Business Communication & Negotiation Coaching
Say it like you mean business.
I coach client-facing tech and sales professionals to negotiate, present, and close in English with real confidence — live, one-to-one, over video, from a timezone that actually overlaps with yours.
Before → After, in one client call
I think maybe we can to discuss about the price, if is possible for you.
↓ same meeting, five weeks in
I'd like to discuss pricing — is that possible on your end?
Hours that overlap
South Africa's timezone sits almost exactly on Central European time — live sessions during normal EU business hours, no early mornings or midnight calls.
Built on real sales experience
Coaching shaped by an actual B2B sales and account-management career, not a generalist ESL curriculum.
Real-time, not recorded
Every session is live video coaching, adapted to what came up in your last client call — not a fixed video course.
Built for L&D, not just individuals
Programs designed to be commissioned by a company for a team, with outcomes an L&D sponsor can point to.
Programs
Two ways to work together
Individual
1:1 Coaching
For sales engineers, account managers, and client-facing professionals who need to sound as capable in English as they are in their own language.
- Weekly live video sessions
- Curriculum built around your real calls, emails, and deals
- Direct feedback on negotiation and presentation language
Corporate
Team Programs
For L&D and Talent Development teams investing in client-facing communication across a cohort, not just one hire.
- Cohorts of 4–6 professionals, run in quarterly cycles
- Cross-cultural sales communication curriculum
- Progress reporting an L&D sponsor can share upward
Process
How a program comes together
Discovery call & needs assessment
A conversation about your own — or your team's — current communication challenges and goals, followed by a structured assessment that identifies the specific gaps in business communication and negotiation language.
Program design
A curriculum built around real scenarios — your industry, your deals, your calls — not generic textbook English.
Live coaching
Weekly video sessions, fully remote, scheduled in CET-friendly hours.
Outcomes review
Progress is checked against concrete outcomes — leading a call solo, closing a deal, presenting to a client — not just attendance.
- MBA + Master in Sales Management & Marketing — ENEB, Barcelona (Distinction)
- MSc Team Management & Leadership — in progress
- TEFL Diploma, Cambridge/ITO
- ECBA — IIBA
About
From closing deals to coaching the language of closing them.
Before coaching, I spent over 20 years in B2B sales, key account management, and sales management — building client portfolios, negotiating high-value contracts, and leading sales teams. I hold a dual MBA and Master's in Sales Management and Marketing, completed with Distinction, and I'm currently completing an MSc in Team Management & Leadership.
This practice is built on one idea: the language of business and the language of sales are the same skill. Fluency isn't the goal on its own — confident, persuasive communication in front of a client is.
Who this is for
Coaching professionals at technology companies across Europe
Current and past work includes client-facing and sales-engineering professionals at global technology companies, predominantly based in Spain.
I have been learning English with Dieter for three years. I mainly have conversations with him about business and non-business topics. He corrects my mistakes in a very polite way, allowing me to continue speaking before reviewing the errors with me. AI may help you write emails, but it will never have the human touch that Dieter has. I look forward to my Monday class because I get to talk to someone I consider a friend.
— Francisco, Pre-Sales Engineer, Oracle EMEA
I've taken classes with Dieter for several years and seen my English improve consistently — the classes are dynamic and fun. I'm currently negotiating a significant deal in English and feel absolutely confident in my ability to conclude it successfully. Before working with Dieter, I sincerely doubt that would have been the case.
— Andres, Account Manager & Team Leader, Oracle EMEA
Dieter was Oracle's go-to person for communication and English, and he supported me in that role for two years. In that time, I saw significant improvement in both my English and my overall communication skills. His background as a Sales Executive and Sales Manager gives his coaching a business edge that a typical language coach simply doesn't have. I recommend him without hesitation.
— Valentin, Senior Sales Engineer, Talan Group Intl
English lessons with Dieter have become one of the most valuable parts of my week. He has a great ability to quickly identify areas to improve — vocabulary, fluency, pronunciation, or confidence — and gives constructive feedback without interrupting the natural flow of conversation. He creates a comfortable environment that makes it easy to speak freely, make mistakes, and learn from them. For me, Dieter is an excellent English teacher who has also become a friend.
