Guiding Your Mental Wellness

Step-By-Step Health, LLC is a psychiatric mental health practice serving children, adolescents, and adults throughout Port St. Lucie and across Florida. We provide medication management, brief therapy, and compassionate, steady support - offering both in-person and secure telehealth visits - so you can move toward greater stability, resilience, and everyday well-being.

A Practice Built For Today

After caring for patients as a nurse since 2013 and witnessing how COVID-19 deeply intensified anxiety, depression, and stress for individuals and families, we created Step-By-Step Health in 2023. We are committed to meeting your mental health needs through shorter wait times, secure telehealth visits, clear communication, and care that fits real, busy lives.

How We Support Your Journey

We start with a careful evaluation, then create a plan together that may include psychiatric medication management, brief therapy, and practical education tailored to your needs. Every step is discussed openly so you understand options, benefits, and risks, insurance and scheduling details, and what to expect. Our goal is to help you feel safer, more stable, and more confident in daily life.

Inviting You To Take A Step

Every person's story is different, and progress happens one step at a time. We offer a calm, private setting, flexible telehealth appointments, and guidance that respects your pace. Our team can help you review insurance options and create a personalized care plan. Explore our FAQs, review services, or request an appointment when you feel ready to begin.

I had a great experience with Liziana! She suggested some new changes and I think the may have gotten to the bottom of some problems other psychiatrists were missing.
