"After over a decade with Dr. Olga Segal, I'm still amazed at her expertise and kindness. Now, doing TMS therapy under her guidance, I'm experiencing significant improvements in my memory. This is truly fantastic! Also doing therapy with Paul and Med Management with Lisa. Very happy with the team."

"In a world often shrouded in clouds, Dr. Olga Segal and her assistant Simon are rays of sunlight. Their attentive care during my two rounds of TMS therapy has instilled in me a renewed sense of hope and wellbeing. Dr. Segal's comforting presence, coupled with her impressive expertise, feels like a steady hand guiding you towards brighter days. After my TMS experience with them, I feel lighter, stronger, and more hopeful. To anyone feeling lost in the storm, I can't recommend Dr. Segal enough. Her compassionate approach truly illuminates the path to better mental health."

"Words fall short in expressing my gratitude towards Dr. Olga Segal and Simon. As I journey through my third round of TMS therapy under their care, I find myself rekindling the joy of feeling truly alive. The brain fog that once clouded my daily life has lifted, replaced by a newfound clarity that's refreshing. TMS therapy, under their expert guidance, has proven to be a transformative force in my life. A humble 'thank you' seems barely enough for the immense change they've ushered into my world."

Dr. Segal's staff is incredibly knowledgeable and had my best interests at heart. I enjoyed each appointment with Dr. Segal because of her attention to detail which led to a treatment plan that is effective for me."

"Before I started TMS therapy I suffered from deep depression and anxiety. As the sessions progressed, my mood improved, and my mind started to feel clearer. The transformation I've seen in myself is nothing short of a miracle, and I am super thankful of Dr. Segal's staff who were extremely professional, yet caring and sensitive to my needs. Highly recommend them if you are looking for TMS therapy. "

"I feel grateful knowledgeable, caring, and nonjudgmental. Olga and Kevin are great! Thank you, Thank you! You guys changed my life! I was seeing by Olga and Kevin I can not even compare how much my life has changed since then. Very clear communication. Went above and beyond to see my needs were met."

"Scam artists! I don't use that term lightly. I was a patient very briefly, found their service incredibly lacking (my NP didn't even remember what he had previously prescribed me and tried to recommend the same thing that made me sick literally 2 months after taking me off it and my therapist just repeated dumb platitudes and did the "how does that make you feel" treatment) so stopped going. Over a year later, they started taking money out of my bank account at random, overdrafting me. They took $750 in what I am confident are fraudulent charges, as I stopped seeing them over a year ago and never made any other appointments! I asked them for documentation proving these appointments ever happened and they ignored my email, instead just replying to confirm their total and letting me know they would be taking it. I asked for an itemized bill and it straight up was not provided. I'll be reporting them to the Dept of Health. Do NOT go here. "

"Stopped going here after like 3 months because the quality of care was just not that there. The entire reason I called this office was to get a female dr but the actual Dr Segal doesn't seem to ever be available. I always dealt with Knack, who prescribed me a med that made me sick (not his fault), then another that didn't work (also not his fault) but then immediately tried to enthusiastically prescribe me the first one again-- like he completely forgot it me made me sick or didn't bother to review his own short history of notes before our chat. Completely impersonal care. It feels like everyone in this office is just reading off a list of platitudes and scripts and is ingenuine about helping people. Not only that, but they keep (OVER 6 MONTHS LATER) taking random amounts of money from my debit account. They overdrafted me while I was in the middle of getting a home loan approved! I'm not even a patient anymore-- what the hell are you charging me $300+ for?!? On top of all that, they won't ...

" I’ve been trying to be seen by Dr. Segal’s office for four months now, to no avail. The registration process has been disorganized and confusing beyond words. I was finally able to get an appointment at 2:30 today. I spoke with the receptionist to confirm, and received a text informing me it was time to check in at 1:40. After sitting on zoom for 30 minutes, and calling the office every 5 to make sure I have the right link, etc. the receptionist called to let me know that my appointment had been at 2:30 eastern standard time. I explain that she hadn’t mentioned that when I made the appointment, and I emailed a screenshot of the text. At this point, she became exceptionally rude and condescending saying that I couldn’t count on the text message from the clinic to contain accurate information, and that I should have been checking my email. The next available appointment is in three weeks. I’m not able to get out of bed. I’m not eating. I didn’t think I needed to triple check and triangulate ...
information given to me verbally, via text, AND EMAIL. And this exchange has left me with zero confidence in the quality of care I can expect from the office. Looking at reviews online, I see that I’m not the only person left baffled by the hostility and disorganization by Dr. Segals team. "
