About Us
Mental Flex LLC. Is a nurse practitioner owned, psychiatric practice designed to help strengthen your mental health. Kristen and Nichole are two NJ based Board Certified Psychiatric Nurse Practitioners who met several years ago while working as staff nurses in a busy emergency room and after witnessing first hand, much of what is lacking in mental healthcare, we decided together that we wanted to help reduce stigma and help improve access to quality mental health care. Together, we attended Monmouth University's PMHNP program, graduating in May of 2021. Since then we have worked in our respective locations building our experience to be able to provide the best care to our clients.
If you are interested in nurse driven, evidence based, up to date psychiatric care, look no further than Mental Flex LLC. Where we are committed to help you strengthen your mind.
Currently we are booking virtual appointments

'I feel like Kristen takes her time and listens to me. In the past there have been experiences with providers where the appointment felt rushed and I did not feel like that at all! I was hesitant to take medication and Kristen walks me through what the medication side effects might be and how to properly take them.'
