Fred Krellenstein, PsyD, Psychologist in Syosset
I specialize in working with both individuals and couples. My goal is to provide maximum relief from your emotional distress as quickly as possible. Towards that end, my treatment methods are aimed at helping you to live real life more happily. You can expect to be asked "What is it that you most want to change about your life?". If you are uncertain about what you want to change then sorting out that uncertainty will be our primary initial goal. I am committed to helping you achieve a deeper understanding and an effective remedy to your problem.
Whether you attend sessions along with your partner or by yourself I specialize in helping you find more fulfillment in your relationships. My aim is to help you find new ways of operating to replace old, maladaptive ones, and to empower you to handle conflicts and emotions more effectively.
Therapy has proven helpful for a variety of problems including depression, anxiety, loss, and overwhelming stress. It works best when you feel listened to and accurately understood. My goal is to actively engage you and to provide you with feedback and advice that is clear, honest, useful and effective.
