Jim Guzdziol, MBA and Phyllis O’Brien, RN | Owners
Inspiration for opening a BrightStar franchise arose from a personal experience for husband and wife Jim Guzdziol, MBA and Phyllis O’Brien, RN, owners of the Naperville office.
“We witnessed firsthand Phyllis’ mother’s need for care and the difficulties a family faces when a family member is suffering. The demands of caring for a loved one cause a great deal of stress on the primary decision maker and caregiver. It is very fulfilling to provide such a needed service. Phyllis and I view this as a tremendous opportunity to leverage our career strengths and bring a higher level of service to this community.”
After experiencing Phyl’s mother’s journey toward the end of her life, we were inspired to combine our career strengths and the BrightStar business model to bring a higher level of home care and staffing services to the surrounding communities, help families and create jobs. Jim brings over 25 years of executive-level business experience, holding C-level positions for the past ten years. Phyllis has over 25 years experience as a registered nurse. Terri Grant | Branch Director
I have been in the healthcare field for over 15 years, starting out as a CNA and an EMT. I managed a Medicare-certified and private duty Home Health Agency in Tucson, Arizona for seven years providing quality care and service to patients and their families. Before joining BrightStar I managed a Chicago-based nurse staffing agency. I am excited to be working with BrightStar where I am able to continue providing quality service to Healthcare providers and our homecare clients, which I truly enjoy and am very passionate about.Maureen Wood | Director - Business Development
My background includes lengthy tenures in business education and professional services management. As a result of my Board service for St. Paul’s House, a Health Care Center near Wrigley Field, I launched my “encore” career into serving this nation’s greatest generation. The last eight years I have focused primarily on marketing continuing care in a community setting.My most recent position as Move Management Coordinator for a new independent / assisted living and memory care community has afforded me firsthand insight into the many challenges and difficulties seniors and their families face when transitioning from their homes to senior communities – the thought of downsizing, preparing to sell your home, the actual sale and physical move — can be daunting to say the least!
I am a strong proponent of the BrightStar model because our focus is to support seniors by providing excellent care and services in the comfort of their own homes. As Dorothy from the Wizard of Oz said, “There’s no place like home.”
Marilyn Ferro, RN | Care Coordinator
With a wealth of healthcare experience, both hands-on and administrative, my passion is providing each of my clients with the highest level of care possible. As an electro-diagnostic technician at the local community hospital and on weekends in a physician’s private practice performing specialized neurologic testing, I gained a solid neurological knowledge base and learned the value of patient education and compassionate care. Later, while managing a physician’s private specialty practice devoted to children with neurologic challenges, I completed my nursing degree. As a Care Coordinator my role is to assess each patient’s needs and provide recommendations, linkages to services and oversight of medical services to ensure an integrated approach to optimal care. Each client is treated as though they were my mom or dad.Jen Winarski, RN | Care Coordinator
I was a Junior Volunteer at age 13, became passionate about helping others and spent the next 25 years in various areas of healthcare, including hospitals, physician offices, clinics, treatment centers, schools and administrative offices. Being a strong believer in faith and family, I am an active member of the Council of Catholic Women in my parish.I love being a registered nurse because of the positive impact I can make in people’s lives, and truly feel I have been called to be an advocate for patients and their families. This means being committed to listening to the needs of my clients and their families and working proactively with other healthcare disciplines to problem solve and deliver the best solution. You will find that I’m a down-to-earth healthcare provider that sees each client as a person and gets to know each one and their family members on an individual level.
