MEET OUR PROVIDERS
Sidonie Justynski, FNP-BC, PMHNP-BC
Sidonie Justynski is a dual board-certified Family Nurse Practitioner and Psychiatric Mental Health Nurse Practitioner specialized in integrative psychiatry, trauma informed care, and whole-person healing.
Her approach bridges evidence-based medicine with emotional intelligence, spiritual grounding, and a deep respect for the human journey. Sidonie provides tele-psychiatry services, weight-management support, and psychological wellness frameworks that empower individuals to reclaim identity, stability, and inner peace.
With more than 16 years of clinical experience—and a lifetime of lived experience—her philosophy is rooted in one truth:
Healing is not just the absence of symptoms.
Healing is the rebuilding of the self which includes the mind, body, and soul.
You are not here by accident.
You are here because something in you is ready for more.
More clarity.
More peace.
More alignment.
More of the person God always intended you to be.
As a dual-certified Family and Psychiatric Mental Health Nurse Practitioner, I merge evidence-based medicine with emotional intelligence, spiritual grounding, and therapeutic storytelling. My work is rooted in personal resilience—surviving an abusive marriage, navigating 14 surgeries in 2022, rebuilding my life, finding love, and enduring the heartbreak of losing my father in March 2025.
From this journey, a phoenix was born.
And now, I help others rise too.

Shqipe Ademi, PA-C
I am passionate and experienced in treating clients with mood and thought disorders (depression, anxiety, bipolar, schizophrenia), ADHD, PTSD, suicidal ideation and addiction. I will work collaboratively with you to identify your goals and recognize your strengths in a safe, nonjudgmental and welcoming environment. I am also extremely passionate about working with the LGBTQ+ community, and believe cultural identity is an important piece of the treatment process. I value individual uniqueness, and will work with you to discover your values and grow and process in a way that promotes dignity, respect and compassion.
I am board certified as a Physician Assistant with a specialty in psychiatry. I believe there should be no stigma when it comes to mental health, and that vulnerability is a great strength. While I have a long career in the medical field (15+ years), focusing on psychiatry and mental health has always been a passion of mine, and I hope to help you discover the importance of prioritizing mental health care for yourself. I am committed to work closely with my patients to find a collaborative solution that combines prescription of individualized medications and providing supportive resources. I see my clients as the experts of their lives, and building a therapeutic alliance is how we will work together towards achieving mental wellness.

our Approach
We use an integrative healing framework (Clinical + Spiritual Fusion). Our practice is built upon four pillars—each grounded in science, spirituality, and the psychology of transformation:
trauma awareness
Understanding the nervous system, emotional triggers, attachment wounds, and the hidden narratives that shape behavior.
psychological reset
Disrupting maladaptive patterns, restoring cognitive clarity, and rewiring the mind for resilience.
Together, these pillars supports you as you move from survival to stability… and eventually, to transformation.
Ready to begin your journey?
Your healing, clarity, and transformation starts here.
mindset rebuilding
A structured process of becoming—one decision, one boundary, one new belief at a time.
spiritual grounding
Faith, purpose, identity, gratitude, and the unseen forces that strengthen the soul.
HEALING THE MIND, EMPOWERING THE SOUL
01
wake up
OUR MANTRA
Wake up to hope.
Wake up to possibility.
Wake up to the realization that your past does not determine your future.
Healing begins with awareness.
Awareness of your patterns.
Awareness of your strengths.
Awareness that change is possible.
02
make up
Make up your mind that you deserve healing.
Choose growth over fear.
Choose courage over comfort.
Choose to believe that setbacks do not define you.
Every transformation begins with a decision.
03
dress up
Dress up for yourself.
Not for validation.
Not for perfection.
Not for anyone else's expectations.
Dress up because identity matters.
Self-respect matters.
Confidence matters.
Sometimes putting yourself together is an act of healing.
04
show up
Show up for therapy.
Show up for your medication.
Show up for your workout.
Show up for your nutrition.
Show up for your family.
Show up for your dreams.
Most importantly...
Show up for yourself.
Healing is rarely one dramatic event.
Healing happens through ordinary acts of consistency.
RISE UP.
Rise above the pain.
Rise above the fear.
Rise above old beliefs that no longer serve you.
Rise into purpose.
Rise into confidence.
Rise into health.
Rise into the person you were always meant to become.
At Serenity Healthcare Services, we call this becoming the Phoenix.
THE SERENITY PHILOSOPHY
Our mantra is more than a motivational phrase.
It is a philosophy of healing.
A reminder that recovery is not about perfection.
It is about progress.
It is about making one good decision after another.
Whether you are healing from anxiety, depression, trauma, grief, ADHD, burnout, chronic stress, emotional eating, medication-related weight gain, obesity, chronic illness, or major life transitions, the journey begins the same way.
Wake up.
Make up.
Dress up.
Show up.
And little by little...
Rise up.
