  • About

    Physician Bio

    Stephen Catalya, MD, joined Washington Township Medical Foundation in August
    2020. As an internal medicine specialist with a special focus on infectious
    disease, he certainly picked a compelling time to become part of the team.

    “My training and experience have indeed led me to an extremely important
    moment in health care,” said Dr. Catalya, who most recently was
    an infectious disease fellow and consulting physician at four hospitals
    in the Mt. Sinai Hospital System in New York City––a place
    many have called the epicenter of America's coronavirus pandemic.

    Besides being at the forefront of COVID-19, the physician-researcher has
    extensive experience in skin/soft tissue infections, malaria/travel medicine,
    tuberculosis/nontuberculosis mycobacterial infections, endovascular infections,
    central nervous system infections, and HIV/AIDS. “I like to focus
    not just on diagnosis and treatment for my patients,” said Dr. Catalya,
    “but also on their continuity of care and health care management.”

    A Bay Area native who grew up in Walnut Creek, Dr. Catalya is happy to
    be part of the Fremont community––a diverse, multicultural
    environment that’s a perfect fit. “I’m passionate about
    ensuring comprehensive treatment, both inpatient and outpatient, for all
    populations,” said Dr. Catalya, who likes to unwind through watching
    sports, daily exercise workouts, fine dining, watching movies, and time
    with family.

    “I truly believe in the Washington Township Medical Foundation approach
    to multidisciplinary care,” said Dr. Catalya, who embraces the synergy
    and collaboration of so many specialties in one organization. “Our
    internal medicine team is committed to comprehensive treatment plans for
    our patients. This means that, when necessary, we can work with providers
    in cardiology, oncology, nephrology, pulmonology, intensive care and more.”

    For all patients, communication is key. “From the moment a patient
    comes to see me, I want to completely understand what is going on and
    what their concerns are,” Dr. Catalya explained. “It’s
    critical that together we can evaluate all possible options and treatment
    and come up with a plan. The goal is to do the right thing for each individual.
    And when we see them do well and there’s a smile on their face,
    then we’ve done our job.”
