Kathy Hill, NP
Primary Care Practitioner (PCP)
Kathy is a Patina Primary Care Practitioner. She leads care for her patients and works with Patina’s Nurse Champions and Health Champions to ensure her patients are receiving the convenient, personalized experience they want. Kathy enjoys having the opportunity to bring care to her patients where they are – whether it’s in-person or virtually. She enjoys spending valuable time with her patients and getting to know their values, goals, and preferences for the way they want to experience their healthcare and aging journey.
Those discussions are one of Kathy’s favorite parts of the job, as it helps her guide her patients and develop healthcare plans that are personalized to them. That’s why Kathy joined Patina. She understands that healthcare tends to plant itself front and center in our lives, rather than mold itself to fit our lives. At Patina, she has the opportunity to tune care to her patients. As Kathy says, “We want to know what ‘living’ really means to you!”
Kathy studied nursing at Neumann University and earned her MSN/NP, with a focus in geriatrics, from the University of Pennsylvania. An avid runner in her free time, Kathy has completed an astonishing 15 marathons (and counting!). She also enjoys traveling and spending time with her friends and family – especially her grandchildren.

Katie Maceyko, NP
Primary Care Practitioner (PCP)
Katie is a Primary Care Practitioner at Patina. She provides care to her patients and works collaboratively with her patients’ care team to comprehensively support their healthcare and aging journey. Katie is energized by caring for her patients. She joined Patina because she believes all older adults should receive primary care that is focused on the whole person.
Katie, who graduated from Jefferson School of Nursing, believes primary care is built on meaningful, long-lasting relationships with her patients and their loved ones. Prior to becoming a nurse practitioner, Katie studied the bio-psycho-social model of health, which focuses on all of the factors that contribute to health. She partners with her patients to help them understand their health and ways to stay healthy, and then builds a comprehensive care plan that reflects their values, goals and preferences.
Katie has lived in West Philly and Center City, but her family has fallen in love with South Philly, where they currently reside. She says they were drawn to South Philly for the diversity, sense of community, proximity to city attractions, and of course, the food. In her free time, Katie enjoys cooking and baking, spending time with her family and friends and exploring the city.
Katie’s Favorite Quote: “Knowing what must be done does away with fear.” – Rosa Parks
Alexandra Ristow, MD
Lead Primary Care Practitioner (PCP)
Dr. Ristow is the Lead Primary Care Practitioner at Patina. She serves as added support for the Health Champions, Nurse Champions, and Primary Care Practitioners who make up her patients’ core care team. She oversees all care at a high level, and is part of patient care in complex situations or when coordination with specialists and hospital teams is needed. With a bachelor’s degree in biology from Claremont McKenna College, Dr. Ristow earned her Doctor of Medicine at the Yale University School of Medicine, and completed her internal medicine residency program at the University of California, San Francisco.
Dr. Ristow believes high-quality care is working together with patients in equal partnership. She brings medical expertise to the table, but her patients bring vital knowledge of their own experience, values and goals. She says that throughout her career, she has been seeking a place to practice primary care in the way she knows it should be practiced – as part of a team that truly listens to each patient and treats them as leaders of their own care. That’s why Dr. Ristow joined Patina. Her goal is to learn what matters most to her patients, and to partner with them to ensure their care empowers them to live the life they want to lead.
In her free time, Dr. Ristow enjoys spending time in the parks and green space in her community just outside of Philadelphia on the Mainline. She loves the community feeling of each individual downtown. Dr. Ristow is an avid reader, and she loves to hike and explore new places.

Michelle Lu, NP
Primary Care Practitioner (PCP)
Michelle is a Primary Care Practitioner at Patina, where she cares directly for her patients while leading a collaborative care team that includes Nurse Champions and Health Champions. Michelle works hand-in-hand with her patients to identify their values, goals and preferences, which in turn allows them to lead in their own care. As a Primary Care Practitioner, Michelle values honesty and transparency. She encourages her patients to tell her exactly “as it is” rather than what they think she wants to hear – an approach that allows Michelle and her patients to make the best decisions together about their care journey.
Michelle has a unique perspective on what it means to age gracefully and with dignity, as she was raised by her grandparents while her own parents were in school. She joined Patina because she believes that exceptional care is based on trust and individual choice, and her goal is to use her clinical training and compassion to support her patients in making the best decisions for their health and well-being. Michelle trained at the University of Pennsylvania School of Nursing, where she earned her MSN and BSN. She is also a licensed Adult-Gerontology Primary Care Nurse Practitioner (A-GNP) and Certified Professional in Healthcare Quality (CPHQ).
Whether she’s running, hiking, or having a picnic, Michelle prefers to be outdoors in the sun. In her free time, she loves learning new skills and working with her hands, including everything from patching drywall to crocheting and sewing. She lives in Delaware County, where she loves being able to choose between going into town for food and community or driving to nearby parks and hiking with her family and their dog.

Neil Patel, MD
Primary Care Practitioner & Chief Health Officer
(PCP & CHO)
Dr. Neil Patel is Patina’s Chief Health Officer, and has been a family doctor for nearly two decades. He guides Patina’s team of Primary Care Practitioners, Nurse Champions and Health Champions and ensures they have everything they need to give patients the healthcare and aging experience they deserve.
Dr. Neil, as his patients affectionately call him, joined Patina because he believes in taking the lead from his patients, honoring their expertise and wisdom and guiding them through the experience of aging. These beliefs have inspired Patina’s mission to create a new kind of primary care for adults 65 and over, one that completely reimagines the aging experience by prioritizing patients’ values, goals and preferences.
Dr. Neil graduated from Rutgers Medical School and completed his residency in family medicine at Boston University. He understands the importance of humility in the practice of medicine. In his eyes, healthcare is a gateway to helping people heal or age as confident leaders of their own journey. Patina’s care team is here to build that gateway for older adults, giving them greater strength in leading their own care.
Prior to joining Patina, Dr. Neil helped found a number of organizations, each of which aimed to improve primary care for people across the country. A father of three children, Dr. Neil enjoys spending time with his family.

Patina Nurse Champion
Nina is a Patina Nurse Champion — or, in her words, a “jack of all trades.” Nina’s role is to work closely with her patients’ Primary Care Practitioner and Health Champion to make sure they get the care they need. Nina does everything from having important discussions with patients about preventive care and wellness to helping families through confusing or critical healthcare events. Nina was fortunate enough to grow up in the same home as her maternal grandparents and right next door to her paternal grandparents. She says their own healthcare experiences deeply impacted her, and motivated her to pursue a career in healthcare and join Patina.
A graduate of SUNY Purchase College and Frankford Hospital School of Nursing, Nina approaches patient care the way she would want someone to care for her family and loved ones, and strives to ensure her patients know she is always in their corner. Before becoming a nurse, Nina received her undergraduate degree in literature, which is perhaps one reason why she loves taking time to listen to the stories her patients share with her.
In her free time, Nina likes to go on long runs, travel and spend time with her husband and their dog. Nina lives in Philadelphia, where she loves to spend time with her tight-knit community. Her neighborhood, she says, is the kind of block where you can knock on someone’s door for a cup of sugar or a few eggs.
