Top Tutor on Wyzant: Business English, ESL, Operations & More
By Digby R. Kerr · Kerr University™ · All Articles
The first student I ever tutored on Wyzant was a logistics manager preparing for a job interview entirely in English — his third language. We had four sessions before the interview. He got the job, and he sent me a message afterward that I still have saved: "I didn't just pass the interview. I felt like myself in it."
That's the goal of every session I run, whether the subject is Business English, ESL, Operations Management, or Economics — and it's why, after hundreds of sessions, I've maintained Top Tutor™ status with verified five-star reviews on Wyzant.
What I Tutor
Business English & ESL — for professionals who already know the grammar and need fluency, confidence, and the specific vocabulary of their industry. We work on real meetings, real emails, real presentations.
Operations Management — drawing directly from thirty-five years inside FedEx, UPS, XPO, and CEVA. This isn't textbook theory. It's how operations actually run, with the trade-offs and pressures that case studies tend to leave out.
Economics — making the underlying logic intuitive, especially for students who've been taught the formulas without ever connecting them to how decisions get made in the real world.
Why It Works
I don't run a fixed curriculum. The first session is always a conversation about where you actually are and where you actually need to be — for a deadline, an exam, a job, or simply a long-standing gap you're ready to close.
From there, every session is built around what moves the needle fastest for you specifically. Some students need confidence more than knowledge. Some need vocabulary more than grammar. Some need someone to simply explain, in plain language, the thing their textbook explained in the most complicated way possible.
Try this: Before our first session, write down one specific situation you want to handle better — a meeting, an exam, an email, a conversation. We'll start there.
The bottom line: Whether you find me here on Kerr University or through Wyzant, the approach is the same — practical, direct, and built around the result you actually need.
