"I saw Dr. Glassmann for some time, and I found him to be friendly and easy to talk to, but always professional and focused on my issues.  I felt very comfortable with him and he regularly provided insightful guidance and suggestions that were most helpful.  He is quite knowledgeable in his field (and a wide range of subjects too!) and a most able counselor/therapist.  I have no hesitation recommending him highly."

My husband and I agree that couple's counseling with Marvin Glassmann has enriched our relationship tremendously.  We found his help in learning better communication skills and solving our issues extremely helpful,  He made us comfortable with his easy and informal approach, as well as his humor.   He helped us to put focus on the strengths we each possessed, as well as those we already had as a couple.  This positive approach to looking at our relationship was incredibly helpful.  Not only did it lower the defenses we entered therapy with, but it enabled us to be more open to the individual changes we could each make to create a better relationship.  We are going on 33 years of marriage at this time and we are sure that the insights and tools that we gained from our work with Marvin has enriched our love and understanding for one another.  We highly recommend him for any couple who needs help on their marital journey.

I have known Dr. Marvin Glassmann for more than two decades, both professionally and personally. I can attest to his integrity as a psychologist and marriage and family therapist. I have known him to be committed to providing the highest quality of care to his clients with the utmost respect, kindness and knowledge-based skills. As President of the Long Island Association of Marriage and Family Therapy he was a great leader and committed to the organization, offering warmth and great support to the membership. He was astute about Association business, especially guiding therapists through the certification process, and was an excellent presenter of his wide-ranging clinical material. He has been recognized for his many accomplishments by several professional organizations, all well-deserved. On a personal note, he is generous, warm, gentle, kind and open-hearted.
