Breaking Down Silos: How One Exec is Blending Legal and HR to Drive Stronger Leadership

What happens when legal acumen meets people strategy at the executive level? In a recent episode of the HRchat Podcast, I sat down with Joshua Horenstein, the Senior Vice President, Chief Legal and Human Resources Officer & Corporate Secretary at Innophos, to explore what happens when one leader wears both legal and HR hats—and why it’s making him a stronger executive.

A Unique Dual Role with Powerful Impact

Joshua leads both the legal and HR functions at Innophos, a global phosphate company with 1,500 employees worldwide. It’s not a typical combo, but it’s one that brings unique advantages.

“Running both departments has made me better at both functions,” Joshua told me. “It made me a better lawyer, a better executive, a better leader overall.”

This dual perspective allows Joshua to offer comprehensive, integrated solutions that traditional, siloed departments often miss. Whether it’s navigating complex regulatory matters or supporting people through organizational change, he approaches challenges with a wide lens and a steady hand.

Navigating Transformations: Structure Meets Humanity

Over his 15-year tenure at Innophos, Joshua has helped steer the company through major transformations—including a $1 billion public-to-private sale. His ability to bridge the legal and human aspects of major transactions has proven invaluable.

“CEOs and boards like just having one person to talk to,” he said, noting how his multifaceted role streamlines communication and decision-making at the top.

Having one trusted leader accountable for both compliance and culture has helped Innophos manage change more smoothly and keep people at the center of business strategy.

ESG Leadership with Practical Purpose

Joshua also champions the company’s ESG (Environmental, Social, and Governance) efforts, pushing for initiatives that balance responsibility with results.

“I refuse to believe you can’t be a good environmental steward and also make money,” he said. For him, ESG isn’t about chasing trends—it’s about doing what’s right for the long term, with intention and realism.

This practical approach helps align ESG goals with business performance, fostering buy-in across leadership and frontline teams alike.

Mentorship and Culture: Bridging Borders

Mentorship is another central pillar of Joshua’s leadership style. Inspired by his own mentors, he’s launched several innovative programs at Innophos—including an English-Spanish “buddy system” that connects employees across regions.

The goal? To improve language skills, strengthen collaboration, and build cultural bridges within the workforce.

“These small actions have a big impact on engagement and inclusion,” he said. “It’s about creating connection across boundaries.”

Final Thoughts: Plan, But Stay Agile

When asked about advice for leaders navigating transformation, Joshua offered this grounded reminder:

“Plan…but part of that humility is recognizing it’s never going to go 100 percent to plan.”

It’s this balance—careful planning paired with adaptive flexibility—that defines Joshua’s approach to modern leadership.
