Dr. Lee draws from both his experience and his continuing education in hospice and palliative medicine as he works to help other physicians and patients’ families who are supporting patients faced with life-threatening diseases or who are dealing with severe symptoms from their diseases.


Sabiha Pasha, MD, ABIM

American Board of Internal Medicine, Hospice and Palliative Medicine, American Board of Integrative Holistic Medicine

Dr. Pasha has been in practice for 22 years the majority of it walking the halls in a hospital. When patients get admitted to a hospital they are at their most scared and vulnerable. Often they are left alone to traverse the complexity of their illness with confusing treatment choices while at the same time managing their ever meager resources. Some die without a soul to witness their passing. In 2005 I was introduced to palliative care. It promised to restore autonomy and dignity to the chronic and seriously ill. To focuses on quality of life as defined uniquely by the patient. To support the family even while ameliorating pain and other uncomfortable symptoms. It was exactly what my patients needed. As it turns out, the training and certification was exactly what I needed. Palliative care catapulted me onto a path of self- discovery, compassion and resiliency. Every day I am a witness to fear and courage. And I have learned to be still and just be present. Ultimately, suffering is a part of life and having someone to hold your hand even for a moment can ease the pain. Palliative care is not rocket science, but it is the one last bastion where the art of healing lives on.

Dr. Sister received his education and medical degree from Ryazan State Medical University.  He began his medical practice as an Internist, but a few years later, after relocating to Israel, he became interested in Geriatrics.  Caring for seniors, overseeing their well being and aging process and understanding the challenges of dementia became a special focus and passion for Dr. Sister.

After finishing his residency in Geriatrics and receiving a Masters Degree in Geriatrics from Sacler Medical School of the Tel Aviv University, Dr. Sister became head of the Geriatric Department and served as a Geriatric Fellowship Director of the Safed Hospital.  After moving to the United States, Dr. Sister continued his training, completing a residency in Internal Medicine and a Fellowship in Geriatrics. While practicing geriatrics he first became aware of the evolving medical specialty of palliative care. 

Combining all his years of medical experience and medical knowledge in helping patients and their families make decisions about what care they want and clarifying what is important to them, palliative care became a natural part of his practice.


Kathleen Mackessy, RN, FNP

Kathleen Mackessy has 17 years of nursing experience which includes critical care and trauma, medical, surgical, home health, and wound care.  Kathleen followed a progressive leadership training from the bedside to a supervisory and then management position where she managed 200 nurses and hospital staff.  While Kathleen loved the management experience and the learning, she felt something was missing.  It was the one on one patient experience that makes being a nurse such and honor.

She went back to school at California State University San Marcos and received her Master’s Degree as a Family Nurse Practitioner in 2018.  She is certified by the American Association of Nurse Practitioners.  Her dedication to serving patients with chronic illness is what brought her to this position.  “I am honored to be allowed to be a part of this time in their livers.  It is important to me to get to know them and to find out what gives them joy.  Although illness and death is the most difficult time in one’s life, it can be a time of discovery and it is my goal to aide in making patients and family ready for this transition.  We palliate symptoms of illness, often this is just the beginning of what we do as palliative care providers.  We offer hope, comfort, and compassion and meet our patients and families where they are on their journey.  Caring for patients and their families during illness is sacred and I am blessed to be invited to share this journey with them”.

Edward holds a Bachelor of Science Degree from the University of Toledo and a Masters Degree as an Adult/Geriatric Nurse Practitioner. He is board certified by the American Academy of Nurse Practitioners. Edward was drawn to palliative care by the holistic approach to relieving suffering and the opportunity to establish close relationships with patients and their families as they face a difficult time in their lives. I relish the ability to provide patients autonomy in their health care decisions.
