Schedule A Therapy Session Today

Sometimes, life really can be difficult for any of us. Take the first step to relieve, solve, and enrich your life.  You deserve to have a support system like our Long Island, New York psychotherapy services.

We understand that taking the first step toward mental wellness and finding the right therapist can be daunting, but rest assured, you're not alone. At Nassau Guidance & Counseling, we're committed to matching you with a psychotherapist who will guide you through your journey with compassion and expertise.

Each therapy session is a safe, nonjudgmental space where you can freely express your thoughts, feelings, and experiences. Our main priority is to help you live the life you really want. This may mean:

  • Helping you to change negative thought patterns which may trigger anxiety and/or depression or create obstacles to moving forward in a relationship or a job.
  • Having a distorted perception of who you really are and what you truly are capable of accomplishing. 
  • Growing and expanding beyond your limited belief system.
  • Working through guilt and anger instead of staying stuck there.
  • Empowering you to move forward with what you want, as opposed to being stuck in fear. 
  • Wanting to help you with conflicts within your relationship and help you remember the reason you got together in the first place.
  • Assisting you with working through emotional pain, trauma, and grief so that you may live the life you deserve to live, even having gone through these experiences.

Remember, seeking help is a sign of strength. By reaching out, you're taking a courageous step towards a healthier, happier life. We look forward to accompanying you on your journey.
