Hypnotherapy Service Testimonials from Satisfied Clients


I’m very pleased with my decision to meet with Dr. Terzaghi who I think is one of the top hypnotherapist in New York and I look forward to our weekly sessions. I was in a very dark place in my life when I decided to start hypnosis therapy. At first, when Dr. Terzaghi told me about hypnotherapy I was a bit apprehensive but I was also willing to try something different as my previous visits to other Doctors did not prove successful. Dr. Terzaghi explained how the process works

and answered all my questions which put me at ease. Dr. Terzaghi listens to my fears and stress factors. We focus on the subconscious and how to re-program the way I react to those stress triggers. After the first hypnotherapy session was completed I noticed the immediate results. Not only was I more relaxed and able to breath in an easier manner, but I felt
empowered to address my fears. My stress levels have definitely decreased since I started seeing Dr. Terzaghi. I enjoy every visit and feel that I am making good progress towards my end goal. I recommend Dr. Terzaghi if you experiencing stress levels in your life and you are seeking professional help a hypnotherapy expert.

When I first saw Dr. Terzaghi who is a well know hypnotherapist expert in Manhattan, New York, I was suffering from IBS associated with anxiety on a daily basis on my commute to and from work. It got to the point where I was unable to go to work for a couple of days and had to work from home. I was able to get an appointment right away. On the first visit we discussed what was going on and Dr. Terzaghi did the first hypnosis with some suggestions that I will be comfortable and relaxed on my commute. Those suggestions worked from the start. Each week Dr. Terzaghi listened to how the previous week went and tweaked the hypnosis therapy process as needed. I am very pleased with the results and would highly recommend Dr. Terzaghi .

Dr. Terzaghi has had a profound and positive impact on all aspects of my life. She recognizes the uniqueness of an individual’s past experiences, and with her thorough approach, was able to help me understand and analyze a series of key events which have shaped my own way of seeing the world. It is through her guided analysis of my own patterns of thinking that I have been able to decrease
my anxiety and understand myself to a higher degree. Importantly, I feel Dr. Terzaghi’s ability to be both compassionate and “tough” throughout our time together has illustrated her true skill as a psychologist. I would recommend her without any reservations.

“I have made significant positive changes in my life due to Dr Terzaghi’s techniques that explore deeper levels of consciouness. I have been to other therapists before who use more superfical approaches like CBT but the treatments did not help me achieve significant nor long-lasting change. She is highly knowledgeable and a compassionate therapist. She helped me and she can help other people who seek real change in their lives. ”

“I have seen Dr. Mari Terzaghi’s, who is one of the top hypnotherapist here in NY; repeatedly over the last several years to deal with several issues and I have found her from our first meeting to be extremely caring, insightful, knowledgeable, and genuinely interested in my well-being. In the years that I’ve seen her, I’ve dealt with a variety of issues that only a Hypnosis therapy expert can address– the death of a spouse and its accompanying depression, work issues, health issues, sleep issues, and anxiety over flying. In every case she has been tremendously helpful. From traditional therapy to hypnotherapy, she has been instrumental in helping me achieve both personal and professional change and growth. ”
