For several decades, Associates in Radiation Medicine has been the region's trusted physician group for advanced, compassionate radiation therapy — embedded within leading hospitals and cancer centers across Maryland and Delaware, right in your community.
Your Community. Your Care Team. We believe expert cancer care should be accessible close to home. Our physicians are embedded in community hospitals and cancer centers across Maryland and Delaware, so your care fits into your life.
"We became radiation oncologists because we believe that exceptional cancer care should be personal, not just technical. Every patient who walks through our doors is someone's parent, spouse, child, or friend. We never take that lightly.
Each of us trained at leading academic medical centers across the country. We chose to bring that expertise here — to the hospitals and communities of Maryland and Delaware — because we believe our neighbors deserve the same quality of care, without having to travel far from home.
If you're facing a diagnosis, or if you're a physician caring for someone who might benefit from radiation, we want you to know: we are accessible, we communicate, and we are here for you. Please reach out to us directly."
Associates in Radiation Medicine (ARM) is a group of highly trained, board-certified radiation oncologists who have trained and practiced at top academic cancer centers and leading institutions across the country. We bring that depth of expertise to regional hospitals and cancer centers across the Greater D.C. metro area, Maryland, and Delaware, delivered with the warmth and personal attention of a community practice.
We work in close partnership with major academic and regional health systems, including the University of Maryland, MedStar Health, Luminis Health, CalvertHealth, and TidalHealth. These collaborations ensure our patients benefit from the full resources of established institutions, while still receiving their care close to home from a team they know and trust.
We serve a wide region of Maryland and Delaware — at the hospitals and cancer centers already familiar and accessible to you.
We know a diagnosis can be overwhelming. Our entire team — physicians, nurses, therapists, and physicists — is here for you, every step of the way.
Our partnerships with major regional health systems mean our patients benefit from institutional resources, multidisciplinary expertise, and coordinated care.
Our radiation oncology programs are accredited by the American College of Radiology (ACR) — a rigorous national standard for quality, safety, and patient care excellence.
Radiation oncology is a team endeavor. ARM physicians work alongside a highly skilled, dedicated group of professionals who are as invested in our patients as the doctors themselves. All members of our nursing, therapy, and physics staff have worked in this region for years, some for decades — and many live right here in the communities where they practice.
That continuity matters. When you walk through our doors, you're not starting over with a new face each visit. You're returning to people who know you, who remember your story, and who genuinely care about how you're doing — people who are invested in your recovery.
Board-certified physicians who specialize in the use of radiation to treat cancer and select benign conditions. They lead your care plan, coordinate with your broader oncology team, and are available to you throughout treatment.
Our registered nurses provide compassionate, expert support from your first visit onward — monitoring your health, managing side effects, answering your questions, and making sure you always feel heard and cared for.
Certified radiation therapists are the skilled professionals who deliver your daily treatments. With careful precision and a warm presence, they ensure each session is administered accurately, safely, and with your comfort in mind.
Our dosimetrists are specialists in designing the precise radiation dose plans that guide each patient's treatment. Working closely with physicians and physicists, they ensure radiation is shaped and distributed with exacting accuracy.
Our board-certified medical physicists work behind the scenes to verify treatment plans and calibrate equipment with exceptional precision — ensuring that the radiation delivered is exactly what was intended, every single time.
Our radiation oncologists are highly trained specialists who have trained and practiced at leading academic cancer centers across the country. They bring that expertise home to the communities of Maryland and Delaware.
ARM physicians are embedded within — and work in close collaboration with — some of Maryland and Delaware's most respected hospital networks and health systems. These partnerships allow us to deliver coordinated, multidisciplinary cancer care that draws on the full strength of each institution, while remaining accessible and personal for our patients.
Our physicians and physicists are trained in the most current and effective radiation techniques. We offer the same treatment sophistication available at any major cancer center — delivered with the accessibility, warmth, and personal attention that make a real difference during treatment.
Treatment plans that evolve with the patient — using repeat imaging to adjust for changes in tumor size, shape, or position over the course of treatment, ensuring maximum accuracy from the first session to the last.
Computer-controlled beams modulate radiation intensity in three dimensions for precise, conformal treatment. VMAT delivers this rotating continuously around the patient, reducing treatment time while maintaining exceptional accuracy.
Ultra-precise, high-dose radiation delivered in just one to five sessions — effective for tumors of the brain, lung, liver, spine, and other sites. You may have heard this called SABR (Stereotactic Ablative Radiotherapy), SRS, or by machine brand names such as CyberKnife® — these all refer to the same category of highly targeted treatment we provide.
Real-time and pre-treatment imaging ensures that each treatment is delivered with exceptional accuracy, accounting for patient positioning and internal organ motion. Our programs utilize advanced technologies including:
Radiation delivered from within or immediately adjacent to the tumor using radioactive seeds or applicators. Commonly used for prostate and gynecologic cancers, brachytherapy delivers a high dose directly to the target while minimizing exposure to surrounding tissue.
Targeted radioactive molecules that seek out and destroy cancer cells with exceptional precision. We are excited to offer Pluvicto (lutetium Lu 177 vipivotide tetraxetan), a breakthrough treatment for metastatic castration-resistant prostate cancer. We are actively preparing to make this cutting-edge therapy available to our patients beginning mid-2027.
Radiation therapy is not only for cancer. ARM physicians are trained and experienced in using low-dose radiation therapy (LDRT) to treat certain non-cancerous conditions — a specialized service that many practices do not offer.
For patients with select benign conditions which have led to chronic pain and have not responded to other treatments, LDRT can offer meaningful and long-lasting relief, often with minimal side effects. We take a careful, evidence-based approach to every evaluation.
LDRT has demonstrated meaningful pain and inflammation reduction in joints affected by osteoarthritis — including the knee, hip, and shoulder.
LDRT can provide significant and lasting pain relief for patients with chronic plantar fasciitis who have not responded to conventional treatments such as physical therapy, orthotics, or injections.
Radiation therapy can slow or halt progression of this fibrous tissue disorder of the hand, helping patients preserve hand function before contracture develops.
Radiation following surgical removal of keloids significantly reduces the likelihood of recurrence, improving both cosmetic and functional outcomes.
Radiation therapy for benign conditions is a highly specialized area of practice that many centers do not offer. ARM physicians bring this expertise directly to community cancer centers across our region.
If you or your referring physician are curious whether radiation might help a non-cancerous condition, we welcome a consultation.

No. You won't feel anything during the treatment itself — radiation is silent and invisible. Some patients experience mild skin sensitivity or fatigue over the course of treatment, but many continue working and their normal daily routines throughout.
Most daily sessions take 15–30 minutes from arrival to departure. The actual delivery of radiation typically takes just a few minutes — the rest is setup and verification. Most patients drive themselves to their appointments.
Hair loss from radiation only occurs at the area being treated — and only if that area has hair. Unlike chemotherapy, radiation does not cause generalized hair loss. Your care team will discuss any expected effects specific to your treatment site.
Yes, in most cases. Radiation therapy doesn't involve sedation, so most patients drive themselves to daily sessions. If fatigue becomes an issue during your course of treatment, we'll help you plan accordingly.
