Based on publicly available records as of May 31, 2026, Eric Ferdinand Ciliberti, MD has an estimated net worth in the range of $3 million to $10 million. That range reflects his dual income streams as a practicing neurologist and as founder of a supplement company (Relaxium) that reached Inc. 5000 status, but it carries meaningful uncertainty because no salary disclosures, property records, or personal financial statements have been made public. If you are looking specifically for Stephen Nicholas MD net worth, keep in mind that the same lack of public financial disclosures can make any figure speculative. Think of that range as a reasonable starting bracket, not a confirmed figure.

Confirming the right Eric Ciliberti, MD
There is more than one person named Eric Ciliberti in Florida, so it is worth pinning down the exact individual before attaching any financial estimate. The person this article covers is Eric Ferdinand Ciliberti, MD, MS, a board-certified clinical neurologist practicing in Tamarac, Florida. His Florida Department of Health license number is ME86015, status is Clear/Active, his primary practice address is 6233 N. University Drive in Tamarac, and his license expiration date is January 31, 2027. He began practicing on July 1, 1991, giving him over three decades in medicine as of 2026. His Doximity profile cross-confirms the full name (Eric Ferdinand Ciliberti MD MS) and specialty (Neurology). Outside clinical practice, he is publicly identified on Relaxium's website as a clinical neurologist, founder of The American Behavioral Research Institute (ABRI), and the developer of Relaxium sleep supplement products. An Inc. 5000 PR Newswire announcement also calls him a board-certified physician, clinical neurologist, and sleep expert in connection with ABRI and Relaxium. If you are researching a different Eric Ciliberti, the middle name Ferdinand and license number ME86015 are your best disambiguation tools.
What net worth means and how physician net worth is estimated
Net worth has a simple definition: total assets minus total liabilities. Assets include cash, investment accounts, real estate equity, business ownership stakes, and anything else of monetary value. Liabilities include mortgage balances, student loans, lines of credit, and other debts. Whatever is left after you subtract one from the other is net worth. A positive number means you own more than you owe; a negative number means the opposite.
For most physicians, net worth is not a matter of public record the way it is for, say, a publicly traded company's executive who must file disclosures. Doctors in private practice or LLC ownership are not required to publish salary figures, balance sheets, or asset lists. That means any estimate has to be built from proxy signals: specialty income benchmarks, business ownership signals, publicly recorded assets like real estate, and regulatory or court filings that reference financial matters. Methodology transparency is everything here, which is why each section below explains exactly what data was used and where gaps remain. Other physician net worth profiles on this site, including those for figures like Dr. Gary Michelson and Kingsley Chin, MD, face the same estimation challenge and use a similar framework.
Verified income signals: practice, specialty, and business roles
Neurology is a physician specialty with above-average but not top-tier compensation. According to Medscape's most recently published physician compensation surveys, neurologists in the United States earn a median income in the range of $280,000 to $320,000 annually. Dr. Ciliberti has been licensed since 1991, placing him in a senior career stage where compensation often trends toward or above the top of that range, especially if he maintains an active clinical practice alongside outside ventures. No specific salary figure for Dr. Ciliberti has been disclosed in any public source reviewed for this article.
Beyond clinical practice, Dr. Ciliberti holds a visible entrepreneurial role. Relaxium, marketed as a drug-free sleep supplement, was associated with The American Behavioral Research Institute (ABRI), a Florida LLC in which Dr. Ciliberti is listed as a founder and manager. Relaxium achieved Inc. 5000 recognition, which indicates the business crossed a meaningful revenue threshold. However, being listed on the Inc. 5000 reflects company revenue growth, not owner compensation or profit distributions, so it cannot be translated directly into a personal income figure. The FDA issued a warning letter to ABRI in April 2025 related to a clinical investigation for Relaxium, listing Timea Ciliberti as Executive Chair and CEO at that time. This suggests the business is an active, operating entity with regulatory exposure, but the warning letter does not contain any financial disclosures.
Two court dockets in public records link Dr. Ciliberti's full legal name to active litigation. A GEICO-related case filed January 28, 2026 names Eric Ferdinand Ciliberti, MD as a defendant, as does a Labor/FLSA matter filed May 9, 2024 that also names ABRI as a defendant. These are identity confirmation signals, not financial disclosures. Active litigation is worth noting in any financial profile because unresolved legal liabilities can affect net worth in ways that cannot be estimated from the outside.
Documented assets and ownership interests
The most verifiable asset-related signal is Dr. Ciliberti's ownership role in American Behavioral Research Institute, LLC. Florida LLC annual report filings confirm Eric Ferdinand Ciliberti as listed in the entity, and a business entity aggregator (City-Data) notes him as Manager/General Partner for entity ID 27-0855860, with a Boca Raton address. Business ownership in an Inc. 5000 company can represent meaningful asset value, but LLC equity is privately held and not subject to public valuation disclosure. Without a balance sheet, purchase price, or a known transaction, the ownership stake's dollar value remains unquantifiable.
No real estate records, brokerage accounts, or personal property filings tied to Dr. Ciliberti appeared in the sources reviewed for this article. That absence does not mean assets do not exist; it means they were not discoverable through the public records reviewed here. Florida property records are publicly searchable by name through county property appraiser websites, and those searches would be the logical next step for anyone wanting to add real estate equity to this estimate.
Net worth range estimate and how it was calculated
Working from the proxy signals above, here is how the $3 million to $10 million range was constructed. For more perspective on how people present physician financial summaries, see Dr. Gary Michelson net worth as a related comparison point. A senior neurologist with 35-plus years of practice who has maintained consistent annual income in the $280,000 to $320,000 range accumulates substantial savings over time, assuming standard wealth-building behavior (retirement accounts, investment contributions, paying down a mortgage). Even with conservative assumptions, a physician at that career stage and income level who has been disciplined about saving would commonly reach $2 million to $5 million in net worth from clinical income alone. The ABRI/Relaxium business adds upside: a consumer supplement brand with Inc. 5000 recognition could carry a market value anywhere from a few hundred thousand dollars to several million depending on revenue, margins, and whether the brand has been valued or sold. That business component pushes the upper bound of the range meaningfully higher. Pending litigation is an offsetting liability factor that is unquantifiable but real. The range of $3 million to $10 million reflects that wide uncertainty band.
| Component | Estimated Contribution | Confidence |
|---|---|---|
| Clinical neurology career earnings (net savings/investments) | $2M – $5M | Moderate (based on specialty benchmarks and career length) |
| ABRI / Relaxium business ownership stake | $500K – $4M+ | Low (private LLC, no disclosed valuation) |
| Real estate equity | Unknown | Very Low (no records located) |
| Litigation liabilities | Unknown offset | Very Low (cases active, no judgments disclosed) |
| Total estimated net worth range | $3M – $10M | Low-to-Moderate |
Confidence level, why numbers vary, and data limitations
The overall confidence level for this estimate is low-to-moderate. That means the range is directionally reasonable but could be off by millions in either direction. Here is why that gap exists and why it matters for readers who want to use this number responsibly.
- No public salary disclosure: Physicians in private practice or LLC structures are not required to report compensation publicly. Every dollar figure here is derived from specialty benchmarks, not Dr. Ciliberti's actual pay.
- Private LLC ownership: ABRI's financial statements are not public. An Inc. 5000 listing confirms revenue growth but does not reveal profit margins, owner distributions, or what the company would sell for.
- No real estate records found: Property equity is often a large share of physician net worth, and without Florida county-level property appraiser data, this article cannot include it in the estimate.
- Active litigation: Two active court cases were identified. Unresolved legal matters can create contingent liabilities that reduce actual net worth in ways no outside observer can calculate.
- Time sensitivity: Net worth figures change. Business valuations, real estate values, investment portfolio performance, and litigation outcomes all shift the number. This estimate reflects what is knowable as of May 31, 2026.
- Name disambiguation risk: Any source that mentions 'Eric Ciliberti' without the middle name Ferdinand or the MD credential should be treated cautiously, as a different person could be involved.
For context, physician entrepreneur net worth profiles carry similar uncertainty regardless of the subject. Profiles like those for Steven Cyr, MD or Brendan Carr at Mount Sinai face the same structural limitation: when compensation is private and business holdings are not publicly valued, the estimate is only as good as the proxy data available.
How to check sources and update this estimate yourself
If you want to refine this number or verify it against primary sources, here is a practical checklist of what to look up and where. If you are comparing other physician estimates, you can also review the steven cyr md net worth range and the sources used to build it.
- Florida DOH MQA portal (flhealthsource.gov or the MQA search): Search by license number ME86015 or the name Eric Ferdinand Ciliberti to confirm active licensure, specialty, and any disciplinary actions that might affect practice status or income.
- Florida Division of Corporations (sunbiz.org): Search for American Behavioral Research Institute, LLC to pull the most current annual report, view registered agents and officers, and check for any dissolution or status changes.
- County Property Appraiser records: Search Broward County and Palm Beach County property appraiser websites by the name Ciliberti to find any real estate holdings and their assessed values. Appraised value is not the same as market value, but it gives a floor estimate.
- FDA Warning Letter database (accessdata.fda.gov): Search for American Behavioral Research Institute to review the April 2025 warning letter and any subsequent agency responses, which may signal the company's current compliance status.
- PACER (federal court records): Search for Eric Ferdinand Ciliberti to track the GEICO case and the FLSA matter. Look for settlements, judgments, or dismissals, any of which could affect the liability side of the net worth equation.
- Justia and CourtListener (free alternatives to PACER): Run a name search for Eric Ferdinand Ciliberti to monitor docket updates without a subscription.
- Inc. 5000 archive (inc.com): Search Relaxium or American Behavioral Research Institute to find the original Inc. 5000 listing, which will include the revenue growth rate and sometimes the revenue range, giving you a rough anchor for business valuation.
- Doximity or Healthgrades: Cross-check specialty, hospital affiliations, and practice address to confirm the subject has not changed practice settings, which could affect income trajectory.
When you gather those records, apply the same assets-minus-liabilities framework used here. Add up what you can verify (real estate equity from the property appraiser, estimated retirement savings from career length and income benchmarks, any business valuation signals you find), subtract known liabilities (mortgage balances from county records, any judgment amounts from court filings), and you will arrive at a more grounded range than any single source can provide. Updating the estimate annually, or after a major event like a court judgment or a business sale, is the most accurate way to track a private figure's net worth over time.
FAQ
How can I verify whether this Eric Ciliberti MD is the same person in the net worth estimate?
Use two identifiers together, middle name Ferdinand and Florida medical license number ME86015. Then confirm the practice location in Tamarac and any matching business role in ABRI (manager/founder) before you compare any financial signals to avoid mixing up people with the same first and last name.
Why can’t the Inc. 5000 or ABRI information be turned into a precise personal net worth number?
Inc. 5000 describes company revenue growth, it does not reveal owner pay, profit distributions, or equity value. Even if ABRI is active, LLC ownership stakes are typically private, and without a balance sheet or transaction price, you cannot reliably convert business success into personal assets.
Does the GEICO case or the FLSA case mean Dr. Ciliberti’s net worth is definitely lower?
Not necessarily. Pending or unresolved litigation can represent potential liability, but the impact depends on outcome, insurance coverage, court-awarded damages, and whether claims are settled or dismissed. Without judgment amounts and final results, the cases are best treated as an uncertainty factor, not a confirmed liability.
What public records are most likely to help estimate real estate equity in Florida?
Start with county property appraiser search by name, then check ownership history, assessed value, exemptions, and mortgage-related public documents if available through recorder or clerk databases. Equity estimates improve if you can find purchase dates and financing details, not just current assessed values.
If no salary is disclosed, how do analysts usually bound the income side for a long-practicing neurologist?
They rely on published specialty compensation medians and then adjust for career stage, years in practice, and whether the physician likely maintains active clinical work. A key caveat is that private practice overhead and employment structure (employee vs owner-operator) can change take-home income materially.
How should I interpret the range of $3 million to $10 million, is it meant to be exact or conservative?
It is a directional bracket, not a point estimate. The lower end is primarily savings accumulation from clinical income, while the upper end assumes additional value from private business ownership and possibly investment growth. Litigation risk is acknowledged but not priced, so the range can shift after outcomes or business valuation events.
What would most likely change the estimate quickly, compared with normal annual drift?
Big changes usually come from a court outcome (settlement or judgment), a business sale or liquidation, large asset purchases like a home, or major refinancing that alters mortgage balances. Routine market gains on retirement accounts can move net worth, but typically slower than discrete legal or transaction events.
Can I use this net worth range to make decisions, like contacting the physician or investing in anything?
Be cautious. Net worth estimates are inherently uncertain and may not reflect liquidity, current cash flow, or contingent liabilities. For anything transactional or financial, rely on direct disclosures, contracts, and audited or verifiable financial documents rather than a public estimate range.
What’s the fastest way to refine the estimate beyond what the article already checked?
Run targeted Florida property appraiser searches for equity, look for ABRI ownership and any later LLC filings that could indicate capital changes, and review the most recent court docket updates for case status or settlement terms. Those three areas typically provide the most incremental signal.
How can I avoid being misled by other websites that list a single net worth number?
Treat single-number claims as lower-quality unless they explain data inputs, math assumptions, and confidence level. If you cannot identify whether the figure came from verified property records, retirement account approximations, or any business valuation, it’s safer to use a range and update it only when primary records change.
