Dr. Simmi Smrita Singh, MD is an Internal Medicine physician dedicated to patient-centered, evidence-based primary care for adults. A native of the Washington, DC metropolitan area, Dr. Singh earned her medical degree from Howard University College of Medicine and a Master of Public Health from The George Washington University, before completing her Internal Medicine residency at HonorHealth Scottsdale Thompson Peak Medical Center in Arizona. Her training spans the full breadth of adult medicine — from busy outpatient primary care panels to inpatient care across five hospital campuses — with advanced elective training in Geriatrics and Hematology-Oncology at the Mayo Clinic.
Dr. Singh’s practice centers on prevention, chronic disease management, and the long-term physician-patient relationships that make both possible. She has particular expertise in managing hypertension, diabetes, and COPD; a special interest in women’s health — recognized with a 2nd place award at the Arizona American College of Physicians conference for her quality improvement work raising breast cancer screening completion rates; and a deep commitment to comprehensive geriatric care. Having grown up in the DMV and now living in Fairfax, Dr. Singh is proud to return home to care for the community that raised her.
Dr. Singh is accepting new patients at Prima Medicine’s Fairfax and Merrifield offices.
Full-Scope Internal Medicine, Built on Prevention
Dr. Singh believes the best medicine happens before illness takes hold. With her combined MD and Master of Public Health training, she approaches every patient with two lenses: what does this person need today, and what will keep them healthy for decades?
Her practice includes:
- Annual physicals and preventive health visits
- Evidence-based chronic disease management — hypertension, diabetes, COPD, high cholesterol
- Age-appropriate cancer screenings, tracked and followed through to completion
- Vaccinations and immunization guidance
- Evaluation and treatment of new and ongoing symptoms
- Patient education and counseling that makes complex medicine understandable
- Telemedicine visits for convenient follow-up care
Patients describe visits with Dr. Singh as unhurried and genuinely collaborative — she listens first, explains clearly, and builds treatment plans patients can actually live with.
A Champion for Women’s Health
Women’s health is one of Dr. Singh’s defining clinical passions — and her approach goes beyond the exam room. She provides well-woman visits, Pap smears and cervical cancer screening, contraception counseling, and preventive care tailored to each stage of a woman’s life.
Her distinctive strength is making sure preventive screenings actually happen. As a resident physician, Dr. Singh designed and led a quality improvement initiative to raise breast cancer screening completion rates across her patient panel — work that earned 2nd place for Best Quality Improvement Presentation at the Arizona chapter of the American College of Physicians. In practice, this means Dr. Singh doesn’t simply recommend a screening and move on: she tracks whether it actually gets done, follows up on results, and makes sure abnormal findings never fall through the cracks.
For women in Fairfax and Merrifield, that translates into a primary care physician who treats screening as a commitment, not a checkbox:
- Personalized breast cancer screening plans based on age, family history, and risk factors
- Screening coordination and completion follow-through
- Careful follow-up of results, with clear explanation of what they mean
- Cervical cancer screening and HPV prevention
- Coordination with specialists when additional evaluation is needed
Comprehensive Geriatric Care
Dr. Singh has a special interest in caring for older adults, strengthened by advanced elective training in Geriatrics at the Mayo Clinic and additional experience in palliative care. She understands that medicine for seniors is different: multiple conditions interact, medication lists grow, and goals of care matter as much as lab values.
Her geriatric care includes:
- Medicare Annual Wellness Visits
- Management of multiple chronic conditions in coordination
- Thoughtful medication review to reduce unnecessary prescriptions
- Cognitive and memory concerns — screening and early evaluation
- Fall prevention, mobility, and independence planning
- Compassionate conversations about goals of care, involving family when patients wish
Hospital-Trained Depth for Complex Conditions
During residency, Dr. Singh managed inpatient panels across five HonorHealth hospital campuses in the Scottsdale and Phoenix region, alongside her outpatient continuity practice. She strengthened that foundation with elective training in Hematology and Oncology at the Mayo Clinic, plus rheumatology and palliative care experience.
That hospital-level experience shows in the office: Dr. Singh recognizes early warning signs, knows when a symptom warrants urgent attention versus reassurance, and coordinates confidently with specialists when advanced care is needed — keeping her patients informed at every step.
A Career Rooted in Service and Science
Dr. Singh’s path to Prima Medicine reflects an unusual combination of research rigor and community commitment:
- National Institutes of Health / National Cancer Institute — cancer research through the NCI’s Comparative Oncology Program
- Massachusetts Eye and Ear / Harvard-affiliated research — anatomic modeling research supporting development of a novel hearing-restoration approach
- Free clinic service at Howard University — years of volunteer care for uninsured and underserved patients in Washington, DC, including work to expand cancer screening and diagnostic follow-up
- Community health outreach in Baltimore — connecting disadvantaged families with health insurance, housing, food, and employment resources
- Recognized for over 300 hours of community service with honors including an American Red Cross Volunteer of the Year Award (National Capital Area)
This background shaped a physician who meets every patient with cultural competence, patience, and respect — and who believes high-quality care should feel accessible to everyone.
A DMV Native, Home in Fairfax

For her patients, that means a physician who isn’t just practicing in Northern Virginia — she’s invested in it, for the long term. Dr. Singh joined Prima Medicine seeking a permanent professional home where she can care for the same patients and families throughout her career.
