What We Use in Our Methodology

To find the top financial advisors in Oak Brook, we first identified all firms registered with the SEC in the city. Next, we filtered out firms that don't offer financial planning services, those that don't serve primarily individual clients and those that have disclosures on their record. The qualifying firms were then ranked according to the following criteria:

  • AUM
    Firms with more total assets under management are ranked higher.
  • Individual Client Count
    Firms who serve more individual clients (as opposed to institutional clients) are ranked higher.
  • Clients Per Advisor
    Firms with a lower ratio of clients per financial advisor are ranked higher.
  • Age of Firm
    Firms that have been in business longer are ranked higher.
  • Fee Structure
    Firms with a fee-only (as opposed to fee-based) compensation structure are ranked higher.

All information is accurate as of the writing of this article. This list may include firms that have a business relationship with SmartAsset, in which SmartAsset is compensated for lead referrals. Such relationships have no impact on our rankings, and firms are included and ranked based strictly on the above criteria.

Landmark Capital

Landmark Capital, Inc. works with a mix of non-high-net-worth individuals, high-net-worth individuals, pension and profit-sharing plans, corporations and family foundations.

Landmark provides both asset management and financial planning services to its clients. Financial planning will typically touch on topics like retirement planning, tax management, estate planning, risk management and education funding. Landmark has an investment minimum of $1 million, which it may negotiate at its discretion.

Landmark Capital is a fee-based firm. That means certain on-staff advisors can receive commissions from insurance or securities sales, which is a potential conflict of interest. Despite this, the firm abides by fiduciary duty.

Landmark Capital Background

Landmark Capital was established in Oak Brook in 2017 by Thomas C. Reynolds, who continues to serve as the firm’s president. Kathleen A. Gfrorer is the firm’s vice president, and Sherlyn E. Brubeck is the only other advisor on staff. 

Asset management fees will depend on which of the firm’s programs you participate in. They go as follows:

  • Landmark Asset Management Program: This fee will be a negotiable percentage of your AUM that won’t exceed 2%.
  • Financial Advisor Program: This uses a wrap fee program made available through Securities America Advisors. There is a maximum fee percentage of 3%.
  • Managed Opportunities Program: Again, this program comes with a wrap fee program made available through Securities America Advisors. The maximum fee percentage for this is 2.20%, though most fees are between 1% and 1.25%.

Financial planning fees will be charged at an hourly rate of up to $500. An estimated total will be presented to the client before any work is done. Then, the client will pay half of the total before and the remainder of the fee once the completed plan has been presented.

Landmark Capital Investment Philosophy

Landmark Capital uses a handful of investment strategies when constructing clients’ portfolios. Its primary choice is the “core and satellite” approach. This involves investing in a foundation of domestic stocks and fixed-income securities (or funds representing them). Then, your advisor will surround these core investments with securities from emerging markets, high-yield bonds or alternative investments, like real estate securities.

The firm seeks to personalize its services on a client-to-client basis, tailoring its investment strategy to each client's portfolio size, risk tolerance, investment objectives and time horizon. The firm takes these factors into account and uses them to formulate an asset allocation and investment strategy that’s best equipped to produce success over the long term.

Stonebridge Wealth Management

Stonebridge Wealth Management, LLC has been an investment advisor in Illinois since 2013. It serves both non-high-net-worth individuals and high-net-worth individuals.

Stonebridge provides fee-based investment management, financial planning and consulting services to its clients. The firm generally imposes a minimum account size of $500,000, although it may waive this at its discretion.

Some of the advisors at this firm can trade securities on a commission basis. Although this represents a potential conflict of interest, the firm's fiduciary duty requires it to act in clients' best interests at all times.

Stonebridge Wealth Management Background

Stonebridge Wealth Management was formed in 2013. It has two principal owners: William Laipple and Christopher Plahm.

The firm calculates investment management fees as a percentage of each client's AUM. The exact percentage is negotiable, but won’t exceed 1.5%. Financial planning fees may be fixed rates between $1,500 and $10,000, or an hourly fee of $500.

Stonebridge Wealth Management Investment Philosophy

Stonebridge Wealth Management’s investment approach is grounded in the belief that markets are efficient in the long term. The firm typically invests in open-end mutual funds and exchange-traded funds (ETFs) for most of its clients. In special circumstances, though, it may also invest in equities, warrants, fixed-income securities, municipal securities, private placements, pooled investment vehicles, structured products, corporate debt obligations, variable annuities and real estate investment trusts (REITs).

The firm recognizes that no two clients have identical financial situations, so it makes sure to tailor its services and investment strategy to each client’s investing goals, time horizon, relationship with risk and cash flow needs, among other factors.

How Long $1 Million Lasts in Retirement

SmartAsset's interactive map highlights places where $1 million will last the longest in retirement. Zoom between states and the national map to see the top spots in each region. Also, scroll over any city to learn about the cost of living in retirement for that location.

Rank City Housing Expenses Food Expenses Healthcare Expenses Utilities Expenses Transportation Expenses

Methodology We weighed potential expenditures for a prospective retiree with a  $1 million nest egg to assess how many years that fund would cover in retirement in America’s largest cities.

We applied cost of living data from the Council for Community and Economic Research to adjust those national average spending levels based on the costs of each expense category (housing, food, healthcare, utilities, transportation and other) in each city. Using this data, SmartAsset calculated the average cost of living for retirees in metro areas across the U.S.

We assumed the $1 million would grow at a net annual return of 2% after inflation. Then, we divided $1 million by the sum of each of those annual numbers to determine how long $1 million would cover retirement expenses in each of the cities in our study. Cities where $1 million lasted the longest ranked the highest in the study.
