Thank you for your interest in the Pediatric Hematology Oncology & Blood and Marrow Transplantation (BMT) Fellowship at Cleveland Clinic Children’s. Established in 2004 and accredited by the Accreditation Council of Graduate Medical Education (ACGME), our three-year fellowship program provides an outstanding opportunity for future pediatric hematologist-oncologists to learn to diagnose and treat a broad range of common and rare blood disorders and cancer. Starting July 2021, our program now accepts 2 fellows per year. Fellows will benefit from the knowledge and mentorship of our robust faculty consisting of 15 members with diverse backgrounds and interests. The care of children with cancer and blood disease is truly a team effort, and our fellows will also learn from close work with colleagues from other medical and surgical disciplines, as well as nurse-practitioners, social work, nursing and many other members of the team. Our goal is to train future leaders in the field of pediatric hematology/oncology and BMT.

This video was taken before the COVID-19 pandemic. We now follow protocols (including social distancing and masking) to protect our patients and caregivers.

Located at Cleveland Clinic main campus, the Pediatric Hematology-Oncology & BMT Department plays a significant role in promoting the outstanding recognition of this world-renowned tertiary referral center. Cleveland Clinic Children’s is a national leader in clinical care, as recognized by U.S. News & World Report's “Best Children’s Hospitals." Our mission is to provide better care of the sick, investigation into their problems, and further education of those who serve.

First year of fellowship training will be devoted to forming strong clinical competencies in pediatric hematology, oncology and BMT. Each fellow will have seven inpatient modules (five in general hematology and oncology, and two in BMT), and a variety of outpatient rotations during their PGY-4 year. With support of the faculty, the fellow will become the primary care provider for all newly-diagnosed patients in order to be able to establish their own continuity clinic patient base. The fellows will work closely with the pediatric residents during day to day patient care in a supervisory and teaching role, to learn to be the leader of the multidisciplinary team.

During the second half of the first year the fellows will also be expected to attend the clinical research and quality assurance/patient safety meetings, and will work with the Director of Research in the Pediatric Institute, to plan for an individualized approach to research and scholarship. The second year of training will include a very comprehensive Introduction to Clinical Research course at Case Western Reserve University, where the fellows will be made familiar with fundamentals of clinical study design, epidemiology, concepts of translational research, as well as core basics of statistical analysis. With the guidance of the Scholarship Oversight Committee the fellows spend the majority of Year 2 conducting research. The clinical competencies will continue to be enhanced through taking care of the patients in the outpatient Continuity Clinic.

During the third year of training, fellows will spend a minimum of one module as a junior attending in the inpatient service. Continuity clinic will also continue throughout the third year. The remainder of the time will be devoted to research, leadership development and preparing for the next stage in the fellow’s career. Fellows are expected to present results of their research during the Pediatric Institute Research Day.

The learning experience is further strengthened with the recurring didactic lectures and webinars, board question as well as standard of care protocol reviews moderated by the program faculty members. The fellows will also learn to perform all diagnostic and therapeutic procedures on their patients throughout the fellowship training.

There is no career more rewarding than pediatric hematology/oncology. We are privileged to help children and their families through an extraordinarily difficult journey, and to provide cutting-edge scientifically-based care delivered with compassion and kindness. To continue to do so, we must take care of one another and thoughtfully train the next generation of physicians who will pass this legacy on in the future. We are excited to offer this wonderful opportunity for training in pediatric hematology/oncology and hematopoietic stem cell transplantation at Cleveland Clinic Children's.

“I am from Ecuador and completed my training in pediatrics, mostly in primary care in New York. During interview season, I was fascinated about the program and how well balanced it was between the clinical and academic setting. As I fellow, I feel supported by all the staff and am getting the guidance and knowledge needed to provide the best care for our patients. All of this in a humanistic environment where the family and our patients are at the center.”

Tala Haddadin, MD

Tala M. Haddadin, MD – PGY4
“My special interest in pediatric hematology-oncology is very much influenced by the type of person I consider myself. My work experience has made me realize that a pediatric hematologist-oncologist needs to possess not only depth and breadth of medical knowledge, but also an art of communication with children and an ability to understand each individual child and adjust to their changing needs, concerns and temperament. I have seen the wonderful staff at Cleveland Clinic Children's dealing with all kinds of oncology cases, offering me a new knowledge and giving me the opportunity to encounter a vast range of clinical complexities, ranging from the most common benign hematology to the most complex syndromes and rare tumors a child can present with. A specialty that matches my passion toward the essence of hope in life. With that being said, I found my place where I can have a balance of research and clinical training that will guide me towards my career goals!”

Nikki Agarwal, MD

"In my short career in pediatrics, the most challenging and the most rewarding experience was amongst taking care of patients diagnosed with hematological issues and other malignancies. It sparked an interest in me to pursue hematology and oncology. During my rotation at Cleveland Clinic, I realized the professional yet humane approach of everyone here involved in taking care of children diagnosed with cancer. In addition to this, the collaboration between the scientists and the clinicians here gives me an opportunity to learn and participate in 'bench to bedside' and hopefully make a difference in this world. I think Cleveland Clinic is the perfect institute for me to learn the nuances of the trade and provide me with the opportunity to grow, not only as a physician but as an academician and above all, as a human."

"Applying to the Clinic and having the opportunity to interview was a rewarding experience. I chose Pediatric Hematology-Oncology as my specialty to develop the skills to best empower an already resilient parent-child dyad in the face of adversity. It was apparent from my interview day how everyone at the Clinic were supportive and working in a team to make a difference. It was also exciting to note that as a professional in training, you are encouraged to create your niche with the involvement in scholarly activity and availability of resources to pursue research. As I start my fellowship and move from an essentially primary care setting after residency in New York; I am thrilled to join the family at the Clinic, find my feet and explore the city of Cleveland as I make it my new home."

"In my time with the Cleveland Clinic, I have had a very positive and promising experience. My mentors are very inspiring and they have always encouraged and supported me. Fellows are given the autonomy to make decisions while at the same time, I can reach out to any of my faculty members at any time. My training has been designed in a way that would benefit me the most and my input is valued. The fellowship program is very flexible and adaptable to individual goals while ensuring adequate training in the core curriculum. The amount of patient exposure I have had has been very good, with well-balanced distribution of hematology and oncology patients. The ancillary staff here is exceptionally good and efficient in their work. As I am acquiring more knowledge academically, I believe the nurses and nurse practitioners have been crucial in helping me get through day to day practical aspects of work. I am hopeful and confident about my future in the field of pediatric hematology and oncology, with the guidance and training at this institute."

"I was drawn to the Cleveland Clinic Children's hospital for my hematology oncology fellowship because of the caregivers. Everyone at Cleveland Clinic is committed to fellow education and excellent patient care. I was given appropriate amount of clinical responsibilities (procedures, determining and administering protocols) and educational opportunities (education conferences, resident and medical student teaching) to balance my time and advance my career without undue stress. With strong residency program and excellent faculty and nursing staff, Cleveland Clinic provided me the very foundation I needed to mature as a clinician and educator. Cleveland is a great place to live with all major sports teams, arts and culture."

"I went to medical school at Northeast Ohio Medical University. During my second year of medical school I had the opportunity to meet a pediatric hematology/oncology physician at Cleveland Clinic Children's. I was privileged enough to shadow within the department through my remaining years of medical school. Because of this experience, Cleveland Clinic Children's was my top choice for pediatric residency. Through my residency, my love for pediatric hematology/oncology was further solidified. When I was given the opportunity to stay at Cleveland Clinic Children's for my fellowship, I jumped at the opportunity. I am very happy with my choice because my attendings, other fellows, nurses, and support staff have become my second family. The education and mentorship through Cleveland Clinic Children's has prepared me well for my current position as an Adolescent and Young Adult Oncology advanced fellow at Children's Hospital Los Angeles and for my future career."
