Programs
The mission of the Periwinkle Arts in Medicine (PAIM) program at Texas Children's Cancer and Hematology Center (TCH) is to provide enjoyable and educational art activities that give children, young adults, families, and caregivers affected by pediatric cancer and blood disorders the opportunity for self-expression, empowerment, and healing through the arts. Established in 1997, the Arts in Medicine program at TCH is integral to the Center's commitment to providing comprehensive care in a child-centered environment that meets patients' emotional, social, educational, and medical needs.See Schedule OThrough partnerships with more than 10 local artists and arts organizations, PAIM connects the community's vibrant arts scene with patients and their families who are enduring hours, if not days, weeks, or months of a grueling hospital routine to provide daily opportunities for art experiences in the outpatient clinic, the inpatient unit, and the Bone Marrow Transplant unit at bedside.

$505,332 spent34% of program spendingCamp Periwinkle - Since 1983, The Periwinkle Foundation, celebrating its 42nd Anniversary, has provided a week-long camp for children with cancer and blood disorders, as well as their siblings. Periwinkle brought 134 campers, ages 7 to 15, to Camp Periwinkle in 2024. Campers came from diverse ethnic and socio-economic backgrounds. Many would not have the means to attend a summer camp even if they were well. Periwinkle provides clothing, bedding, and toiletries for any camper in need. Sad faces turned bright in a week packed with a month's worth of amazing experiences. With the help of more than 86 enthusiastic volunteers, cancer was forgotten, children realized they were not alone in their circumstances, siblings felt loved, and parents had an entire week to address their emotional healing.
$519,903 spent35% of program spendingCamp YOLO - In its 26th year, Camp YOLO (You Only Live Once) addresses the unique challenges faced by adolescents living with cancer, renal, cardiac, rheumatology, or HIV-related illnesses. While most teens worry about how many text messages they can send, teens with serious illnesses confront genuine life-and-death issues and seemingly unending hospital routines. For two weekends each year, these young people can rejuvenate with others who understand their struggles, anxieties, and fears. Campers learn teamwork and leadership skills, and by the end of a fun-packed and emotion-filled weekend, they leave knowing they are not alone and have what it takes to keep fighting their illness. Over 186 campers attended the April/September camp sessions, along with approximately 101 dedicated volunteers each session.
$230,200 spent16% of program spendingLong-Term Survivor - In 2024, Periwinkle's Long-Term Survivor program featured a weekend retreat, providing opportunities for young adult survivors to come together, share experiences, learn life skills, and give back to the cancer community. It also included monthly socials for cancer survivors, providing emotional, social, and professional support. Over 114 survivors had encounters through these life-enhancing opportunities. Twenty-eight Long Term Survivors volunteered as camp counselors in 2024.Family Camp held in April/September for Houston Families and in November for families at the Vannie Cook Cancer Clinic in McAllen, TX, welcomed 27 families with a newly diagnosed child to get away from the hospital routine, forget about their child's illness, create cherished family memories and meet other families who understand the stresses they are experiencing due to a child's cancer diagnosis.Periwinkle Day Camp, an inner-city week-long camp for patients aged 7-12, welcomed 46 campers for a magical week of camp in the city. This program enables campers who may not be able to participate in our overnight camps due to medical needs to have an incredible camping experience.

The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2022 to 2023, from $2.6M to $2.0M (−20%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2021 7%. Grants only. Government contracts and fees sit inside program revenue.
100% of The Periwinkle Foundation’s revenue is contributions — more reliant on donations than three-quarters of its peers (82% for the typical peer).

Who funds it, year by year
2017 → 2023: the base broadened from 19 funders to 34 funders, grant income rose $145k → $701k.
17 of 90 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 18% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of The Periwinkle Foundation’s funders (the co-funder graph). Top 30 of 90 funders by total. Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How concentrated its funding is
The Periwinkle Foundation has a broad base — no single funder exceeds 23% of grant income, and it takes 7 funders to reach half.
the vertical line marks half of all grant income — 7 funders to its left
40% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund The Periwinkle Foundation.
Largest funder’s share by year: 2017 24% · 2018 14% · 2019 18% · 2020 36% · 2021 31% · 2022 26% · 2023 29% — growing more concentrated.
“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
51% of The Periwinkle Foundation's funders are still giving 3 years after their first grant; 63% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
92% of The Periwinkle Foundation's grant income comes from Texas funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $810k arriving through sponsors registered in 13 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
Against its field
The Periwinkle Foundation's funding base is broadening — from 19 funders to 34 as grant income climbed.
