There is, however, a real disambiguation risk with this name. 'Tomislav Mihaljević' is not uncommon in Croatia and the broader former-Yugoslav region, so before relying on any number you find online, confirm these three identifiers: (1) the person is a medical doctor (M.D.) and executive, not a politician, athlete, or entertainer; (2) his current employer is The Cleveland Clinic Foundation (EIN 34-0714585); and (3) his name appears in Cleveland Clinic's publicly filed Form 990 documents as 'MIHALJEVIC, M.D., TOMISLAV' with the title 'DIRECTOR, PRESIDENT & CEO.' If all three match, you have the right person.
What 'net worth' actually means here
Net worth is simply total assets minus total liabilities. For a private individual like Dr. Mihaljević, who is not a publicly traded executive required to disclose equity holdings, there is no official, audited net worth figure. What exists instead are estimates, built by aggregating every observable income signal and then making assumptions about savings rates, investment returns, taxes, and spending. For most healthcare executives in the United States, the primary observable signal is executive compensation disclosed in the employer's annual IRS Form 990, a public document that nonprofits must file. Everything beyond that, including personal investments, real estate, and board-related income, requires inference or self-reporting, neither of which is guaranteed to be complete or current.
This is an important baseline to set before looking at any specific number. A figure like '$20 million' or '$1.4 million' is not a bank balance. It is a model output, and the model's quality depends entirely on what data was fed into it and what assumptions were made. That is why the same person can show up with wildly different estimates on different sites, and why you should treat every figure as a range, not a fact.
Three different types of sources report numbers for Dr. Mihaljević, and they are not remotely consistent. Here is what each one says and how it arrives at its figure:
| Source | Stated Net Worth | Methodology | Reliability |
|---|
| IRS Form 990 (Cleveland Clinic Foundation, 2022) | $6,256,750 total compensation (single year) | Legally required public disclosure; includes base pay, bonus, incentive, and deferred compensation | Highest — primary source |
| Axios Cleveland (journalism) | $6.6 million CEO pay cited | Derived from 990 filings; reported in editorial context | High — cites primary source |
| ceonetworths.com (Mar 2025) | ~$20 million net worth | Cumulative compensation estimate plus board income and assumed investments; no asset/liability breakdown | Low-moderate — estimate only, no citations |
| MarketScreener (Feb 2026) | $768,205 | Appears to reflect disclosed securities/insider holdings only; not a full net worth calculation | Limited scope — insider asset view, not total wealth |
| PeopleAI (Feb 2026) | $1.41 million | Self-described 'social factors' model; methodology not clearly defined | Low — methodology opaque, disclaimer present |
The only number that comes from a legally mandated disclosure is the annual compensation figure on the Form 990. Everything else is an estimate layered on top of that. The ceonetworths.com figure of approximately $20 million is the most commonly cited 'net worth' estimate in search results and is at least conceptually grounded: if Dr. Mihaljević has earned executive-level compensation for roughly a decade across Cleveland Clinic Abu Dhabi and Cleveland Clinic's main campus, cumulative pre-tax earnings in the range of $30 to $50 million are plausible, and a net worth of $20 million after taxes, spending, and savings assumptions is within a reasonable range. But it is still an estimate, not a verified figure.
Where the money comes from: income and asset categories
Executive compensation at Cleveland Clinic
This is by far the most documented income source. The 2022 Form 990 for The Cleveland Clinic Foundation lists Dr. Mihaljević's total compensation at $6,256,750 for that fiscal year, broken into base compensation, bonus and incentive compensation, other reportable compensation, and nontaxable benefits. Axios Cleveland reported a figure of $6.6 million in a related year's context. ProPublica's Nonprofit Explorer aggregates these figures across multiple filing years and links directly to the underlying 990 PDFs, allowing anyone to track how his compensation has changed since he became CEO in 2018.
Board and directorship income
MarketScreener's insider profile for Dr. Mihaljević notes board and director affiliations, including connections to GE Healthcare-related entities. Board seats at for-profit companies typically come with cash retainers, equity grants, and meeting fees that can add meaningfully to annual income. However, because these are not disclosed in the 990 (which covers only Cleveland Clinic compensation), the exact amounts are not publicly confirmed. Net worth estimators that include board income are making an inference, not citing a disclosure.
Prior career earnings
Dr. Mihaljević was CEO of Cleveland Clinic Abu Dhabi before his current role and a practicing cardiac surgeon before that. Cardiac surgeons in senior academic hospital roles typically earn $600,000 to over $1 million annually in the United States, and executive roles in the Gulf region often carry additional compensation packages. These years of earnings form the financial base that any cumulative net worth estimate needs to account for, even if exact figures are not publicly available.
Investments, real estate, and deferred compensation
The Form 990 does disclose retirement and deferred compensation components within its Schedule J structure, but it does not reveal personal investment portfolios, real estate holdings, or brokerage accounts. Net worth estimators that include these categories are using assumptions, typically a standard savings-rate model applied to the known compensation figures. Whether Dr. Mihaljević's actual savings and investment behavior matches those assumptions is unknown.
Why estimates vary so much across sources
The gap between $768,000 (MarketScreener) and $20 million (ceonetworths.com) is enormous, and it is not a mistake so much as a reflection of what each source is actually measuring. MarketScreener focuses on insider shareholdings and disclosed securities, which for a nonprofit executive are minimal or nonexistent since Cleveland Clinic does not issue publicly traded stock. Its figure almost certainly captures only a narrow slice of disclosed financial interests, not total personal wealth. PeopleAI's $1.41 million figure is based on what the site itself describes as 'social factors,' a vague methodology that likely does not incorporate the 990 compensation data at all.
Timing also matters. A figure last updated in March 2025 reflects data available at that point. If a new Form 990 has been filed since then, or if Dr. Mihaljević's compensation changed, the estimate is already stale. On top of that, net worth is not static: market movements, real estate valuations, and changes in deferred compensation balances all shift the number continuously. Any figure you see online is a snapshot, not a live balance sheet.
For readers in the Balkans and Eastern Europe, there is an additional layer to keep in mind. Compensation figures reported in U.S. dollars reflect a very different economic context than Croatian or regional salaries. A $6 million annual compensation package is exceptional even by American standards, where it places Dr. Mihaljević among the highest-paid nonprofit executives in the country. Converted to Croatian kuna or euros, the figures look even more extreme, which can make it tempting to assume the net worth estimates are similarly scaled. They may be, but the underlying methodology does not change just because the currency conversion is striking.
How to verify this yourself: primary sources and a quality checklist
The best starting point is ProPublica's Nonprofit Explorer, which you can find by searching the site for 'Cleveland Clinic Foundation' or by EIN 34-0714585. From there, you can download the actual Form 990 PDFs for multiple years and look up the compensation tables for Dr. Mihaljević directly. This is free, publicly available, and updated as new filings are submitted. It gives you the most reliable income data available for any private individual in the United States.
For secondary verification, Cleveland Clinic's own newsroom confirms his role and tenure, and the Croatian outlet Večernji.hr published a profile interview in November 2023 that corroborates both his identity and his leadership position for readers approaching this from a Croatian-language perspective.
When evaluating any net worth source, run it through this checklist before trusting the figure:
- Does the source cite the IRS Form 990 or another primary financial document? If not, treat the figure with skepticism.
- Does the source explain its methodology, including how it moves from annual compensation to cumulative net worth? A site that just shows a number with no explanation should be treated as a rough guess at best.
- Is the figure dated? Check when it was last updated. Figures more than 12 months old may not reflect the most recent 990 filing.
- Does the source confuse gross income with net worth? These are very different things. Annual compensation of $6 million does not mean net worth is $6 million.
- Does the site include a disclaimer that the figure is an estimate? Responsible sources do. Sites that present estimates as facts are a red flag.
- Is the person correctly identified? Confirm M.D. title, Cleveland Clinic, and the 990 name match before relying on any number.
Putting it all together: what number to use and how to update it
The most defensible estimate for Dr. If you are comparing other Balkan figures, you may also want to review Dragoslav Ilic net worth as a related example of how these estimates differ by source. When comparing other similar online claims, you can also review tomislav uzelac net worth to see how estimate methodology and source choice can swing the final number. If you are researching another public figure's finances, you may also want to compare this approach with <a data-article-id="16D274E9-B9DF-4082-B0A3-342F6AAF1F2A">Dragoslav Ilic net worth</a>. Tomislav Mihaljević's net worth as of April 2026 is in the range of $15 million to $25 million, with $20 million being the commonly cited midpoint. If you want, you can also compare this with vasilije micic net worth estimates to see how different methodologies can change the range Tomislav Mihaljević's net worth. This range is built on confirmed annual compensation of approximately $6 to $6.6 million per year as disclosed in Form 990 filings, applied across roughly eight years in top executive roles at Cleveland Clinic (plus earlier career earnings as a cardiac surgeon and executive in Abu Dhabi), minus reasonable assumptions for U.S. federal and state income taxes, living expenses, and savings allocation. It also allows for income from board affiliations that are referenced but not fully disclosed. This is a reasonable, evidence-anchored range, not a confirmed figure.
The figures from MarketScreener ($768,205) and PeopleAI ($1.41 million) should not be used as net worth estimates. They are either measuring a narrow slice of disclosed assets or using an opaque social-signal model that does not incorporate the most relevant public data. The Axios-cited $6.6 million figure is the best single-year compensation reference, but it should not be read as net worth either.
To keep this estimate current going forward, check ProPublica's Nonprofit Explorer every 12 to 18 months for new 990 filings from The Cleveland Clinic Foundation. When a new filing appears, update the cumulative compensation base and adjust the net worth range accordingly. If Dr. Mihaljević's role changes, is disclosed in a new regulatory filing, or if he moves to a for-profit institution that requires SEC compensation disclosures, the data quality will shift significantly in one direction or another.
For context within the region this site covers: Dr. Mihaljević represents a relatively unusual category among Croatian and Balkan public figures in that his wealth is derived almost entirely from a professional executive career in the United States nonprofit healthcare sector, with legally mandated annual disclosures, rather than from business ownership, politics, or media, which are the more common wealth drivers for the Croatian and regional figures documented elsewhere on this site. That makes his compensation traceable in ways that many regional figures' finances are not, even if the full net worth picture remains an estimate. If you are specifically looking for Josip Broz Tito net worth, the same basic approach applies: focus on reliable, primary-source disclosures rather than one-off internet estimates.
