Her journey toward becoming a health advocate is deeply personal—after achieving a 200-pound weight loss herself, Jessica developed a unique perspective on the physical, emotional, and behavioral aspects of wellness. This experience drives her compassionate and realistic approach to patient care, empowering others to take control of their health through education, balance, and individualized care plans.

Marta Shevchenk
A board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP) with a strong foundation in both inpatient and outpatient mental health care. I work with clients who are navigating challenges like anxiety, depression, trauma and other mental health issues. As an immigrant myself, I understand how complex it can be to balance cultures, identities, and the pressures of adapting to a new environment. My background as a nurse and nurse practitioner has given me the privilege of working with people from a wide range of cultural and ethnic backgrounds—and that has shaped my practice in a deep and meaningful way. I’m bilingual, and speak fluent Polish and I also understand and speak some Spanish and Russian. I believe language and cultural awareness are key parts of mental healthcare. My approach is supportive, collaborative, and focused on helping my clients feel seen, heard, and empowered to make meaningful change

Jessica Clarke
I have been in health care for the last 12 years. When I am not working I am raising children. I enjoy giving back to my community by being of service at church and the recovery community. Helping people is what I enjoy doing. My favorite part of being part of Revitalized Wellness is how much we all care about the people we serve. We are really changing people's lives, I am also learning to change my life.
Michelle Ross
My hobbies are golfing, fishing, kayaking, going on hikes. I love spending time with my grandkids and family. Three years ago, I changed my lifestyle by eating healthier and spending plenty of time outside.
