Dr Nzefeh was one of the best providers that I have talked to in a while. I’m going though post partum depression and before he ended the appointment he made sure that myself and my family were ok. I am very thankful

He is attentive and patient with me. He would answers any questions I have and would make sure that I feel comfortable taking the meds.
KPVerified patient
Martin was able to thoroughly question me, diagnose me and properly medicate me on our first session. After going through many other psychologist and many medications that weren’t working, I’m so happy that I went with knk mental health services as I now I’m somewhere with amazing costumer service and promising patient outcomes.

Martin is great! His professionalism, attitude, patience, and care is amazing! He’s currently treating my daughter and I see a major difference with her since starting her care with Martin only 2 weeks ago. I highly recommend.

Mr. Martin provides outstanding psychiatric care. His expertise and experience coupled with his genuine concern for his patients results in highly effective treatment. Wonderful service, always on time and extremely helpful.
CTVerified patient
I have really been enjoying being a patient at KNK Mental Health Service. Mary and Martin are both knowledgeable, kind, attentive providers who are helping me a lot with my treatment. It has always been easy to contact them and make appointments and they easily take care of billing to insurance and refills. Also, as a member of the LGBTQ I feel safe and taken care of receiving care from this practice! Definitely recommend this practice.
GRVerified patient
Pleased with my appointment and happy to have a provider that listens to his patients concerns. Was very communicative about connection issues during our wifi call and called my personal phone to continue the appointment. Willing to provide accomodations and pinpointing help for the issues you're experiencing. Overall a great experience so far. Highly recommend!

Mr Martin Nzefeh is a great practitioner. Very knowledgeable about mental health treatment and medication management. Flexible with appointment times and offers telehealth. He makes an excellent assessment ,and explains everything thoroughly. Overall, Mr Martin is an incredibly compassionate and capable mental health professional .
PBVerified patient
I see Martin Nzefeh and left Cervello Wellness when he did to join KNK so I could stay with him as my provider. He not only listens to all of your problems but comprehends what you’re saying and honestly cares about his patients. He’s very knowledgeable about medications, their interactions and understands the severity of mental illnesses and how troubling and disabling they can be. If you or a loved one are suffering from a mental illness/es, don’t hesitate to call KNK Mental Health and get the help you need..

Mary was very responsive to my needs. She even met with me on a Saturday morning! She was kind and a good listener. I found her to be very helpful and I highly recommend her services.
September 28, 2024Alison L.Verified patient
I never received the link to meet with Mary. I called Zocdoc to explain that I inadvertently booked two appts. on Sat., Sept. 7, 2024. 3:45 and 5:15. I got a little tangled during booking - not sure what to do. when I realized it. I hope the capability to correct a mistaken double appt., error within the site will be added Soon...
My rating (5 stars) is based on me being able to tell that Mary is a very kind, compassionate, educated woman from her picture which was further validated by reading her reviews.
September 8, 2024Cheri D.Verified patient
Prompt with appointment time, communicated clearly, I had a telemedicine visit with the provider. The only downside was that I did not receive the referral or note for work that was supposed to be emailed to me.
August 2, 2024Trinaye D.Verified patient
Great insight and excellent patient care.
AHVerified patient
This was my first ever psych related appointment so I personally had nothing to compare it to. However I must say Mary Zelio made the experience welcoming and I feel as though she really was listening to actually hear me. She expertly blended allowing me to express myself with her more clinical questions to come to a conclusion on my care. I feel confident entrusting Mary with my psych needs.
May 1, 2024Ashlee L.Verified patient
I was confused because the provider wasn't the one I thought I made an appointment with, but someone else in the practice. either way the nurse practitioner was alright. i had trouble filling out the forms for whatever reason. I would fill them out and then be told they weren't received 2 times. 3rd time worked.

ILVerified patient
I saw Mary at KNK Mental health and she was very compassionate, took time to listen to my concerns and did not just rush me to taking medications. She advised me to do more testing which I did and we later started on the right medication. I feel very comfortable and confident in what they do at KNK Mental health. Will definitely recommend this practice and especially Mary for any mental health needs.
