About Meridian

A fixed point of reference for complex decisions.

A meridian is the line navigators use to find their bearing. Meridian Axis Advisory LLC exists to give leadership teams that same clarity — an honest view of where the organization stands and a practical course to where it needs to go.

Our story

Built by operators, for operators.

Meridian Axis was founded on a simple observation: the hardest problems organizations face don't sit neatly inside “IT,” “finance” or “operations.” A network redesign changes how every site works. A new operating model depends on systems that can support it. Yet most advisors are expert in one side and guess at the other.

Our founders have spent their careers on both sides. Talmas has spent more than 17 years in enterprise technology — networking, security, cloud, automation and architecture across a global footprint of 30+ sites. Tsehaia brings roughly two decades of executive operations leadership, ultimately directing operational strategy across 41 schools and partnering with Finance on operating budgets exceeding $340M. Together they offer management, technology and operations consulting to organizations that need senior judgment without building a large internal leadership bench.

Technology, infrastructure & resilience

Talmas

Co-Founder & Principal — Technology

Talmas leads Meridian's technology practice, bringing more than 17 years of technology leadership across networking, security, cloud, virtualization, automation, monitoring and enterprise architecture.

That experience spans healthcare, where Talmas served as a network administrator, and enterprise environments with infrastructure across multiple locations — including a global footprint spanning 30+ sites — where mission-critical availability was measured in five nines.

Operations, governance & organizational performance

Tsehaia

Co-Founder & Principal — Operations

Tsehaia leads Meridian's operations practice, drawing on more than 20 years of executive operations leadership — much of it in education, where she ultimately directed operational strategy across 41 schools in New York, Connecticut and Rhode Island.

She has partnered with Finance on budgets, forecasts and fiscal policy for operating budgets exceeding $340M, built weekly operating and reporting cadences, and redesigned vendor-dependent services such as transportation for accountability, compliance and cost oversight.

Principles

How we hold ourselves accountable.

  • Independence

    We don't resell hardware, software or managed services, and we don't accept vendor commissions. Our only incentive is your outcome.

  • Senior attention

    The founders lead engagements personally. You won't be sold by partners and delivered by juniors.

  • Candor

    We tell leadership what is true, including when it's inconvenient. Good decisions start with an honest baseline.

  • Durability

    We design for the team that will run things after we leave — documentation, standards and ownership, not dependency.
