My name is Bartłomiej Stolarczyk, and I am a trainer, communication expert, and author.

One of my most acclaimed books, “Teach Them How to Treat You”, is also available in English. My core areas of expertise are assertiveness, phone-based customer relations (sales and customer support), ethical persuasion (in sales and negotiations), as well as management and leadership.

For over two decades, I have been helping people build a solid foundation for healthy communication. More than 20,000 participants have attended my training courses, and my book on assertiveness has sold over 24,000 copies, making it one of Poland’s major bestsellers on the topic.

I work with anyone who wants to take control of their life and business: from open workshop participants and international sales or IT teams to C-level executives in business and public administration. My philosophy is simple: assertiveness is an attitude of respect. I teach how to protect your boundaries without losing empathy for others.

My Offer:

• Assertiveness and Personal Development — my flagship authorial program on setting boundaries.

• Telesales and Customer Support — building long-term relationships and closing sales effectively.

• Ethical Persuasion and Negotiations — effectiveness based on partnership, not manipulation.

• International IT Customer Support and Helpdesk — crisis communication under time pressure.

• Management and Leadership — building mature teams and leadership strategies I have implemented in organizations such as Ferrero and the Chancellery of the Prime Minister of Poland.

I am a practitioner who teaches only what I have personally verified in training sessions across the globe (including India and Brazil). I thrive in international environments and am passionate about foreign languages, which is why I take great pleasure in delivering training for teams worldwide — both in-person and online.

Be effective, feel empowered, build your future.
