Independent Financial & Analytical Consulting

Maximum Distance.
Maximum Perspective.

Forensic FP&A, financial controls, and analytical systems built for organizations that need clarity, not simply confirmation.

What We Do

Analytical depth
at every engagement.

FP&A & Reporting
Multi-entity consolidations, driver-based budgeting, rolling reforecasts, and executive dashboards built to communicate clearly and hold up under scrutiny.
Forensic Controls
GAAP compliance reviews, intercompany reconciliation forensics, vendor audit, Benford's Law fraud detection, and systematic gap analysis that finds what others miss.
Automation & Analytics
Python, VBA, and Power BI systems that eliminate manual workflows, surface insight from complex data, and scale with the business rather than against it.
The Parallax Approach

Three angles.
One precise picture.

Parallax is the displacement of an observed object depending on the position of the observer. Measured from multiple vantage points, the true position becomes exact. Three distinct lenses. One unified methodology.

Results confirmed
by the people who saw them.

The analysis went well beyond what we had asked for. The freight overbilling finding alone justified the entire engagement, and then some. We now have controls in place we didn't know we were missing.

Founder & Principal

The work is forensic by nature. Most FP&A practitioners validate what already exists. The work at Parallax Apogee starts from first principles: questioning the data, tracing the methodology, and finding the number behind the number before any conclusion is reached.

Before finance, a career as a U.S. Army Infantry NCO and combat veteran. The discipline, the pressure-testing of assumptions, and the intolerance for ambiguity in high-stakes environments translated directly. Systematic decision-making under pressure is not a soft skill. It is infrastructure.

Founder Story

The Practice Built on
Pattern Recognition

Parallax Apogee mixes independent financial and analytical consulting with the discipline of military service, and a touch of astronomy, to serve Long Island's small to mid-market landscape.

“My service in the United States Army afforded me the opportunity to experience the dynamic, kinetic landscape of 2011 Afghanistan from inside the shoes of an Infantry Squad Leader. As point-man for my unit, I learned how to lead from the front; assess the situation, spot the anomalies, and communicate clearly to those behind me.”

The pattern recognition did not start behind a desk. It was forged in the mind of a 10th Mountain Division soldier who viewed the terrain from both the peaks of the Hindu Kush Mountains and the riverbed of the Arghandab. Navigating those landscapes required a precise understanding of the terrain and the tactics used by the enemy as they engaged with improvised explosive devices.

After his active duty service contract concluded, Leonard immediately marched out of Uncle Sam's office and into the world of accounting and finance. The regulations of the accounting world were a direct reflection of the doctrine within the Army, and it felt like coming home. Trading in Army Regulations and Field Manuals for Generally Accepted Accounting Principles, Lenny picked up the pace without missing a step, and as he broke trail through financial statements and reconciliations, he learned that the pattern recognition that got him through Afghanistan could also be leveraged during audits and monthly close.

“Pattern recognition in Finance and Accounting is just like walking point on deployment. You need to maintain constant awareness of what is going on around you and assess each new piece of information in a timely manner for maximum benefit to the unit or the business. It really boils down to probability weighting based on known and unknown variables. Think Bayes Theorem and counting cards, somewhere on that spectrum is an efficient method to engage pattern recognition.”

So what does this have to do with astronomy?

Alpha team laying down suppressive fire so bravo team can flank the enemy position. Horizontal and vertical analysis of the balance sheet and income statement. A combat veteran and a finance professional. The commonality is triangulation, using two known points to determine the distance to a third. In astronomy, the first rung of the cosmic distance ladder, this is known as parallax. Apogee is the point in an orbit where a body reaches maximum distance from the object it revolves around.

Parallax Apogee is named for that principle deliberately. Maximum distance between observation points produces maximum precision in the assessment, giving you maximum perspective on the operational environment.

Built on judgment developed under real pressure and applied to the discipline of financial review, Parallax Apogee works with growing companies operating in Long Island's small to mid-market landscape across three areas built on that same discipline. Management reporting, for owners who need to see their business clearly enough to decide which path to take at the fork in the road. Forensic controls and audit preparation, for companies that have grown fast enough that nobody has the time to go back and check whether their controls grew with them. And automation and analytics, for businesses still running critical processes through a spreadsheet that one person understands and everyone else is afraid to touch.

Strengthening the financial infrastructure of these businesses produces outcomes that compound across the region. Better decisions mean more disciplined hiring, more informed capital deployment, and the capacity to compete for contracts and growth opportunities that those companies currently lack the analytical foundation to pursue. Capital stays local. Jobs are retained and created. Businesses that are regional anchors today become stronger ones tomorrow.
