Connection to trusted specialists across executive search, recruiting, compensation, and HR operations. When a need falls outside our core work, you skip the noise and get to the right partner faster.

Clients usually call for one of two reasons: something thorny needs solving, or something important needs building. A leadership gap. A team losing traction. Culture drift. Foundations that need strengthening before growth exposes the cracks.
Most HR support is either highly tactical or overly theoretical. We’re neither. We bring sharp judgment, practical solutions, and experience that helps leaders move faster and build stronger organizations.
We understand the realities generic advisors often miss: regulated environments, clinical operations, thin margins, complex orgs, and the challenge of scaling without losing the mission.
You work directly with Elliot. He applies senior judgment where it matters most and brings in trusted specialists when the work is better done by others.
We approach people work like an operator, not a bureaucrat. Every recommendation starts with the end goal, then builds the team and structure to achieve it.
“By the time Elliot partnered with Mantra, we had gone through several iterations of our people function and needed a stronger approach to how we hired, developed, and managed the performance of our team.
Elliot helped us rebuild key elements of our people infrastructure — including leveling, performance management, and capabilities-based hiring discipline — while also serving as a trusted advisor to me on a handful of complex organizational decisions. He then helped us design and hire the right full-time people leader and set them up for success. Elliot’s high IQ/EQ, a joy to work with, and understands the realities of scaling a tech-enabled healthcare company and brings a rare combination of strategic clarity and practical execution.”
“Working with Elliot has been incredibly high-impact. He brings deep experience, quickly understands challenges, and moves to practical solutions with impressive speed.
His output is exceptional for the hours he dedicates – he builds trust with leadership fast and delivers meaningful progress almost immediately. He also helped us scale support by bringing in a strong fractional HR resource who added value right away.
If you need someone who can step in, earn credibility, and drive results quickly, I’d highly recommend Luminary.”
“Elliot was an invaluable partner during the HR transition at Character Biosciences and throughout my onboarding into the Head of People role. He thoughtfully outlined a comprehensive onboarding plan, ensured a thorough handoff of projects already underway, and partnered closely with me to implement the company’s first leveling matrix.
His organization, foresight, and collaborative approach helped me quickly get up to speed and cover more ground as a lean HR team of one. Elliot is exactly the kind of partner you want in your corner when navigating moments of change and growth.”
“Being coached by Elliot has been one of the most challenging and rewarding experiences of my career. In just six months, I’ve seen some of the most significant professional growth I’ve had in the past ten years.
Through weekly calls, he has helped me get on track for a promotion, coached me through learning a new market, and guided me in staying one step ahead of hiring managers. He encourages me to lead with data and present solutions with multiple paths.
Elliot’s coaching is practical, strategic, and transformational. He pushes you to grow while giving you the tools to succeed.”
“Elliot was instrumental in helping me transition from managing daily fires to driving high-level strategy.
He provided frameworks that allowed me to sharpen my lens on complex organizational issues and board management. By conducting deep-dive audits of my time and refining my communication style, we co-created an operating system that drastically reduced context switching.
This shift not only clarified my priorities; it significantly strengthened my ability to protect my focus for high-leverage work and provide a more distinct, valuable perspective to the CEO.”
“Working with Elliot has been a meaningful anchor during a period of significant scale and change in both my professional career and in my organization. I’ve valued having a thought partner who can move seamlessly between strategy and execution, helping me clarify priorities and make better decisions. He brings a rare balance of perspective and pragmatism, offering concrete, actionable ideas when needed while also knowing when to push my thinking to the right altitude.
I would wholeheartedly recommend Elliot to any executive leader navigating complexity and challenges who needs both a steady partner and a catalyst for growth.”
“Elliot brings a depth of People experience to any company in its early stages — offering a steady hand, broad HR knowledge, and an ability to navigate and make sense of complicated situations. He applies this expertise to build up HR functions, create foundational policies and procedures to guide companies, and serve as a trusted advisor to senior leadership.”
