Who We Are
Our Founder’s Philosophy
The Mission
Wings of Hope Medical Services was founded in 2018 by Dr. Ilya Katz with a mission to provide the highest quality primary care to patients who were home-bound or home-limited. Our practice helps to reduce hospitalizations and manage symptoms across all specialties, enabling better overall health and wellness for our patients.
The Vision
We are physician-led and patient-centered. Our practice focuses on all aspects of a person’s wellbeing—physical, emotional, mental and spiritual. With this foundation in place, we empower individuals and improve quality of life for both patients and their families.
Our Team
Our team is committed to supporting you every step of the way, by bringing quality healthcare directly to you.
Dr. Ilya Katz, MD
Founder, Medical Director
As a physician, I was taught that patient care should be disease-centered until I was faced with the terminal illness of my wife. Living through the pain of possible loss, I discovered that patient care must be person and family-centered.

Crystal Ramos, NP
Family Nurse Practitioner
My name is Crystal Ramos. I’m a mother of two teenagers and I have a wonderful and supportive husband. I love to hike, read novels and spend time with my family. My interest in becoming a Nurse Practitioner began since my childhood years. I spent many years volunteering for hospitals and even for Hospice of the Valley to get acquainted with this profession. My journey began by first working as a Certified Nursing Assistant followed by receiving my LPN, and then becoming a Registered Nurse.
For the past couple of years I continued my education with a Masters as a Nurse Educator and then I completed my studies with a Post-Masters as a Family Nurse Practitioner. I truly love learning, providing education and being able to further my education as an individual. Being able to provide support, comfort care, and having the opportunity to help others has always been my passion. I look forward to this new journey as a Nurse Practitioner.
Gabrielle Nesselrode, NP
Family Nurse Practitioner
My name is Gabrielle (Gabby) Nesselrode. I have been a nurse for 8 years, a Nurse Practitioner for 2.5 years. I became a Nurse Practitioner because I wanted to change continuity of care for patients and having a constant provider seeing them to provide quality care treating others as my own loved ones. I love being able to advocate for my patients, the ability to listen, comfort, and become a part of my patients life.
I love making a difference in not only my patients’ lives but their families lives as well. When I’m not working, I enjoy spending time with my husband and our 5 children- running around to extracurriculars & sports, outside playing, camping, and reading.
