The TMS Collaborative — Ketamine Clinic in Exeter, NH

I feel very well cared for at TMS Collaborative. I have built a great rapport with the staff. I especially feel heard and seen by Alysha Beauchesne. Alysha listens and provides valuable feedback. She is professional and truly cares about her patients.

I was pleased with the care I got. Everyone was very professional and caring. I would highly recommend this office.

I’ve been a grateful patient of Dr. B’s for nearly 20 years for medication management of major depression, anxiety, and ADHD. He is consistently calming, attentive, open, and responsive. I have complete trust in his clinical judgment, and his entire team is both supportive and highly professional. TMS has been a true game changer for me. While it is not a cure, it is the most effective treatment I’ve experienced—allowing me to engage with life in an entirely new way, free from the persistent emptiness, overwhelm, emotional numbness, and chronic fatigue that once dominated my days. Life now feels brighter, lighter, and more spontaneously joyful, as if my senses are fully engaged without constant effort. To call this experience a miracle is not an exaggeration - I highly recommend Dr. Belliveau.

Allysha is so friendly and kind. I had a difficult episode this past week and she stayed by my side till I was doing better. She's amazing.

The staff is so very kind and supportive

Great personal experience! Very professional and engaging. Staff are very friendly and informative.

Dr. Belliveau and his team are all amazing. I’ve been a patient of Dr. B’s for nearly 20 years. They are always there when I need them, and trying out the ketamine treatments has been life changing in a good way!
