  • “I spent 2 days in an executive education course in which, by far, the most impactful 6 hours was led by Dr. Astray. She leveraged concise real world data and experience regarding leadership behaviors to drive introspection, group engagement, and thoughtful consideration of positive impacts driven by leadership behavior improvements.”

    Bruce Hopkins, SVP, Technology Executive, TD

    “Tatiana facilitated LEADING SELF & PEOPLE – Advanced Leadership – Session 1. What I found valuable was the way she helped participants apply leadership concepts in real-world scenarios. Her approach made the session both insightful and actionable, and I highly recommend her facilitation for leadership development programs.”

    Charetina Lougheed, VP President (A), Legal Services, Metrolinx

  • “I had the pleasure of taking a Leadership Essentials course with Tatiana in the Fall of 2024, and I highly recommend her as an instructor. She brings an engaging and dynamic approach to leadership training, making every session interactive and thought-provoking.

    What sets Tatiana apart is her ability to go beyond the surface of leadership concepts. Rather than simply presenting theories, she ensures a deep understanding by fostering meaningful discussions and encouraging different perspectives within our break out groups.

    Tatiana focuses on practical application, helping me apply material to ultimately become a better people leader opposed to a boss to whom others report to.”
    Evelina Luczko, P.Eng., PMP, Senior Manager, Metrolinx

  • “Working with Dr. Tatiana Astray was transformative for my career negotiations.

    When I found myself evaluating multiple job offers, I needed more than just negotiation tactics – I needed strategic guidance to make the right choice.

    Tatiana provided the right balance of expertise and insight.

    What sets Dr. Astray apart is her combination of thorough preparation and genuine investment in her clients' success.

    She came to our sessions prepared with industry benchmarks and actionable strategies, while taking the time to understand my career aspirations. Rather than focusing solely on negotiation techniques,

    Tatiana helped ensure I was making decisions aligned with my professional goals. The results speak for themselves – working with Dr. Astray proved invaluable, with the negotiated compensation package far exceeding the initial offer (delivering more than 10x return on the coaching investment).

    Beyond the numbers, she gave me the tools and confidence to effectively advocate for my worth. For anyone considering working with Tatiana, I can say with confidence that it will be worth the investment.

    Her expertise, preparation, and genuine commitment to her clients' success make her an exceptional negotiation coach. I give her my highest recommendation.”

    Jon Shantz, Manager, Strategic Projects at Open Farm Pet

  • “If you want to provide your team with an exceptional learning experience, you are in good hands with Tatiana.

    We have had the chance to invite her to facilitate a Negotiation course during large corporate events, and she captivated her audience by delivering impactful content and proposing realistic simulations that were transferable to our regular work activities.

    Tatiana understands her clients’ learning needs rapidly and will propose a learning solution that will make your project / event successful. She is one of the most talented facilitators with whom I had the opportunity to work over a career of 25 years.”
