with hard weekly word-count commitments and a writing accountability partner system she built over a decade of working with doctoral candidates across disciplines.
Student Outcomes — 3 selected
"I had been ABD for four years and genuinely thought I would never finish. Ananya broke my dissertation into 11-day sprints. I defended eight months later."
Rachel Goldstein
Ph.D. candidate, Columbia — 4 years ABD
"She asked me one question: "What does done look like?" I couldn't answer it. That was the problem. Six weeks later I could, and I did."
James Osei
Master's student, Georgetown — thesis stall
"Three journal rejections had broken my confidence. Ananya treated them like data. Revised, resubmitted, accepted."
Mei-Ling Zhao
Ph.D. student, UT Austin — research writing block
