More questions →What Is the NDSS Buddy Walk and Where Does It Take Place?
The NDSS Buddy Walk® is the National Down Syndrome Society's flagship awareness and fundraising event, and the organization's own site highlights an NYC edition that puts 500+ faces of people with Down syndrome on display in Times Square. If you want to participate, donate, or find a walk near you, the event details and registration live on ndss.org — the site lists the NYC Buddy Walk® as a featured event, but it does not publish a full national schedule on the page reviewed here, so you should check the site directly for dates and locations beyond New York.
What the Buddy Walk Is
The Buddy Walk is an NDSS event built around two goals:
- Awareness — celebrating and increasing visibility for individuals with Down syndrome.
- Fundraising — raising money that supports NDSS programs and its mission, stated on the site as "to create a world where individuals with Down syndrome thrive."
It is a community event rather than a competitive race, which is why it centers on participation and visibility rather than times or placements.
The NYC Buddy Walk and Times Square Visibility
According to the NDSS homepage, the National Down Syndrome Society Buddy Walk® "to Highlight 500+ faces in Times Square." This means the NYC event is used as a high-visibility moment: images of more than 500 individuals with Down syndrome are featured in one of the most heavily trafficked public spaces in the world.
That detail matters for two reasons:
- Scale of awareness — Times Square placement reaches far beyond the people physically at the walk.
- Focus on individuals — the "500+ faces" framing keeps the spotlight on people with Down syndrome themselves, consistent with NDSS's stated mission.
Where It Takes Place
The page reviewed confirms the NDSS NYC Buddy Walk® as a named event. Beyond that, the site does not list a complete set of host cities or dates in the content available here.
To find a specific walk:
- Go to ndss.org and look for the Buddy Walk® section or event listings.
- Check the site's newsroom and "All the Latest" area, which is where NDSS posts event-related announcements.
- If you cannot find a local walk, use the contact channels below to ask.
How to Get Involved
| Goal | Where to start |
|---|---|
| Join or find a walk | Buddy Walk® listings on ndss.org |
| Donate or fundraise | Event pages linked from ndss.org |
| Ask about a specific city or date | NDSS contact channels on the site |
| Follow event announcements | NDSS social media (Facebook, X, Instagram, YouTube, LinkedIn, TikTok) |
Other Ways NDSS Suggests Supporting the Mission
The homepage also describes non-event giving options, which may suit you if a walk is not near you or not at a convenient time:
- Everyday purchases — NDSS partners with Upside, described as a free cash back app that rewards purchases at gas stations, grocery stores, and restaurants. You can choose to donate your earned cash back to NDSS.
- Team NDSS in Paris — NDSS fields a charity team for Paris races, with applications listed for the Hoka Semi De Paris Half Marathon (March 7, 2027) and the Schneider Electric De Paris Full Marathon (April 11, 2027).
Contact and Location Details
- National Down Syndrome Society
- 1155 15th Street NW, Suite 540, Washington, DC 20005
- Toll-free NDSS Helpline: 800-221-4602
- Hours: Mon–Fri, 9AM–5PM ET
If your main question is a specific Buddy Walk date or city, the helpline or the event listings on ndss.org are the most direct ways to confirm it, since the homepage content alone does not carry a full schedule.
How to Support NDSS Through Everyday Purchases and Events
You can support the National Down Syndrome Society (NDSS) in several ways that don't require writing a separate check: donating cash-back rewards through the Upside app, joining Team NDSS for a marathon, buying gear from the NDSS Shop, or taking part in a Buddy Walk. Each route has different time, cost, and effort requirements, so the right one depends on whether you want to give money passively, fundraise actively, or show up in person.
Donate everyday cash back through the Upside app
NDSS partners with Upside, described on its site as a free cash back app that rewards you for everyday purchases at gas stations, grocery stores, and restaurants. When you earn cash back through Upside, you can choose to donate those rewards to help individuals with Down syndrome thrive.
How it works:
- Sign up for Upside and make purchases at participating gas stations, grocery stores, or restaurants.
- Earn cash back on those purchases.
- When redeeming your rewards, select NDSS as the recipient of your donation.
What to expect: This is the lowest-effort option because it redirects money you were already spending on routine purchases. The trade-off is that the amount depends entirely on how much you buy through participating merchants, so it's better suited to ongoing, passive support than to hitting a specific fundraising target.
Join Team NDSS for a marathon
NDSS fields a team for marathon events, including races in Paris. The site lists these application windows:
| Event | Date | Application |
|---|---|---|
| Hoka Semi De Paris Half Marathon | March 7, 2027 | Apply for the Half Marathon |
| Schneider Electric De Paris Full Marathon | April 11, 2027 | Apply for the Full Marathon |
Both are framed as running "to help create a world where individuals with Down syndrome thrive." If you're considering this route, note that it involves travel to Paris, a training commitment for a half or full marathon, and an application process rather than open registration — apply through the links on the NDSS site for the distance you want.
Shop for NDSS gear
The NDSS site includes a Shop section for NDSS Gear. Buying branded merchandise is a straightforward way to support the organization while getting something in return, and it works as a one-time action rather than an ongoing commitment. Check the Shop page directly for current items and any details on how purchases support the mission.
Take part in a Buddy Walk
The NDSS Buddy Walk® is the organization's flagship fundraising and awareness event. The site highlights an NDSS NYC Buddy Walk® and notes that the Buddy Walk® will "highlight 500+ faces in Times Square." Buddy Walks combine fundraising with community visibility, so they suit people who want to participate in person, raise money through a team, and help raise awareness at the same time. Look for a walk near you or the NYC event if you want the highest-visibility option.
Which option fits you
- Want to give with no extra spending or time? Use the Upside app and route your cash back to NDSS.
- Want a physical challenge and a fundraising goal? Apply for Team NDSS in Paris for the half or full marathon.
- Want something simple and tangible? Buy gear from the NDSS Shop.
- Want to fundraise and build community locally? Join or organize around a Buddy Walk.
Other ways to stay connected
NDSS maintains a Newsroom with press releases and policy statements, and its site links to Facebook, X, Instagram, YouTube, LinkedIn, and TikTok. For direct questions, the NDSS Helpline is toll-free at 800-221-4602, and the office is reachable Monday–Friday, 9AM–5PM ET at 1155 15th Street NW, Suite 540, Washington, DC 20005.
What Down syndrome resources and support does NDSS offer?
The National Down Syndrome Society (NDSS) is a US-based nonprofit whose stated mission is "to create a world where individuals with Down syndrome thrive." Its website, ndss.org, functions as a hub for three kinds of things: information about Down syndrome, direct support channels (including a toll-free helpline), and ways to participate — from advocacy and policy updates to community events and fundraising. If you are a parent, self-advocate, educator, or supporter looking for a starting point, the site's navigation and footer point you to each of these areas.
Information and resources
The site's main navigation includes a Resources section, which is the place to look for general information about Down syndrome. The footer also lists About Down Syndrome as a separate entry, so background and explanatory material is reachable from any page rather than buried.
For current news and organizational positions, the site maintains a Newsroom with a Policy subsection. Recent items shown on the homepage include:
- An NDSS Statement on Texas v. Kennedy (policy)
- "Assume I Can: A Celebration of Artists With Down Syndrome" (press release)
- An announcement that the National Down Syndrome Society Buddy Walk® will highlight 500+ faces in Times Square (press release)
- "National Down Syndrome Society Launches MinDSet Down Syndrome" (social media)
If you need to know where NDSS stands on an issue or what it has announced recently, the Newsroom and Policy pages are the relevant entry points.
Direct support: the NDSS Helpline
The most concrete support channel listed on the site is the NDSS Helpline:
| Detail | Information |
|---|---|
| Toll-free number | 800-221-4602 |
| Hours | Monday–Friday, 9 AM – 5 PM ET |
| Mailing address | 1155 15th Street NW, Suite 540, Washington, DC 20005 |
| Contact | "Contact us" link in the footer |
The site does not describe what the helpline covers or whether any language services are available, so treat it as a general information line and confirm specifics when you call.
Community events and ways to get involved
NDSS runs and promotes participation-based events rather than only publishing information:
- NDSS NYC Buddy Walk® — listed as a homepage heading, with a related press release about highlighting 500+ faces in Times Square.
- Join Team NDSS in Paris — charity marathon entries, with applications open for:
- Hoka Semi De Paris Half Marathon — March 7, 2027
- Schneider Electric De Paris Full Marathon — April 11, 2027
- Turn Everyday Purchases into Impact — a partnership with Upside, described as a free cash back app rewarding purchases at gas stations, grocery stores, and restaurants, where earned cash back can be donated to NDSS.
These are participation routes: fundraising, awareness events, and athletic charity entries. Dates and application details are stated on the site; anything about cost, fundraising minimums, or eligibility is not given in the material available here, so check the individual event pages before applying.
Other sections worth knowing
The footer and navigation also point to Work for NDSS, Shop NDSS Gear, Financials, and Privacy Policy, plus social accounts on Facebook, X, Instagram, YouTube, LinkedIn, and TikTok. The Financials page is where to look if you want to review the organization's finances before donating.
How to choose where to start

- Need to talk to someone → NDSS Helpline, 800-221-4602, weekdays 9 AM–5 PM ET.
- Tracking advocacy or organizational positions → Newsroom → Policy.
- Want to participate or fundraise → Buddy Walk®, Team NDSS marathon entries, or the Upside donation partnership.
- Evaluating the organization before giving → Financials and the Newsroom.

Phone
| Channel | Number | Hours |
|---|---|---|
| NDSS Helpline (toll-free) | 800-221-4602 | Mon–Fri, 9AM–5PM ET |

Suite 540
Washington, DC 20005
Online
The site's footer includes a Contact us link for inquiries that aren't handled by phone or mail. Use this route when you need a written record of your message or want to reach a specific department rather than the general helpline.
Following NDSS on Social Media
NDSS lists six official channels in its footer:
- X
- YouTube
- TikTok
These are the accounts NDSS itself links to, so they're the reliable starting point if you want updates on news, events, and campaigns without going through the main website each time.
What You'll Find Beyond Contact Info
The same footer that carries the contact details also links to sections on About Down Syndrome, Work for NDSS, Resources, Shop NDSS Gear, Financials, Newsroom, and the Privacy Policy. If your reason for contacting NDSS is actually to find information, check these sections first — many common questions about Down syndrome resources and organizational policies are answered there without needing to call.
Common Questions
Is the helpline free? It's listed as a toll-free number (800 prefix), so calls within the US aren't charged by NDSS.
Can I visit the DC office? The site publishes the address for correspondence but doesn't state walk-in hours or visitor policies, so call ahead before planning a visit.
Which social platform should I use? All six are official. Pick based on how you prefer to consume updates — for example, YouTube for video content, LinkedIn for organizational and professional news, or Instagram and TikTok for shorter visual posts.
Where do I send a press inquiry? The site separates a Newsroom section from general contact, so route media requests there rather than through the helpline.
Website Overview
An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality. Page metadata, canonical configuration and social previews work together to provide more consistent search and sharing presentation.
Domain and Registration
Registered in 1996, this domain has about 30 years of history. That suggests continuity, although ownership and purpose may have changed. Transfer-protection status is present, helping reduce the risk of unauthorized domain transfers. The domain uses the common .org extension, which is not an independent safety signal.
DNS and Email
Nameservers are provided by Cloudflare, indicating managed DNS hosting. MX records point to the Microsoft 365 email service. No CNAME was found; the observed records resolve directly to addresses. SPF and DMARC are configured. DKIM status is unknown. TXT records include verification markers for Google, Apple, Microsoft. Such markers may also remain after a service stops being used.
TLS and Certificates
The certificate uses an RSA 2048-bit public key, offering broad client compatibility. The server supplied a complete certificate chain. No organization name is present in the certificate; the available fields are consistent with domain validation. The certificate was issued by Let's Encrypt, commonly associated with automated certificate services. The certificate's total validity is about 89 days, consistent with a short renewal cycle.
HTTP and Browser Security
The response lacks these common security headers: CSP, Referrer-Policy, Permissions-Policy. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. The x-cache, x-served-by, via response header indicates a CDN or caching proxy in the delivery path. No obvious internal addresses or debug information were found in the headers. The Server header identifies nginx without an exact version.
Technology Stack Analysis
The public page identifies Drupal, jQuery, Google Tag Manager, Fastly, nginx without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
Twitter Card metadata is configured. The title has 37 characters, within a common display range. A meta description is present, with 60 characters. The observed directives allow indexing and link following. No Generator meta tag is publicly exposed.
