Amalia Geller, MD

I have a passion for neurology and sleep medicine. I have a vision for developing post-stroke care programs and incorporating sleep medicine screening in this setting. Sleep apnea is considered the 3rd leading risk factor for stroke, independent of hypertension, diabetes and atrial fibrillation. PERSONAL STATEMENT I have been in the health care field since I was 18 years old as a respiratory therapist. My career path took me through pharmacy school and then to medical school. During my education years I worked as a pharmacist and have real work experience in the private sector. This has helped me to develop managerial and administrative skills. I am happily married / 19 years and am blessed to have a wonderful husband who has seen me through this career as a physician. We are blessed with 2 children, now teenagers who are also thinking of careers in the health care field. I cherish my time with my family and pets and enjoy yoga, spinning and pilates. Keeping up with current issues in my chosen field is also an essential part of how I spend my time.
