Donna Sicuranza, now listed professionally as Donna Sicuranza Marconi, is an American nonprofit leader best known for her decades of work with Tait’s Every Animal Matters, usually called TEAM. Unlike many names that become popular through movies or celebrity families, Donna became known through animal welfare. She helped develop a mobile feline clinic that has grown from a small experiment in 1997 into a statewide Connecticut program whose veterinarians have now sterilized and vaccinated more than 225,000 cats.
Her story is also one that needs careful research. Several people named Donna Sicuranza appear in online records, and some websites have accidentally combined their biographies.
The Donna discussed here is the Connecticut nonprofit executive connected with TEAM—not Donna Marie Sicuranza, the New York banking professional who died in 2017.
So who is Donna Sicuranza, how did she become involved with animal welfare, and why has a mobile veterinary clinic become the defining work of her career?

Who Is Donna Sicuranza?
Donna Sicuranza is a nonprofit executive whose public career has centered on improving access to veterinary care for cats.
Her organization, Tait’s Every Animal Matters, operates a mobile feline spay/neuter and vaccination clinic in Connecticut.
Why Is She Known in Animal Welfare?
Donna’s name is closely connected with the creation and long-term operation of that mobile program.
TEAM says most of its core staff have worked with the program for more than 25 years. Its veterinarians have sterilized and vaccinated over 225,000 domestic and feral cats since the clinic began operating in 1997.
That number makes Donna’s story less about personal celebrity and more about measurable community impact.
One cat at a time, the work added up.
Donna Sicuranza’s Early Life
This is one area where reliable public information becomes limited.
Donna has spent much of her public life discussing animal welfare rather than her childhood, family background or personal milestones.
Her Birth Date Is Not Reliably Confirmed
Some websites give exact ages or dates of birth for Donna Sicuranza.
The problem is that several people share the name.
One particularly common mistake is using details belonging to Donna Marie Sicuranza, a different woman from New York who worked in banking and died in 2017.
Those details should not be transferred to Donna Sicuranza of TEAM.
A responsible biography therefore has to leave Donna’s exact age open unless stronger first-party documentation appears.
Donna Sicuranza and Tait’s Every Animal Matters
Donna’s professional identity is inseparable from TEAM.
Tait’s Every Animal Matters is a nonprofit charity based in Westbrook, Connecticut.
Its main mobile program focuses on making feline sterilization and vaccinations easier to access for Connecticut residents.
Why Was TEAM Needed?
Before affordable spay/neuter programs became easier to find, many cat owners and people caring for feral colonies struggled to pay for surgery.
TEAM says this contributed to unwanted litters, overcrowded shelters, abandoned animals and other welfare problems.
The organization decided that prevention offered a practical answer.
Instead of waiting for thousands of kittens to be born and then trying to find homes for all of them, reduce unwanted births in the first place.
That idea became the foundation of the mobile clinic.
The Mobile Clinic Began With an Unusual Idea
Planning for TEAM’s mobile feline clinic began in 1996.
Donna worked alongside veterinarian Dr. John A. Caltabiano, who was then TEAM’s president.
Their plan was straightforward but ambitious.
Bring the veterinary clinic closer to the people who needed it.
The First Clinic Day
The mobile unit went on the road on March 1, 1997.
TEAM’s own historical account says ten cats were sterilized and vaccinated on that first day.
Within six months, the clinic had sterilized approximately 5,000 cats. By its first anniversary, the total had reached around 8,000.
That growth showed there was enormous demand.
What started as a small mobile clinic quickly became something much larger.
Why a Mobile Cat Clinic Was Different
A traditional veterinary hospital stays in one location.
A mobile clinic travels.
That sounds like a simple difference, but it can matter greatly for people with limited transportation, residents in rural areas or caretakers trying to manage groups of feral cats.
Bringing Services Into Communities
TEAM’s modern clinic continues to travel to communities throughout Connecticut.
Its services are open to domestic and feral cats belonging to or cared for by Connecticut residents.
That mobility became one of the organization’s biggest strengths.
The clinic could go where the demand was instead of expecting every person to travel long distances to find affordable treatment.
Donna Sicuranza and John Caltabiano
Dr. John A. Caltabiano is one of the most important people in Donna’s professional and personal story.
They worked together closely on TEAM.
But their connection went beyond nonprofit work.
They Were Longtime Partners
When Caltabiano died in November 2009, published obituaries identified Donna Sicuranza of Westbrook as his longtime partner.
That gives their TEAM story a more personal dimension.
They were not simply two professionals working on the same project.
Animal welfare had become part of the life they shared.
Who Was Dr. John Caltabiano?
Caltabiano was a veterinarian who devoted a significant portion of his work to animal population control.
He helped establish the TEAM Mobile Feline Unit and was involved in other approaches aimed at reducing feral-cat overpopulation.
By the time he died, TEAM had already sterilized more than 128,000 cats, according to his obituary.
Donna continued the work after losing him.
Continuing TEAM After John Caltabiano’s Death
The death of a founder can create a difficult moment for any organization.
Does the work continue?
Does leadership change direction?
Does the project slowly disappear?
In TEAM’s case, the mission continued.
Connecticut Department of Agriculture material published after Caltabiano’s death discussed his contributions to animal population control, while Donna remained associated with continuing the programs they had developed.
Years later, TEAM is still operating.
That continuity may be one of the strongest parts of Donna’s professional legacy.
Donna Became a Long-Term Executive Director
Donna was not given the title of Executive Director recently.
Her leadership stretches back decades.
TEAM’s own history identifies her as Executive Director during the planning of the mobile clinic in 1996.
By 2019, organizational publications were still listing her in that role.
And in 2026, TEAM’s current staff page still identifies Donna Sicuranza Marconi as Executive Director.
That represents roughly three decades of involvement with the same mission.
TEAM Has Now Helped More Than 225,000 Cats
Numbers can make nonprofit work easier to understand.
TEAM currently says its veterinarians have sterilized and vaccinated more than 225,000 cats since 1997.
Why Spaying and Neutering Matters
One unsterilized cat can eventually contribute to many litters.
Those kittens may then reproduce too.
Over time, populations can grow far faster than shelters and rescuers can manage.
Spaying and neutering interrupts that cycle.
TEAM’s model therefore focuses heavily on prevention rather than waiting until animals are already abandoned or homeless.
For Donna, that prevention-first approach has remained central for decades.
The Clinic Serves Both Pet Cats and Feral Cats
TEAM does not work only with family pets.
Its services also include feral cats.
That is particularly important because feral colonies can be difficult to manage using ordinary pet-care systems.
Helping Cat Caretakers
People caring for outdoor or feral cats may have multiple animals needing sterilization.
The cost of taking them individually to conventional clinics can become too high.
Mobile and lower-cost services create another option.
Connecticut’s own pet-owner resource materials continue to list the TEAM Mobile Feline Unit among available lower-cost veterinary services for domestic and feral cats.
Donna Sicuranza’s Work Reached State-Level Discussions
Donna’s work has not stayed entirely inside the nonprofit.
She has also participated in broader Connecticut conversations about animal population control.
Connecticut Department of Agriculture Working Group
In August 2019, Connecticut Department of Agriculture meeting records listed Donna Sicuranza — Tait’s Every Animal Matters among attendees at an Animal Population Control Program Working Group meeting.
The meeting addressed issues including veterinary costs, reimbursements, licensing and the future of animal-population-control programs.
Donna was not listed as a government employee.
She was there representing TEAM.
That distinction matters.
Her role was to bring nonprofit animal-welfare experience into a broader policy discussion.
Is Donna Sicuranza a Veterinarian?
No.
Donna is the organization’s Executive Director.
Veterinary procedures are performed by licensed veterinary professionals.
TEAM’s current staff page separately lists its medical director and veterinary technicians.
What Does an Executive Director Do?
Running an animal-welfare nonprofit involves far more than caring about cats.
Someone has to coordinate programs, staff, schedules, fundraising, public communication, community relationships and long-term planning.
A mobile veterinary clinic also creates extra challenges.
The vehicle needs equipment.
Appointments must be coordinated.
Medical staff need supplies.
Communities need schedules.
Donors need to understand where their money goes.
Donna’s public role has sat at the center of that system.
Donna Sicuranza or Donna Sicuranza Marconi?
Readers may notice that current sources sometimes use a longer name.
TEAM’s current page identifies her as Donna Sicuranza Marconi.
Older documents generally say Donna Sicuranza or Donna J. Sicuranza.
Are They the Same Person?
The organizational continuity strongly indicates that the names refer to the same TEAM executive.
The role, organization and professional history line up across the older and current records.
However, there is no need to invent a personal explanation for when or why the surname Marconi was added unless Donna herself or another reliable source documents it.
That private detail can remain private.
Is Donna Sicuranza Married?
This is another question where internet biographies often become too confident.
The best-documented personal relationship in reliable historical sources is Donna’s longtime partnership with Dr. John Caltabiano, who died in 2009.
Current TEAM materials use the surname Sicuranza Marconi.
But a surname alone is not enough to build an entire marriage biography with a wedding date and family story.
For that reason, her current marital history should not be filled in with guesses.
Is Donna Sicuranza the Woman Who Died in 2017?
No.
This confusion appears frequently online.
Another woman named Donna Marie Sicuranza lived in New York, had a career in banking and died in 2017.
That is not the same person as Donna Sicuranza Marconi, who is currently listed by TEAM as its Executive Director.
Why the Confusion Matters
Mixing the two women can create a completely false biography.
A wrong birth date gets added.
Then a wrong husband.
Then a banking career.
Then a death date.
Soon an article looks detailed but is actually describing two different people.
The easiest way to keep the identities separate is to remember the professional trail.
Donna Sicuranza Marconi = TEAM, Westbrook, Connecticut, animal welfare.
What Is Donna Sicuranza’s Net Worth?
There is no verified public figure for Donna’s personal net worth.
She is a nonprofit executive rather than a celebrity whose finances are routinely discussed in business publications.
Websites that provide an exact number are therefore likely estimating.
An estimate should not be presented as a confirmed financial fact.
Her public legacy is much easier to measure through TEAM’s work than through a guessed dollar amount.
What Is Donna Sicuranza Doing in 2026?
The clearest answer comes from TEAM itself.
Its current staff directory still lists Donna Sicuranza Marconi as Executive Director.
TEAM also reports that the mobile clinic remains active and continues traveling through Connecticut.
That means the project Donna helped build in the 1990s is still operating nearly three decades later.
Why Is Donna Sicuranza Being Searched Online?
Donna is not an actress or reality television personality.
Yet interest in her name has grown online.
Part of that interest comes from people researching TEAM.
Another part comes from confusion created by different biographies using the same name.
But the strongest reason her story deserves attention is simple.
The work has lasted.
A nonprofit clinic that started with ten cats on its first day has now treated hundreds of thousands.
That is the kind of result that makes someone worth writing about even without Hollywood fame.
Donna Sicuranza’s Legacy Is Really TEAM’s Legacy
Some biographies are built around awards.
Others are built around hit movies or famous marriages.
Donna’s story is easier to understand through an animal entering a mobile clinic.
A caretaker arrives with a cat.
The cat receives sterilization and vaccinations.
The caretaker takes the animal home.
There is no unwanted litter later.
Repeat that process tens of thousands of times and the effect becomes enormous.
That is what makes TEAM’s reported figure of more than 225,000 cats so meaningful.
Final Thoughts
Donna Sicuranza has spent decades working on a problem that does not always make national headlines: feline overpopulation.
In 1996, she and veterinarian Dr. John A. Caltabiano helped plan a mobile veterinary program.
The following March, the clinic went onto Connecticut roads.
Only ten cats were treated on the first day.
The experiment could easily have disappeared.
Instead, it grew.
TEAM now says its veterinarians have sterilized and vaccinated more than 225,000 cats, and the nonprofit’s current staff page still lists Donna Sicuranza Marconi as Executive Director.
Her story also contains personal loss. Caltabiano, her longtime partner and professional collaborator, died in 2009.
Yet TEAM continued.
In 2026, Donna’s most meaningful biography is therefore not found in an estimated net worth, an invented birthday or celebrity gossip.
It is found in nearly three decades of work that made veterinary care easier to reach for Connecticut cat owners and caretakers.
