Community-Based: Prevention, Advocacy & Outreach Graduate Course
I have experience working at Lurie's Children's Hospital Inpatient Psychiatric Unit and Partial Hospitalization Program. I have worked at multiple private practice's in the Chicagoland area before opening MSC. After opening the practice I developed a successful Leadership Workshop focused on confidence, stress, and leadership for middle school girls. During the pandemic we had to cancel all of our in person workshops. I began posting mental health content on social media to help my community. Passionate about prevention work, I am honored to have a following of over half a million that I share mental health content with! I have been in mainstream media such as The New York Times, Good Morning America, Counseling Today and gave a Tedx Talk about Investing in Your Mental Health. This past year, I was asked to participate in a partnership with Harvard University regarding content creation and mental health prevention work. Lastly, I provide mental health trainings and talks to high school teams, colleges, classes, and more. I have consulted on therapeutic cases and corporate wellness programs.
My Focus: ADHD, Anxiety, Oppositional Behaviors, Parent Coaching & Teen Issues

Juris Doctor
I have a passion for helping adolescents and adults overcome obstacles, develop mental strength, and build meaningful relationships. I have a wide range of experience in agency, school and private practice settings. I am committed to listening to my clients in a compassionate non-judgemental manner so that together we can process your experiences, build skills and generate solutions. Our connection is the most important factor in your success and my first priority. By understanding your established patterns of thinking, feeling and behaving we can identify what is keeping you stuck and discover new possibilities for your life. I am deeply connected to the challenges that accompany parenting and bring my clinical and personal experience into therapy. Having three children (elementary school, middle school and high-school-aged), allows me to better understand your parenting struggles. I have worked extensively with children diagnosed with ADHD, Anxiety, OCD, Depression and Autism, and believe that working with parents is an important part of the therapeutic process.
My Focus: Anxiety, Life Transitions, Women's Issues & Parent Coaching

Carly Brown, LCPC
B.A. in Psychology, Minor in Human Relations
M.A. Clinical Mental Health Counseling
I am devoted to helping adolescents, young adults, and adults with any hardships you’re having. I have diverse clinical experience in suicide prevention and have worked at multiple crisis hotlines. Clinically, at North Park Universities Counseling Services Center I had the opportunity to work with students from all different backgrounds through individual therapy. Students presented with a wide range of issues such as: anxiety, depression, trauma, transitional issues, self-harm, disordered eating, academic problems, identity, and self-esteem issues. It's my belief that the relationship with the client is the most important element to a successful and beneficial therapy experience. I vow to listen to every client in a non-judgmental manner and create a safe space to openly discuss your thoughts and emotions. Together we can strengthen your understanding of self, learn helpful coping strategies, and instill healing. I utilize several theories to best meet the goals of my clients, including a strong focus on Person-Centered, CBT, and DBT approaches. My goal is to build a strong therapeutic relationship with a foundation of trust. I believe in guiding my clients at a pace that you’re comfortable with to get you where you want to be.
My Focus: Anxiety, Depression, Life Transitions & Stress

Cassondra Lester
​B.A. in Psychology
M.S. in Clinical Mental Health Counseling, Current Student
I am currently pursuing a Master’s degree in Clinical Mental Health Counseling at Loyola University Chicago. The most important thing to me is to create an open, safe space where clients feel comfortable to be their authentic selves. In my past professional experiences, I have worked in schools as an intervention specialist, substitute teacher, and as an after-care teacher. I am devoted to helping individuals of all ages through their hardships or just be the person they can count on to be kind to them. Through my work experience, school experience, and personal experience with therapy, I have found that the three most important things to the therapeutic relationship are trust, comfortability, and feeling listened to. I strive to create an environment in which my clients feel safe, comfortable, and heard. My vow to you is that I will listen with an open heart and mind.
My Focus: Anxiety, Self-Esteem, Emotional Regulation & Executive Functioning

Bailey Sineni
B.A Psychology
M.A. Human Resources and Industrial Relations
Master of Social Work, Mental Health, Integrated Health, & Substance Abuse Candidate
I am currently pursuing a Master of Social Work at the University of Michigan–Ann Arbor, specializing in mental health, integrated health, women’s health, and trauma. My approach to psychotherapy is rooted in the belief that healing extends beyond symptom management—it involves cultivating deep self-awareness, resilience, and a sense of agency in one’s own life. I strive to create a therapeutic space where clients feel seen, heard, and supported as they navigate challenges and work toward meaningful change. I integrate traditional therapeutic modalities with a holistic lens, incorporating evidence-based practices alongside somatic and mindfulness-based techniques. As a Certified Trauma-Informed Breathwork and Meditation Facilitator, I utilize breathwork as a complementary tool to deepen self-regulation, emotional processing, and nervous system balance within the therapeutic journey. My goal is to create a compassionate, individualized approach that honors both the mind and body. At the core of my work is a commitment to fostering authentic relationships and creating a safe, nonjudgmental space where clients feel empowered to explore, heal, and grow. I look forward to walking alongside you on your journey toward healing, balance, and self-discovery.
My Focus: Anxiety, Depression, Relationships, Trauma, Women’s Integrated Health
