Serena Williams Is Now One of the Most Visible Faces of GLP-1 Care

Celebrity partnerships are nothing new in healthcare marketing.

But Ro’s partnership with Serena Williams is more strategically useful than putting a recognizable athlete next to a product.

Williams is a 23-time Grand Slam singles champion who spent decades training at the highest level of professional sport. Her public identity is built around discipline, fitness, physical performance, and consistency.

That makes her weight-loss story especially useful for a GLP-1 company.

After having children, Williams has said that she continued exercising and eating well but struggled to lose the weight she wanted to lose. She eventually began GLP-1 treatment and partnered with Ro in 2025 to talk publicly about that experience.

Ro then expanded the partnership in 2026 with its Healthier on Ro campaign, including the company's first Super Bowl commercial.

The marketing lesson isn't simply that celebrity endorsements get attention.

It's that the right spokesperson can answer an objection before the company has to explain it.

Serena’s Story Directly Challenges the Willpower Objection

One of the most persistent assumptions around weight loss is that people who struggle simply aren't exercising enough, eating correctly, or trying hard enough.

Serena Williams makes that argument difficult to sustain.

This is someone whose career required extraordinary physical discipline. She competed at the highest level of professional tennis for decades, yet still described struggling with her weight after pregnancy despite training and eating well.

That's exactly why her story is useful to Ro.

It reframes the conversation from personal discipline to medical treatment.

And that framing is consistent with how obesity is increasingly understood clinically. Obesity isn't simply the result of poor willpower. Genetics, hormones, stress, sleep, medications, environment, eating patterns, and other factors can all influence body weight.

Ro doesn't need a long explanation of that biology at the beginning of the campaign.

Serena's history communicates the point immediately.

If an elite athlete can need additional medical support, then needing treatment doesn't automatically mean someone failed to work hard enough.

That's a much stronger marketing argument than simply telling consumers to stop feeling guilty.

‍

The Campaign Expands the Story Beyond Weight Loss

Another smart part of Ro's strategy is that the campaign doesn't make the scale the entire story.

In its 2026 Super Bowl campaign, Ro reported that Williams had lost 34 pounds over a year while using GLP-1 treatment. But the creative also highlighted stable blood sugar, reduced pressure on her knees after weight loss, and improvements in cholesterol.

That matters because weight-loss advertising can easily become cosmetic.

Ro is deliberately positioning treatment within a broader health story.

Instead of presenting the desired outcome as simply becoming thinner, the campaign connects weight loss to movement, metabolic health, and how Serena feels physically.

That gives potential patients more than one reason to care.

Someone may enter because they're frustrated with their weight. Another person may be worried about mobility. Another may be thinking about metabolic health or the long-term consequences of obesity.

The campaign gives all of those consumers a place in the story.

There is an important marketing distinction here, though. Serena's individual health outcomes are her own results. Telehealth brands using patient stories need to be careful not to imply that every patient should expect the same weight loss or health changes.

That becomes especially important when the spokesperson is one of the most famous athletes in the world.

‍

Ro Connects Awareness Directly to Care

A celebrity campaign becomes much more valuable when the advertiser can capture the demand it creates.

Ro can.

Someone who sees Serena's campaign doesn't have to remember the brand, search for a doctor weeks later, and figure out how to access treatment independently.

Ro can move that consumer directly into its own care experience.

A prospective patient can learn about treatment, complete an online evaluation, connect with a licensed provider, and, if clinically appropriate, receive a prescription and ongoing support.

That means the advertising and the healthcare delivery system are connected.

This is one reason the campaign is different from a traditional pharmaceutical awareness campaign.

Ro isn't only helping create interest in GLP-1 treatment. It has built the infrastructure to convert that interest into an actual patient relationship.

For telehealth companies, that's the bigger lesson.

Awareness matters much more when the path from interest to care is short and obvious.

‍

The Celebrity Is Doing a Specific Job in the Funnel

A weak celebrity partnership begins with fame. A stronger one begins with the customer objection.

Ro's creative uses Williams to address questions potential patients may already have before they visit the website.

The first is straightforward: Why can't I just work harder?

Serena's background answers that naturally. Few consumers are going to argue that one of the most accomplished athletes in history simply needed more discipline.

The second question is: Is GLP-1 treatment only about looking thinner?

Ro expands her story into weight, metabolic health, mobility, and overall wellbeing.

That changes what Serena is doing in the campaign.

She isn't simply generating impressions.

She's helping resolve skepticism.

‍

Step 1: Choose Spokespeople Based on the Objection They Can Remove

Healthcare brands often select ambassadors based on audience size, cultural relevance, or how much attention they'll generate.

Those things matter, but they're incomplete criteria.

Ask a more useful question:

What does this person's story make easier for the customer to believe?

For Ro, Williams can credibly talk about discipline because her career proves it.

A spokesperson for a menopause platform might be valuable because she can normalize a life stage patients feel uncomfortable discussing. A patient ambassador for a hair-loss company might help address embarrassment. A recognizable athlete recovering from an injury could make rehabilitation treatment feel more acceptable.

The spokesperson should solve a communication problem.

Fame alone doesn't do that.

Step 2: Connect the Personal Story to the Medical Problem

A celebrity's story gets attention because it's personal.

But healthcare marketing still has to connect that story to accurate medical information.

Ro's Williams campaign works because the personal experience supports a broader message that weight management can involve biology and medical treatment, rather than being framed entirely as a failure of discipline.

That idea has support well beyond Ro's advertising.

Current obesity research describes the disease as the result of complex biological, behavioral, environmental, and genetic factors. The CDC also describes obesity as a complex chronic disease and explicitly warns against reducing it to a lack of willpower.

That gives the campaign something stronger than an emotional story.

The story reinforces a medically grounded idea.

For health brands, that's the standard to aim for. The spokesperson creates relevance, but the underlying message still needs evidence.

Step 3: Give People Somewhere to Go After the Story

Attention without a clear next step wastes much of the value created by the campaign.

Ro's advantage is that the company owns much of the customer journey.

A consumer can encounter Serena in an ad and then move directly toward evaluating whether GLP-1 treatment is appropriate for them.

Telehealth brands should think about the entire path:

- What does the person see immediately after clicking?

- Does the landing page continue the same message as the ad?

- Can they understand eligibility without digging through the website?

I- s pricing clear?

- How quickly can they complete an evaluation?

- What happens if they're interested but not ready to start treatment immediately?

A high-profile spokesperson can increase traffic dramatically.

If the funnel creates confusion after the click, the brand has simply paid more money to expose the problem to more people.

Step 4: Turn One Story Into Multiple Reasons to Care

Ro could have built the entire campaign around pounds lost. It didn't.

Weight is the easiest outcome to communicate, but the campaign also discusses blood sugar, cholesterol, joint stress, energy, and Williams' broader health.

That gives the creative more depth and creates additional messaging opportunities.

The same principle applies to other telehealth categories.

A hormone company shouldn't talk exclusively about one lab result. A sleep platform shouldn't only sell more hours asleep. A metabolic health brand shouldn't reduce its value to a number on the scale.

Start with the most obvious consumer problem, then show how treatment connects to the wider health experience.

That creates a stronger reason to continue care after the initial problem improves.

Step 5: Make the Commercial Relationship Clear

Celebrity healthcare marketing also comes with a higher standard for transparency.

The FTC requires endorsements to reflect the endorser's genuine experience and says material relationships that could affect how consumers interpret an endorsement should be disclosed.

Ro identifies Serena Williams as a celebrity patient ambassador and also discloses another relationship that consumers may consider relevant: her husband is an investor in Ro and serves on its board.

Healthcare companies are asking consumers to trust information that can influence medical decisions. Trying to hide the commercial relationship undermines the credibility the spokesperson was supposed to create.

The goal isn't to make an endorsement look completely independent - it's to make the relationship transparent enough that people can evaluate it for themselves.

Celebrity Health Marketing Has to Do More Than Create Reach

Serena Williams gives Ro enormous visibility, but reach alone isn't the interesting part of this campaign.

The campaign connects several things at once: a recognizable patient, a common objection, a broader health message, and a direct path into care.

That's what makes the strategy useful for other telehealth brands.

You don't necessarily need Serena Williams - you need someone whose real story makes your customer's hardest question easier to answer.

The person could be a celebrity, physician, athlete, creator, or existing patient. What matters is that their role in the campaign is clear.

If they're only there because people recognize their face, you're buying attention. If their experience helps a consumer understand why the treatment exists and who it might help, you're doing something more valuable.

Final Take

Ro didn't choose Serena Williams simply to make GLP-1 treatment famous.

GLP-1s were already famous.

Her value is that her story addresses the stigma surrounding who needs medical weight-loss treatment and why.

She trained harder than almost anyone. She still described reaching a point where diet and exercise weren't producing the result she wanted after having children. That gives Ro a powerful way to challenge the idea that seeking treatment means someone lacked discipline.

The campaign then goes one step further by connecting that story directly to Ro's telehealth experience.

That's the lesson for healthcare marketers.

Choose spokespeople who don't just attract attention. Choose people whose story answers the objection standing between the patient and care.
