Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Exceptional Care and Expertise from Dr. Thad R. De
Dr. Thad R. Denehy has been a trusted and exceptional physician for over 30 years, providing outstanding care to my loved one. From the moment we met him, it was clear that he is a rare combination of an extraordinary surgeon and a compassionate, patient-centered doctor. There is no question in my mind that he is among the best.What sets Dr. Denehy apart is not just his surgical skill but his approach to patient care. He combines an unmatched level of precision with genuine empathy, and it’s evident in everything he does. Dr. Denehy has an incredible ability to make complex information clear, ensuring his patients fully understand their treatment options. When my loved one faced a difficult situation, Dr. Denehy didn’t just address the medical aspects—he communicated openly, thoughtfully, and with great care. He personally called to explain everything, taking the time to listen to our concerns and answer any questions. His direct yet compassionate approach was incredibly reassuring,

traumatic experience
Terrible. Had surgery with him. He did not tell me he was leaving town the next day. I had severe pain. His medical staff was hard to reach. He was totally unreachable. On a later follow-up visit, he told me why I had the pain — but he hadn’t prepared me.

Telehealth
My consultation didn't go well. I was asked some invasive questions even though I was asexual. I didn't appreciate this at all. I was referred to him by another physician but I couldn't proceed with the surgery because of the unnecessary examination. I already told the referring physician about my concerns but it seemed like they didn't communicate my requests amongst themselves.

The WORST. No one knows in this office know how to talk to people. The medical staff never answer the phone, and they don’t call back if you leave a message. Denehy and his nurses don’t explain anything. This office feels like a body factory, because they treat patients like body parts. Deneny once pointed to my breasts and said, “does your regular gyno check those for you.” He’s greatly exaggerated the amount of time he’s spent with me in his notes. He’s sat there signing paperwork while talking to me about my health. He’s allowed staff members to come in and talk about other patients during exams. He’s told me I should remove body parts, not because there was something wrong with them, but “because you’re not using them anymore.” Stay. Away.

Awful
No one in this office has any idea how to speak to humans. They treat patients as body parts with wallets. Good luck getting a call back if you need to speak to someone - it can take WEEKS for someone to return your call.

Excellent skills!!
Dr Denehy was the only surgeon who could handle my complicated surgery. No other doctor would operate on me as there was extensive scar tissue and adhesions from 5 prior gynecological surgeries. Dr. Denehy was confident and not detoured by the level of difficulty of removing almost 40 fibroid tumors and a full hysterectomy, even with the challenge of the severe scar tissue. The surgery was a complete success and I will be forever grateful for his immense surgical skills. He is truly a gifted surgeon!

I can’t say enough about Dr Deheny. He has performed two surgeries on me and both were successful. He gave me my quality of life back. I wouldn’t hesitate to see him or recommend anyone to him.

Outstanding Doctor
Dr. Denehy is an outstanding doctor. I have been Dr. Denehy’s patient for the past few years. His surgical skills are superior as I can attest to having had two successful complicated surgeries. In each instance he was patient and compassionate and took the time to answer my questions and concerns. He discussed with me my surgical options and why he had chosen the one that best suited my situation. I would recommend Dr. Denehy to anyone needing his expertise and skill. I am truly blessed to have had Dr. Denehy as my surgeon.

Bad Experience
Horrible, I initially had my first visit with Dr. Thad Denehy which went well. He referred me to Dr. Eric Liberman due to him being busy and it will take 3months. Well, it's now been 4 months and no surgery date. A biopsy was conducted and a month later was notified that he didn't take enough and it had to be done again which the procedure is painful. You can never get in contact with him or the staff. At this point I'm seeking another specialist. Time wasted since October.

Extremely rude office personnel were loud, condescending and insulting. I first questioned the photo consent then declined it. With the little power they have, the first desk clerk added more time to my already long wait by calling 3 people who arrived after me to be seen first. I did not feel welcomed there from the time I arrived. The doctor, Thad Denehy, MD, was no better than his office staff. He was loud, extremely impatient and an overall egotistical bully. This was not the doctor I had read about with all the outstanding credentials. My assumptions regarding Dr. Denehy's disposition and decorum were all wrong. The doctor I saw was short tempered, crass and behaved nothing like a physician should. I knew within 2 minutes of encountering Dr. Denehy that he was not for me. I skipped the exam and practically ran out of there.

Dr. Denehy is amazing. I felt like his evaluation of my health was very decisive and comprehensive. My surgery went perfectly, apart from a random, out-of-network surgeon joining in, unbeknownst to me - that was expensive! Dr. Denehy’s office staff is abysmal, though. They don’t return phone calls, don’t fill out paperwork in a timely manner, and their attitude is indifferent at best. I was happy to have superior healthcare from an excellent surgeon, but the experience was frustrating and miserable with his office staff.

My experience with Dr. Denehy was a 5-star!!!! Dr. Denehy is an excellent, top-notch, straight forward doctor. I had a very large fibroid and was worried how it would impact my ability to have children, and Dr. Denehy was very direct in what he plans to do with his surgery and advised me of his surgical options. While I was waiting to be taken into surgery, Dr. Denehy saw that I was visibly nervous and came to my bedside to chat and while also having one of his nurses give me something to ease my tension. This is just a depiction of his ability to not only be a great doctor, but to also show that he is always watching his patients and what is going on. I really appreciated this because it is a more personable experience with the doctor and shows his awareness and level of care for his patients. I am so grateful to Dr. Denehy for making this experience as seamless as possible and for the amazing outcome! I would HIGHLY recommend Dr. Denehy to anyone especially with more complex issues!

My wife has been a patient of Dr Denehy's Livingston office for over 8 years. Ever since Dr. Taylor left, she has noticed a remarkable decline in the way her medical care has been handled by his office staff and their complete ineptitude and lack of compassion. One staff member has consistently called in the wrong prescriptions, notes the incorrect appointment times, and in-person, has the attitude of someone who is being inconvenienced by them having to actually do their job. When issues arise where biopsies and scans are needed, the disconnect between doctor and patient becomes glaringly obvious. When a doctor’s practice operates a revolving door of patients, office staff have a tremendous amount of responsibility. However, they also have a tremendous amount of power to screen patient's calls, keep them from speaking with doctor's directly, and all-around fail, with no repercussions, in getting their patient's the prompt medical attention they may need. Use at your own risk.

It's hard to leave a review for a doctor online, as we want our patient confidentiality to be maintained. Let me just say that after 10+ years of dealing with a health issue that every other doctor shrugged at, I finally found Dr. Denehy. He listens, he's a straight shooter, and most importantly he's a master in his field. I've had two procedures by him and have never felt so safe and taken care of. I've met strangers who raved about him in passing, and nurses who told me he's the one they call when things go haywire in the hospital. There are not enough words to thank Dr. Denehy for the pain free life he has given me!!! If you're looking for a doctor, don't think twice, we need more doctors like him!!!
