Eva Cozzi
Founder & Licensed Clinical Social Worker

Background:
I obtained my master’s degree in social work from the University of St Francis. I completed my masters level internship with Guardian Angel’s domestic violence program. After graduation, I continued working with this organization helping victims file for orders of protection, facilitating groups and individual therapy, answering the domestic violence hotline and doing community presentations.
My treatment approach is client centered and strength based. I like to meet the client where they are at and build off their own strengths. Using psycho education, I help clients understand their feelings and behaviors and work on new healthy coping skills. My goal is for clients to reach their highest potential not just alleviate their symptoms.
I work hard to understand, diagnose and frame what the issues really are, and work gently and intelligently with my clients to help them grow into their own abilities to change the status quo and “see” what is possible for them. This is not magic — it’s work. But hard work and a commitment by both of us to a trusting and open therapeutic relationship can produce what seems like magical outcomes. In my view, that can only happen in a place of safety and hope. I strive every day to create an atmosphere of both so that true healing and real change can actually be achieved.
Who I Treat:
Clients 3 years and older dealing with anxiety, depression, trauma, domestic violence, sexual assault (I am 65 hour cross trained in DV and SA), eating disorders, women’s issues including infertility, chronic pain, stress and lifestyle issues, parenting and family conflict.

Jennifer Vergara
Licensed Clinical Social Worker & Certified Grief Informed Professional

Background:
My passion is to help people discover more about themselves in order to identify what skills they need to function at their full potential, as well as the path to get there. I utilize a strengths perspective in my work in order to help people discover their strengths and build upon them. I believe in a client centered approach and meeting the person where they are in order to come alongside them on their journey to healing. Because the interpersonal relationship is very important in therapy, I am passionate about building a relationship based on trust, safety, and understanding. It is my hope that clients will improve their self-awareness, gain necessary skills to cope, identify necessary support systems, and utilize those outside of therapy to experience more satisfaction and peace in life. If requested, I can integrate faith based counseling into sessions.

Clients 8 years and older for Anxiety, Depression, ADHD, Trauma, Autism Spectrum Disorders, Bipolar Disorder, Learning Disabilities, Self Esteem, OCD, Grief and Self-Harm.

Genna Werner
Licensed Social Worker

Background:
With a background as a first responder, I bring a unique perspective and deep understanding of crisis intervention and trauma-informed care to my clinical work. My early career provided extensive experience supporting individuals through high-stress and emotionally complex situations, which laid the foundation for my compassionate and client-centered approach to therapy. I obtained my master’s degree in social work from Aurora University specializing in forensic social work. I completed my master’s level internships working with survivors of human trafficking and sexual exploitation and with clients in the perinatal period.
I use a strengths-based approach as well as prioritize client centered care. I am dedicated to building a safe atmosphere and strong therapeutic relationships centered on trust. I strive to meet clients where they are, offering support and gentle guidance as they grow in self-awareness and healing. I can also integrate faith-based counseling into sessions if requested.

Lisa Weingart
MSW, LSW

Background:
I earned both my Bachelor of Social Work and Master of Social Work degrees from Aurora University. During my master’s internship, I worked with adolescents and families in a Partial Hospitalization Program (PHP) and Intensive Outpatient Program (IOP) at Northwestern Medicine, supporting individuals experiencing a variety of mental health challenges.
My approach to therapy is grounded in the belief that healing happens through connection. Many people come to therapy feeling overwhelmed, misunderstood, stuck, or alone in their struggles. I believe one of the most meaningful aspects of therapy is having a space where you feel genuinely seen, heard, and validated. My goal is to create a safe, supportive environment where clients can explore their experiences openly, build self-understanding, and feel empowered to move toward meaningful change.
I take a humanistic and strengths-based approach, recognizing that each person brings unique strengths, experiences, and resilience to the therapeutic process. While symptoms and diagnoses are important to understand, I am equally interested in understanding the person behind them, their story, relationships, values, and goals.
My work is informed by attachment theory and family systems theory, which help us understand how relationships and life experiences shape the way we view ourselves and interact with others. I also integrate evidence-based approaches such as Cognitive Behavioral Therapy (CBT) and Dialectical Behavior Therapy (DBT) to help clients strengthen coping skills, improve emotional regulation, increase resilience, and navigate life’s challenges with greater confidence and flexibility.
I view therapy as a collaborative relationship built on trust, authenticity, and mutual respect. Together, we work to identify patterns, build on existing strengths, develop practical tools, and create lasting change. Whether you are facing anxiety, depression, relationship concerns, family conflict, or a significant life transition, my goal is to help you feel supported, connected, and empowered throughout your journey.
Who I Treat:
Individuals ages 12 and older experiencing anxiety, depression, emotional regulation difficulties, relationship concerns, family conflict, life transitions, self-esteem challenges, stress, and other mental health concerns.
My Treatment Approaches:
Humanistic | Person-Centered | Strengths-Based | Family Systems | Attachment-Informed | CBT | DBT | Mindfulness | Psychoeducation | Trauma-Informed | Solution-Focused
