"Assemble has been a deeply strategic partner to all of us at VaynerX for almost a decade. Right from the top, they’ve made a huge impact on our executive and senior leadership team, helping us tackle complex challenges and boosting our leadership game. They’ve been instrumental in training our mid-level managers on conflict resolution, navigating uncertainty, and sharpening communication skills. In short, they teach us the power of connection and the real value of clear, effective communication. Assemble is a true partner and part of our connective tissue, and they make our leadership culture stronger and more vibrant."

"Assemble has been game changing for Made By Gather. Learning and growing together as an executive leadership team has allowed us to not only grow as individuals and as a team but has helped our business grow along the way as a result. Through massive change over the last few years, Jill, Jami, Zamena — and their incredible team — have supported us, been thought partners, extensions to our People team, and friends of the brand that we can lean on. We are proud to work alongside the best in the business"
Shawn Austin, President, made by gather
“We initially engaged Assemble HR for HRBP support during one of our HRBPs maternity leave, and the experience far exceeded our expectations. From the start, the Assemble team took the time to deeply understand our needs and identified a senior, strategic HRBP who embodied our cultural values—a pension for action, a people-first mindset, and a strong focus on execution and results. We needed someone who could bring organizational alignment across two cultures following an acquisition, and Assemble matched us with Lillian, who was exceptional in every way. She brought extensive M&A experience, the perfect blend of IQ and EQ, and quickly became both a trusted partner and an expert on our organization while delivering meaningful impact from day one. Lillian embedded herself so seamlessly within our team that many did not realize she was external, raising the bar for what great HRBP partnership looks like and evolving into an ongoing strategic relationship. As we navigated the complexities of the “messy middle” post-M&A, Lillian was a critical partner in driving organizational design and alignment, made possible through Assemble’s ongoing collaboration, flexibility, and commitment to our success."

I highly recommend Assemble to organizations seeking to invest in their leaders while driving sustainable growth.”

Jill came to Unilever to deliver her masterclass on the power of feedback using her techniques of Candor, Courage and Care. It was one of the most well attended presentations we have delivered to date- with over 200 people live and many more dialed in from offices around the country. Our community just loved it!

“When the COVID crisis first hit, my team was struggling to define the “new normal” of how to work together in a virtual environment with new and competing priorities. Jill Katz facilitated a session on managing through crisis that was exactly what the team needed to evolve, share, and learn that it is OK not to be OK. The tools we received from her session have enhanced our ability to communicate with and manage our teams, no matter where they are based. We are so fortunate to have had the opportunity to work with Jill and, as a team, are forever changed for the better thanks to her coaching and support. Every professional team can benefit from working with Jill, she is the best of the best at getting to the core of issues and attacking them with ‘candor, courage, and care."
JILLIAN CUEFF, VP/GMM, WALMART.COM
“My experience with Jill can be summed up in five words: Luminous, Clever, Action, Vision and Integrity. Jill walks her walk with such infectious passion and energy which clearly leads to relationships with clients that bring joy and wisdom to the partnerships. There is never a day that Jill doesn’t show up, bring her best, inspire and coach others to do the same. And she does it with humour, candor and grace!”
Claude Silver, Chief Heart Officer, Vaynermedia

She has used her immense knowledge and know-how to improve our entire workforce, and I can’t think of a finer human being than Jill - plus she loves dogs as much as I do, so she can do no wrong!”
Jennifer Bandier, Founder, Bandier
“Assemble HR was a wonderful partner for our Diversity, Equity and Inclusion training. Zamena Ladak helped our teams confront their biases, understand the power of allyship, and learn to speak up. It was beneficial having her talent and insights to leverage as we continue to foster a workplace culture of respect and belonging.”

“There is a lot of good training material out there but there is only one Jill Katz.
These learning sessions are so powerful because of the connection and trust Jill builds with the participants. So many participants have told me how they are using the knowledge they have gained in the development programs Jill has built and facilitated at my company. She has an uncanny ability to build credibility so quickly. She cares so much and challenges participants to go outside their comfort zone. The results are impactful and lasting...”
Colleen Gangl, SVP, People, Dotdash Meredith
“I can’t say enough good things about the team at Assemble! I was in urgent need of support on my People team at Slice and Jami was a tremendous partner in helping us find a strong consultant, Kirsten, who jumped in quickly to learn our processes and provide day-to-day HR support while we were recruiting for a full-time position. Jami was responsive and willing to work with me to figure out how best to help and Kirsten was a joy to work with. As a Chief People Officer, I love having a core group of trusted partners and Assemble is on that list.”
Jac Meyer, Chief People Officer, Boll & Branch
“With Jill, you are getting it all – senior level strategic guidance, executive coaching, a culture champion, and nuts and bolts HR expertise.

Kelley Hicks, CFO, Burrow
“I have had the pleasure of working with Jill Katz over many decades and in every way she is an incredible leader, coach and professional. When we were looking for a partner to drive our L&OD efforts for our organization, she and her team at Assemble were the natural choice. Jill has introduced our emerging leaders to leading with Candor, Courage, and CareTM. She has given guidance to our greater organization through her masterclasses and had connected individuals through her monthly #AssembleNetwork. In each, her ability to connect and resonate with those learning from her is unmistakable. Jill brings clarity, simplicity, humor and humility to her interactions. It’s no wonder immediate trust and connection is created.”
Anna Ellis, VP, Human Resources, Theory

“Jill is an exceptional HR business partner. She clearly understands how to build high performing teams that deliver results.”
Tim Baxter, CEO, Express
“Assemble has exceeded our expectations with the transformation results from our engagement with Jill Katz. Client progress reports, action items and overall leadership results were shared continuously throughout the process. Jill handles her engagements with transparency candor and dignity – our internal stakeholders were immediately bought in to her approach. Executive Coaching can sometimes feel stale and even remedial. My leaders are asking to extend their assignments with Assemble – an overall inspiring partnership.”
Crist Stilianos, HR Business Leader, Tiffany & Co.
“Having signed up for Jill Katz’s Assemble networking group, I really had no idea what to expect. I thought maybe I’d virtually meet some people I didn’t know and then we’d talk about best practices, trends, etc. Little did I know I’d be treated to 4 weeks of Jill’s dynamic and engaging personality, her authenticity, her passion, her support, her humor, her brain, her network, her perspective and her collaborative assignments. Add to that the amazing people that have joined her Assemble forums that have quickly become new friends and it was an experience that far surpassed my expectations. I’ve learned a lot about myself in these sessions. And, I enjoyed it so much that I signed up for a second one 4 months later and it is just as fantastic - it’s the best 90 minute gift someone can give themselves. Jill is a very special leader with a gift for bringing people together and bringing out the best in them. I highly recommend signing up for one of her #AssembleNetwork forums.”
Michele Olton, SVP, Chief Talent Officer, Re:Sources - A Publicis Company
“My experience with Assemble has been nothing short of exceptional. We partnered with Assemble for People Operations services when an employee on our People team went on leave. We were lucky enough to have the privilege of Kirsten from Assemble joining our team for 6 months and she knocked it out of the ballpark, learning our processes with ease. Her attention to detail, thoughtfulness, kindness, professionalism, and work ethic were truly unmatched; her subject matter expertise enabled us to move many projects forward. Working with Assemble on our needs was always seamless as they were responsive, receptive, and incredibly kind. Any company that requires these supportive services would be lucky to work with Assemble’s team.”
Kendall Hurwitz, Senior Manager, People, Axoni
“If you are looking for a team to bring fun and excitement to workshops and training, look no further. Assemble is doing it right. Jill Katz, Zamena Ladak and the Assemble team are so bright, funny, and enthusiastic. They bring a fun, fresh and engaging approach to having difficult conversations. They have really helped our team progress in their careers and overall communication.”
