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.

My child has been a patient for about 2 years. She has autism/epilepsy. He was able to do what no one was able to do. We have gotten multiple EEG’s, where before it was an impossibility. He had genetic blood work done. He discovered things. He gave us answers in black and white data where no one else was able to. He is super responsive to emails and phone calls and truly cares. He has a real passion for what he does and is very proactive, yet careful. He also takes a lot of time with his patients. I was skeptical as we have been to several doctors and specialists. We put our faith in him and it has paid off. He is highly recommended by our family.

Dr. Zinnanti is a life saver! Besides being very knowledgeable about my injury, he was so caring on my very first visit where I broke down and actually cried in the exam room. I was in so much pain, very upset and agitated. He was so comforting and reassuring during my exam. Besides being prompt, professional, polite, courteous, with a wonderful bedside manner, he told me he would be able to help me and get me back to being a functioning person again and in a much greater capacity . Dr. Zinnanti is truly a caring person. You can see it when he communicates with his staff or meeting with a patient. He checks in, calls and makes sure he has a one to one conversation with you before and after treatments. He is thorough when explaining the recommended therapy and has great patience understanding he is dealing with a person with a head injury. If I could give Dr. Zinnanti 10 stars on this review I would. He truly gave me my life back and my career. Ron Evans, patient.

Dr. Zinnanti is always available when we have questions about our son who suffers from seizures. He listens, he care about my son. He accommodates us all the time. He is here to help. He is kind, he follows up with his clients. Knowledgeable with kids that have different needs. We have a beautiful connection with Dr. Z we can email him and he replys, who does that? He has made a big difference on my sons care I thank him all the time, he is the reason why our son is thriving. I recommend him 100% and his staff is wonderful. Lovely always smiles.

Horrible experience. Accused family member of yelling at his staff when in fact it was some other client and never apologized. Threatened to report to CPS if family did not follow his recommendations. Later learned that this has happened to some of his other patients. Took numerous written requests to obtain copies of medical records. Horrible attitudes and customer/patient service. Would never ever recommend this physician.

Dr. Zinnanti helped me get my life back after a seemingly minor concussion while surfing left me in agony for months with post-concussion syndrome. Other doctors insisted I wait and be patient and were cold, but Dr. Zinnanti worked with my schedule and insurance to make sure I got the care I needed. The hyperbaric chamber gave me relief and hope, which became a great cycle that along with a tailored treatment plan got me better than I was before the accident! His staff are AWESOME, best Dr ever!

Told me my sons “swearing” tic with Tourette’s was his choice and his bad choices. That he has control over it. Apparently he’s never heard of coprolalia. Due to this he basically dumped my teen and told us to see psychiatrist. Would not recommend this dr if your child has Tourette’s.

I see him for adult adhd and it's the first time I'v taken a prescription drug so I've been trying different prescriptions and doses. Each office visit is pleasant and his staff are always really nice. He's very attentive and concerned for my well being which isn't something you always get with doctors. Sometimes you get to meet his wife, she's also really nice.

As a professional that works closely with Dr. Zinnanti, I can unequivocally state that you will be in good hands. Not only have I referred patients to Dr. Z, I have referred my family members. In fact, he is the only person that has been able to reduce my wife headaches. This is someone who's capability matches his bedside manner, and both are exemplary.

I was very pleased with Dr Zinnanti at every level. I saw him because of a sports related traumatic brain injury and I was looking at Hyperbaric Oxygen Treatment (HBOT) to assist in healing. Not only was he extremely knowledgeable and professional in this area, he was also extremely compassionate and genuinely invested in my healing process. If 6 stars were available in this review that's what I would give him.

When I started visits I was having mood swings and terrible headaches once or twice a week, mood swings were terrible! Dr Zinnanti diagnosed my as bi-polar, I was ADD or ADHD as a child, and started treatment/medication asap; my mood swings are 100% better The headaches; post traumatic headache disorder from a subdural hematoma as a young man. The hyperbaric chamber has eliminated the headaches completely; I assumed headaches would be part of my life. Dr Zinnanti is very Patient.
