Patient Care & Clinical Services

Our infectious disease specialists provide consult services to Seattle Cancer Care Alliance (SCCA) patients. Clinical services are provided at both inpatient (University of Washington Medical Center) and outpatient settings (SCCA outpatient facility located on the Fred Hutch campus).

IDS faculty physicians pursue a team approach to providing exceptional patient care, working closely with hematologists and oncologists on individual treatment plans for patients. Our researcher physicians also oversee critical quality-improvement initiatives related to infectious diseases, including the development of standard practice guidelines and other clinical care guidelines in infection control and antibiotics management.

Our Patient Services Include:

  • Partnering with hematologists and oncologists on treatment plans
  • Overseeing quality exercises related to infectious diseases
  • Developing standard practices and guidelines in infection prevention and control
  • Conducting pre-transplant evaluations
  • Managing patient follow-up visits, including antibiotics management
  • Creating long-term follow-up plans

Patient appointments are limited to current SCCA patients and require a referral from your SCCA primary provider.

Our faculty work at the interface of patient care and scientific discovery.

In partnership with the patient and a multidisciplinary team, our clinicians strive to provide the highest quality care. As leaders of clinical research and trials, IDS faculty advance scientific knowledge to improve treatment and prevention of the infectious diseases that afflict our patients.

Joshua Schiffer, M.D., M.Sc.

Dr. Schiffer is interested in describing the quantitative and dynamic features of human pathogens and immune responses.

Lisa So, P.A.-C

So enjoys working and providing care for people of all ages and backgrounds. She brings her molecular biology education as well as her bone marrow transplant service experience to provide care for her patients.

Anna Wald, M.D., M.P.H.

Dr. Wald is interested in epidemiology, natural history, therapy and prevention of HSV and other herpesvirus infections, including the interactions between HSV and HIV.


Leah Yoke, P.A.-C

As a physician assistant, Yoke’s goal is to create a space where patients and their loved ones feel comfortable enough to honestly discuss their goals of care from an Infectious Disease standpoint. She strives to provide evidence-based, compassionate, unbiased care for every patient she sees.

Debra Mattson (Retired)

As a physician assistant, Mattson provided care with kindness and respect while having a thorough knowledge of the patient’s infectious disease issues.
