Going to any medical facility is always nerve wracking. But Dr. Zak walks in, warmly greets you, and you know everything will be ok. At least that was my experience.

Hour wait but all was good thank you
If you want to see a Dr whose exam is only for 5 minutes with a grumpy face than you are at the right address, he even did not exam me, just asked me what brings me in, after I explain my pain he said to me you should use Meloxicam, thats it, the exam was over. He even did not say hello when he came to the room, he did not smile once, his attitude was like someone is keeping him in this office with torture, he looks like he hates his job. I never recommend this doctor to anyone.
It was good
Good Dr!
Great
Dr. Collins and her staff were very professional, personable, and knowledgeable. Dr. Collins handled my problem compassionately, and efficiently. I would recommend her highly.
I loved Dr Collins ability to listen abd address the problem allowing me to express my concerns I felt very much at ease and trusted her with my course of treatment
Dr Eingorn is very knowledgeable and skilled at pain relief!
Fantastic & caring doctor
Always my goto orthopedic physician with competent efficient care. Got me in for immediate evaluation and treatment for an injury. Office is clean and staff are exceptional in experience and care. I can't be more satisfied with his concern, and care given to date!
Great experience with my knee troubles
Going to any medical facility is always nerve wracking. But Dr. Zak walks in, warmly greets you, and you know everything will be ok. At least that was my experience. I've fractured my foot twice and both times I felt he truly cared and took good care of my fractured foot. I hope I never have to see him again, but if I do, I know I'll be fine. Thank you Dr. Zak!!
I went in with a plantar’s wart that was causing a lot of pain in my foot and ankle when I walk. I hoped that there would be something more than lotion to continue put on it. Although, I was quickly told that there “isn’t much I can do” and that I will continue to be pained with these warts for the rest of my life, despite this being my only ever instance of a wart especially on my foot. I know the cause and chances of a possible return but I left with the impression that the wart won’t go away or continually come back and that lotion, a stone for removing dead skin, and prayers are the only solution to this wart.
Laid back , Communicates well with Patience !! 10. OUT OF 10 Listens , lets you ask questions !!
Very professional
Very professional and helped with the problem. My husband has used the De for over 30 years
I had a great appt. With Dr Eingorn on 1/23 after my total L knee was done on 1/2/2025. He was pleased how far I came with therapy. He added 4.more weeks of therapy.
No wait time at all!
Visit went well with some answers. Thanks Doc.
Excellent
So kind and patient I'm always scared when going to my doctor appointments but I feel welcome and calm when I finally arrive in the room and the staff is so nice Dr Zak is an old school gentleman I admire the handshake at the end of my appointment it makes me smile and forget my worry Thank you Dr Zak for standing by the Oath to help people in need of your service and talent
Dr. Collins took the time to explain all that was going on with my fracture. She also said she was available for any additional questions or concerns. A very pleasant visit all around!
Excellent
Dr. Eingorn is very professional and "factual". He looks at the information and makes quick decisions based upon what he sees. He is not a "warm and fuzzy" person but you don't need him to be if he gets the job done correctly!
He answered my questions and gave me encouragement.
Very personable
Excellent experience.
Dr. Eingorn was supportive and provided an explanation to resolve my pain issues. I was very satisfied with the diagnosis and appreciate his professionalism and care he provided during my appointment.
This was a necessary followup doctor visit after a trip to the ER. The staff worked with me to schedule an appointment the same day. Dr. Zak was efficient, knowledgeable and explained things in a way that I could understand. The walking boot he provided is much more comfortable and workable than the splint the ER put on. I feel confident in the care he provided and would recommend him.
Doctor explained everything well. He was very personable.
