Mission and programs · 2024

Mission

To provide outstanding mental health and support services.

  • Parkside, Inc. provides quality mental health services regardless of race, creed, sex, national origin, handicap, age, or ability to pay. Although reimbursement for services rendered is critical to the operation and stability of Parkside, Inc., it is recognized that not all individuals possess the ability to purchase essential mental health services and further, that our mission is to serve the community with respect to providing mental health services and mental health education. Therefore, Parkside, Inc. provides care to persons covered by government programs at below cost, and mental health care activities and programs to support the community will be considered when the need and/or individual's ability to pay exists. These activities include community education programs and a variety of broad community support activities. Parkside, Inc. provides care to persons covered by governmental programs. Recognizing its mission to the community, services are provided to both Medicare and Medicaid patients. Pakside, Inc. also provides services to those who are unable to pay. These charity care services are unreimbursed to the hospital. Charity care is also provided through many reduced price services and free programs offered throughout the year based on activities and services which Parkside, Inc. believes will serve a legitimate community health need.

The first 25 listed. Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. A Schedule J breakdown is as filed: base pay, bonus, other, deferred compensation and nontaxable benefits from this organization, with any from related organizations beside each, and the filer's own total. It is shown with the Part VII listing of the same name on the same return. The form gives no key between the two, so that pairing is ours, and is marked matched by us. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.

Grants made

No itemized grants to organizations. Schedule I is filed only by organizations that granted more than $5,000 to a recipient, so most filers have none.

Grants received

The 10 largest by cash amount. The API serves every itemized grant.

Related organizations

From Schedule R Part II, where a filer lists the tax-exempt organizations it is related to by control. It does not record shared board members or money.

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 13 October 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
