Jackie Jacobi, M.D.

Dr. Jackie Jacobi earned her medical degree from Temple University in Philadelphia.  At Mayo Clinic in Minnesota, she completed a fellowship in clinical neurophysiology, the Neurology Residency, and the Neuromuscular Disorders (Peripheral Nerve Disorders) Fellowship. She went on to complete a third fellowship in sports neurology at Barrow Neurologic Institute in Phoenix before joining Mayo Clinic in Arizona.

Dr. Jacobi is committed to helping trainees become well-rounded neuromuscular physicians. She would like to help our trainees feel confident managing complex neuromuscular conditions, including nerve, muscle, and neuromuscular junction diseases. In addition, they will learn to do EMG and neuromuscular ultrasound.

Dr. Jacobi enjoys getting to work with trainees and getting to know them as a person and a physician. Collaborating with each other in clinic and in the EMG lab throughout the year allows us to see a trainee’s growth. As a tertiary care center, we get to see a very wide variety of pathology and approaching these complex cases as a team with our fellows makes it a great place to learn and teach!

Dr. Jacobi loves seeing how much our fellows grow and learn throughout the year. She tries to come up with a few teaching points for every patient seen. She always learns best from the patients she sees rather than what she reads in a textbook. She also tries to explain things in different ways and reiterate the important concepts.

Dr. Jacobi believes that we have so many opportunities here at Mayo that we can really tailor the fellowship to help trainees achieve their individual career goals. There is a lot of research that trainees can get involved in for those who wish to pursue academics. We also have teaching opportunities with our residents and medical students for fellows who want to build their teaching skills, trainees who want to focus on building their clinical skills have extra clinic exposure.

Dr. Jacobi loves hiking and trail running! She spends a lot of time outside of work running ultramarathons. Arizona has amazing outdoor activities!

Stephen Johnson, M.D.

Dr. Stephen Johnson completed the Neurology Residency at Mayo Clinic in Minnesota, followed by fellowship training in neuromuscular medicine and ALS clinical research at Mass General Brigham. His clinical focus within neuromuscular is ALS, and he directs the MCA ALS Multidisciplinary Clinic. Dr. Johnson’s research interests include interventional ALS clinical trials and the development of biomarkers to better monitor disease progression, therapeutic efficacy, and enhance patient quality of life.

Dr. Johnson’s commitment to our program is that education is a priority. We ensure that trainees get the most educational cases. We are also fortunate not to depend on trainees to function. This means that trainees are here to learn and not to cover a service line. We are fully committed to training the next generation of leading neuromuscular clinicians.

Dr. Johnson’s believes that Mayo Clinic is an amazing learning environment and has the resources and structure to ensure trainees receive the best training possible. Additionally, faculty are highly supportive, eager to teach, and wonderful to work with.

Mayo Clinic attracts curious, enthusiastic, and motivated individuals. Dr. Johnson believes that helping such individuals achieve their goals and mature into capable and confident neuromuscular clinicians is very rewarding.

Dr. Johnson lets trainees know that it’s always OK to ask questions. That’s the way we learn, and this is a safe, supportive environment where questions and learning are priorities.

In his free time, Dr. Johnson enjoys exploring new restaurants and outdoor activities like hiking, skiing, and wake surfing.

Mohamed Kazamel, M.B., B.Ch.

Dr. Mohamed Kazamel obtained his medical degree from the Mansoura Medical School in Egypt followed by neurology residency at Mansoura University Hospitals. He then completed his neurology residency at the University of Alabama at Birmingham (UAB) Medical Center and the Neuromuscular Medicine Fellowship at Mayo Clinic in Minnesota.

Dr. Kazamel takes his level of commitment to trainees a little bit beyond teaching and training to involve being an actual mentor to them. This would involve developing their academic skills in different scholarly activities and providing them with career development advice. The one thing he always finds rewarding about teaching is seeing our program graduates become independent neuromuscular neurologists in a practice where they develop their own style of teaching and help spread the knowledge they acquired during training.

Dr. Kazamel tries to understand early on what the trainee’s early career goals are and adjusts his focus with them based on these goals. He realizes that all trainees are going to learn the basic clinical bedside and procedural skills. However, some may need to further their academic scholarly skills like preparing a platform presentation and manuscript drafting in addition to career development and job search. It all depends on the trainee’s goals at the end of the day. In addition, he goes into the first patient room and typically introduces the trainee to the patient as my colleague and our fellow.

Dr. Kazamel likes that at Mayo Clinic we have all the facilities and equipment that would help our trainees learn a diverse set of procedural skills. This eventually increases their options when they are searching for their first job at the end of training.

Dr. Kazamel is a long-distance runner and is continuously training for a marathon race. This helped him through the years to acquire some degree of patience and natural optimism.

Sri Raghav Sista, M.B.B.S.

Dr. Sri Raghav Sista completed his neurology residency at the University of Illinois, followed by fellowship training in clinical neurophysiology at Mayo Clinic in Minnesota and neuromuscular medicine at Duke University. He began his academic career at the University of Texas Health Science Center at Houston as a neurohospitalist and neuromuscular specialist, where he was recognized with the Teacher of the Year Award in his first year for excellence in resident education. In 2024, he joined Mayo Clinic in Arizona.

Dr. Sista remains deeply committed to medical education and is actively involved in neurology residency and neuromuscular fellowship training. His clinical interests include subacute neuromuscular disorders, neuromuscular junction diseases, and inpatient neurological disorders with a strong emphasis on thoughtful clinical reasoning, evidence-based care, and mentorship.

Dr. Sista’s commitment to trainees is to provide a supportive, approachable, and rigorous learning environment. He strives to be easily accessible, easy to work with, and available whenever fellows need guidance, while emphasizing practical evidence-based clinical decision making and high-quality patient care. He is also committed to giving honest, timely, and constructive feedback to help trainees grow clinically, academically, and professionally.

For Dr. Sista, a fellow is the same as his colleagues. He tries to establish a rapport, so they are free to approach him with any issue, whether they are related to clinical training or not.  Dr. Sista partners with trainees by first understanding their individual backgrounds, strengths, and prior experiences, recognizing that no two trainees start at the same point. He then clarifies their short- and long-term career goals and tailors his guidance, clinical exposure, and feedback accordingly to help them reach those objectives.

Dr. Sista especially enjoys teaching at Mayo Clinic because of the complexity and diversity of neuromuscular disorders we see and the high caliber of our trainees. This unique combination creates an environment that allows us to demonstrate cutting-edge, evidence-based medicine and to teach best practices as they are described—and refined—in the textbooks. Teaching allows Dr. Sista to help transform motivated trainees into confident, independent specialists who deliver high-quality, evidence-based care. Being part of that growth and helping shape the next generation of neuromuscular clinicians is deeply fulfilling.

Dr. Sista trained at Mayo Clinic without planning to be close to family, but it worked out that he ended up living near his sister in Scottsdale purely by chance. He states that having his family nearby has been a great source of balance for him.
