About Us


Spectrum Medical Group was formed in 1996 as a result of a merger amongst Northeast Anesthesia Professional Association, Maine Pathology Associates and Radiology Associates of Maine. The physicians of these groups recognized both the opportunity and necessity for physicians to play a leadership role in Maine's evolving managed care environment. The physicians of these three practices believed that a well-organized, integrated, physician-led organization could form the backbone of Maine's emerging integrated delivery systems and could provide high quality, comprehensive, medical services that would best meet the needs of patients, employers, insurers, other physicians, managed care organizations and healthcare systems. Their efforts resulted in the formation of Spectrum Medical Group.

Today, Spectrum is Maine's largest multi-specialty, physician owned and directed professional organization and is comprised of over 200 physicians practicing in the areas of anesthesiology, medical rehabilitation, orthopaedics, pain management, pathology, radiology, radiation oncology, and surgery. Spectrum provides services at many of Maine's hospitals throughout the state and in eastern New Hampshire.


We provide patients with innovative, cutting-edge therapies as well as access to promising clinical trials.

Anesthesiologists Spectrum anesthesiologists are skilled in the administration of all types of anesthesia, including cardiac, pediatric, neurosurgical and obstetric anesthesia and regulate critical life functions during surgery and in the intensive care unit. Anesthesiologists specializing in pain management offer innovative treatments for chronic pain conditions post surgery and trauma.

Orthopaedists  On April 1, 2014 OA Centers for Orthopaedics (OA) joined Spectrum Medical Group to form the orthopaedic division. Our multidisciplinary team offers a wide range of subspecialty orthopaedic care and provides the highest quality surgical and nonsurgical treatment of musculoskeletal conditions, injuries, and illnesses. Our highly specialized physicians are experienced in the latest diagnostic techniques and treatment options available. With more than 130,000 patient visits annually, our orthopaedics group is the largest in Maine.  OA has four orthopaedic practices in Portland, Windham, Saco, and Brunswick, with physical therapy services at all four locations. OA also includes an ambulatory surgical center, an MRI center, and the OA Performance Center.

Pathologists Our pathologists are subspecialized in anatomic and clinical pathology. Through our own rigorous peer review, we have set the standard for surgical and cytological diagnostic work and have brought important ancillary techniques to the Maine community, including advanced immunohistochemistry and molecular pathology.

Physiatrists  Our medical rehabilitation and physical medicine specialists offer a broad range of electrodiagnostics and pain management services.  Their expertise includes interventional pain procedures, comprehensive management of acute and chronic pain, electrophysiologic testing, and diagnosis and management of sports injuries not requiring surgery.  They serve as integral members of a patient's care team and work closely with primary care providers to create effective care plans that patients are able to follow.

Radiation Oncologists Our radiation oncologists provide over 30,000 services each year and provide exceptional care to a broad range of cancer patients by offering access to the most advanced and specialized procedures.  Our radiation oncologists continue to participate in research through ten active national and in-house protocols, conduct weekly peer-review, and promote a collaborative approach to patient care.  Investigational protocols are available through radiation therapy and pediatric oncology groups in correlation with the National Cancer Institute.

Radiologists Spectrum radiologists provide a wide range of interventional and diagnostic radiology services.  The division is comprised of over 55 physicians with diverse areas of expertise and subspecialization.  Primary areas of service include interventional radiology, in which physicians utilize image-guided, minimally invasive procedures to treat patients; and diagnostic radiology, in which physicians interpret images such as MRIs, ultrasounds, and CT scans to diagnose patient conditions.  The division has recently added many new services including radioactive seed localization (RSL), Y-90 for metastatic colorectal cancer, and interventional spine procedures. 

Surgery  Our surgeons provide general surgery services, with a strong focus on thyroid and parathyroid surgeries  Minimally invasive techniques are typically employed for thyroid/parathyroid, gastric reflux/diaphragmataic hernias, ventral/incisional/inguinal hernias, gallbladder, solid organ, small and large bowel resection, breast, and skin lesions.  Our focus is on minimally invasive procedures and we collaborate closely with area specialists.

Quality Improvement

As a physician-directed entity, Spectrum's coordinated physician efforts have resulted in strong patient advocacy by fostering approaches to medical care based on sound clinical data as well as cost considerations. Spectrum's Quality Committee (QC) reports directly to the practice's Board of Directors. The QC provides leadership for all Spectrum quality improvement activities. To monitor our quality and effectiveness, we carefully assess patient and physician satisfaction and conduct outcome measurements as well as utilization review.

Spectrum is organized as a professional services corporation in the State of Maine.  It is governed by a Board of Directors whose representatives are selected, in part, by its operating divisions and, in part, by the shareholders at large.  Presently, Spectrum has ten operating divisions each which elects a board director / managing director.  Spectrum also has three at large directors which are elected by all of the shareholders.  Board directors serve on staggered, three year terms.  Managing directors preside over the Divisional Advisory Committee and Practice Management meetings.
