In my current position, I facilitate the Deloitte Global Managing Director promotion process. I connected Ilona with a candidate who was looking for a coach that could help him address developmental feedback and really up his game. As a result of the coaching and this candidate’s hard work at his own development, the promotion panel unanimously supported his advancement, recognizing him as one of the strongest candidates to be evaluated in recent memory. Ilona went out of her way to ensure he was a success – connecting with me to understand the program and being there when the candidate needed her, even if that meant a debrief the night before his interview at 10PM.

We will certainly look to Ilona again when we have a candidate who needs coaching support to help bring out their best.

Christina Lexa Organization Development Manager, Deloitte Global

I enjoyed your class instruction this week and I feel very much encouraged and empowered. I am passionate about leadership, professional, and organizational development and this week has sparked a bit of “light” in me.  I’m excited to self-improve, employ some of the techniques I’ve learned, and to learn more along the way. Hope to cross paths again!


Ilona is smart, skilled and delivers on her ideas with professional style. We connected with Ilona for ideas and strategic direction for our new industry mentoring program, and she is a wealth of knowledge and solid recommendations. She created two customized webinar programs for us to connect our mentees and mentors with each other for a virtual dialogue. She shared practical tools to build their mentor relationship, which we now have as an ongoing resource. We are grateful for Ilona’s time, energy and expertise and would work with her again anytime!

Ilona and colleague were critical partners in helping us shape and deliver NRECA’s leadership development program that was customized to help drive organizational culture change. Ilona was a great sounding board and advisor with interesting ideas on how best to create a program that would have immediate impact and long-term sustainability. She and her partner have run five different cohorts for people leaders and individual contributors over the past 18 months. The HR team has received numerous accolades from program participants and their managers on the strength of the program. I highly recommend Ilona to any organization seeking leadership development and coaching consulting.

I invited Ilona to present techniques on handling Difficult Conversations to a roundtable group of seasoned senior executives. They were impressed by her knowledgeable command of the topic and her credibility. She provided them with very practical and useful techniques that could be applied immediately to their own employee issues. Within the first week of her presentation, I’ve heard positive results from applying the techniques. I was impressed by her ability to create a “dialogue” with the group on the topic versus simply “educating” them, which is essential for senior audiences.

Carin Gendell Forum Leader at Renaissance Executive Forums

Thank you very much for a terrific presentation and facilitation of our World Café. At my weekly management team staff meeting today, your portion of our two-day program stood out as one of the highlights.  Feedback has been positive, with folks really enjoying the opportunity to work together in developing solutions.

Senior Executive Government Agency

My manager rated my performance for FY14 as “Materially Exceeds Expectations,” which is the highest rating. I wanted to thank you for all your guidance and help this year. I owe this rating in part to your mentorship and coaching.

Senior Leader Commercial Transportation

In my 20 years as a management consultant, I have had a wide range of training; some valuable, some not. The professional coaching that I have received from Ilona Birenbaum over the last eight months, however, has been the most helpful external support I have ever received. Ilona allowed me to set the agenda, ensuring that the issues we address are the ones most important to me and directly related to my ability to succeed. Ilona is very direct — she tells me things I need to hear; challenges me to consider ideas that might be uncomfortable. Yet she is understanding and compassionate; Ilona quickly earned my trust and respect, and has come to feel like a friend and confidante. Not only does Ilona provide pragmatic solutions, but also emotional support. After we talk, I feel less stressed and more energized, better prepared to tackle the challenges in front of me.

If you are looking for someone who will dig in deep, listen well, be honest, watch your back, and offer actionable advice, I highly recommend Ilona as an executive coach.

Eric Marks Management Consulting Practice Leader

Working with The Wynhurst Group is like a breath of fresh air. Professional, experienced, and known for creative solutions, the leadership development expertise of this organization is top-notch. Ilona in particular is an outstanding executive coach and yields successful results for both her coachees and her client organizations.

Meg Drago Head of Global HR

Ilona always knows the right questions to ask, shifting the discussion between coaching and consulting to help me serve ASN and its leaders, staff, and 15,000 members much more effectively. As a result of Ilona’s insights, guidance, and mentorship since 2008, I’ve grown personally and professionally, while the society has exceeded every metric and expanded into new, exciting ventures.
