Aisha Abdul- Samad, M.S., CCC/SLP

Aisha started her professional career after obtaining her Bachelor’s of Science degree in Psychology in 1998. After her undergraduate degree, she landed an entry level position as a clinical assistant on an inpatient neurobehavioral unit in Baltimore providing direct care to children with Autism Spectrum Disorders (ASD)/developmental disabilities. While implementing clinical protocols on this unit, it was evident that many of the patient’s behaviors were linked to their inability to effectively communicate their basic needs. Observing the speech therapists’ role in facilitating functional communication and addressing feeding/swallowing impairments, Aisha was inspired to pursue a career in Speech Language Pathology.

 Aisha went on to complete a second bachelor’s degree and ultimately a Master’s of Science degree in Speech Language Pathology at Towson University in 2004. Her externships consisted of a placement at a 243 bed teaching hospital in downtown Baltimore as well as a special needs program at a school in Baltimore County. Her post graduate fellowship was completed at a rural hospital in Pennsylvania providing services to both children and adults ranging from infants to geriatrics within a variety of settings including acute, subacute, home health, early intervention, and outpatient environments. 

 After completing her fellowship, Aisha became certified by the American Speech and Hearing Association and has worked as a medical speech language pathologist since 2004. The majority of her caseload has consisted of adults with acute neurological,cardiopulmonary, and gastrointestinal diseases who have speech, cognitive communication, and/or swallowing disorders. Her functional based and client focused approach to therapy has been center in her delivery of the highest standards of care. Aisha also utilizes the most updated therapeutic tools in her service delivery, which includes the use of IPAD software for speech/language stimulation, neuromuscular electrical stimulation (NMES) in the treatment of adults with swallowing disorders, and instrumental swallow evaluations using Modified Barium Swallow (MBS) studies. Aisha has been VitalStim certified to provide NMES since 2013 and has had 12 years of experience performing MBS studies in coordination with area hospital radiology departments.  She currently provides flexible hours of services at a Level III hospital where she performs bedside evaluations on the critical care/stroke units as well as performs MBS studies in order to stay abreast of current healthcare trends. 

 Aside from acute care, Aisha also enjoys the challenge of working with chronically ill geriatrics in subacute/long term care facilities. She is passionate about helping patients with declining cognitive and swallowing abilities to maintain the highest level of independence possible. She has completed dementia training and cultural sensitivity courses which enhance her bedside relationships. Aisha has spent her career teaming with families, dietitians, physicians, social workers, and therapists to help in discharge planning and the end of life decision-making process. 

 Although the majority of her career as a speech language pathologist has been with adults, Aisha still adores working with children with special needs.  She has a combined total of 3 years experience delivering pediatric services including two years at an outpatient clinic and a year with early intervention programs. She enjoys working on developing pre-feeding skills, language expansion, and social skills through play. She has used concepts from her background in applied behavioral psychology to encourage the child’s motivation to participate in therapy and reduce maladaptive behaviors that limit treatment progress. She believes wholeheartedly in a family centered and inter-discipline approach to both evaluation and treatment. During her early years working with children in rural Pennsylvania, one of Aisha’s biggest satisfactions was her partnership with occupational and physical therapists to plan and develop the facility’s first sensory integration camp.

 When not seeing patients, Aisha enjoys spending time with her family, dining out, attending cultural events, and singing/dancing around the house to streaming music.
