Walquidia 'Wallie' Jarrell - RN

Director of Nursing

Wallie grew up in Manhattan, New York, and lived in or around Lancaster County for sixteen years.

Prior to becoming a nurse, Wallie worked as a medical assistant in a primary care setting focusing on the needs of vulnerable populations such as newly arriving immigrants, the homeless, and the working poor who are under-insured or not insured at all. This position was very humbling and opened the pathway to working with individuals who struggle with mental illness.

As a registered nurse, Wallie has worked in a variety of medical settings including inpatient hospice, hematology/oncology, homecare, inpatient psych, and orthopedics. In addition to obtaining her nursing degree from Brandywine Hospital, she has a Commercial Driver’s License to drive tractor trailers, and also holds certificates in both Mig and Tig welding.

Helping people is what she is most passionate about. Wallie is a very empathetic and compassionate person especially toward vulnerable populations such as the elderly and children. She has always had an interest in mental health and enjoys helping people discover their resiliency and inner strength. Working in a variety of settings as a staff nurse, especially during COVID and then transitioning into management has given Wallie a better understanding and appreciation for the staff she manages. She believes that the majority of nurses are dedicated, compassionate, and hard-working professionals and are in nursing simply because they care. “Caring is our driving force.”

In 10 years, Wallie hopes to be living in the mountains of Panama with her husband and their dog. She would like to volunteer her time between a dog sanctuary and orphanage.

One thing Wallie might tell a friend who was considering seeing a therapist or seeking other mental health services:

Give it a try; Invest in yourself and learn how to live your best version. Learn how to live the life you always thought was out of reach.”

I always would encourage somebody to seek help for mental health complaints. I have found that seeking therapy can help us gain awareness and new insight into things we may be dealing with.”

Trevor Williams - RN, BSN


Trevor grew up in Ohio and moved to the Lancaster area in 2014 after his almost eight and a half years of service in the U.S. Marine Corps. He went to graduate from PA College of Health Sciences with his ASN-RN then obtained his BSN from Millersville University.

Before joining our team in 2022, Trevor worked as a Psychiatric Nurse at Lancaster General Hospital, and a Registered Nurse with both Penn Medicine Lancaster General Health and at Lancaster Behavioral Health Hospital. During that time, he provided specialized care to emotionally distressed individuals in both inpatient and outpatient settings.

He is most passionate about educating himself and his clients. Trevor believes that the ability to more actively participate in one’s own mental health is paramount. The role of being an advocate and mental health ambassador is what led him into the field of nursing.

Trevor hopes to be mentor, counselor, and educator for new nurses and as a bigger advocate for mental health in the community.

One thing Trevor might tell a friend who was considering seeing a therapist or seeking other mental health services:

I would encourage them to do so. It’s normal and the stigma doesn’t make sense. When you’re hurt or sick, you go to ta doctor, and these situations are the same. The only difference is that it’s not a ‘physical problem’.”
