I started seen Doctor Gregorius in 2017 and I had two surgeries with him. A left hip and left shoulder. The pain from each surgery has been minimal and healing time amazing. This only happens when you have excellent care from your doctor. I can’t say enough about Dr Gregorius. Thank you for the help, service and the continuous follow up.

Absolutely one of the best surgeons around. I drive 70 miles for his expertise.. family and friends use him for all ortho needs..

Dr. Gregorius is a thoughtful, caring doctor who takes the time to understand you as a patient and find the best course of treatment for your lifestyle. His surgical skills are amazing. He shows integrity in describing the possible recovery outcome so that you are fully informed and carefully outlines all your options without pushing surgery. His follow up care is amazing, he never cuts time short and he always knows whats going on.

Dr. Gregorius is awesome. He is detail oriented and truly cares about his patients, which is what you want in an orthopaedic surgeon. His assistant Yume is awesome, if you need anything she is very responsive. His surgery scheduler, Jasmine is easy and great to work with as well. Thank you so much for helping me with my Knee surgery. I would hands down recommend him. Thank you to all of you at California Orthopaedic Specialists.

Dr. Gregorius was the “On Call” doctor over the weekend covering my elderly mother’s orthopedic surgeon. He took care of her urgent situation as if we were his own patient. So personable and willing to help us. I can’t thank him enough. My dad’s name is also Theodor but without the e at the end. Great doctor with a great name!! Thank you Dr. Gregorius. 👍🏻

Hands down the best surgeon around. I’ve been to several orthopaedic doctors and from the start I knew Dr. Gregorius was confident is his diagnosis and his work is amazing. He’s fixed my knee and now my shoulder. I can’t thank him enough. Aside from his gifts as a surgeon he’s a solid citizen & someone I admire greatly. Get to know him!

Amazing. This guy has given me my life back. A true gentlemen and a class act surgeon. I would recommend this guy hands down to anybody that has any serious orthopedic problem. He truly cares about his patients at all points in the patient relationship (before, during and after the surgery room). This is the kind of guy that instills total confidence in you as to his caliber of performance. Although the need for this kind of doctor requires extreme injuries, Im looking forward to the opportunity and honor of referring him his next patient. I know they will be in the care of the steadiest of hands, the sharpest of minds and the care and compassion of the kindest of heart.

Dr. G has worked on my shoulders and knee and everyone was a success.. get bed side manners.. a doctor that truly cares.

Dr Gregorius has done surgery on my brother twice he is highly trained in his field and a fantastic surgeon. He is very accessible and cares truly about his patients care and well being. Highly recommend him as a surgeon who specializes in Sports Medicine

Dr. Gregorius is AWESOME! He is the best doctor. He is so kind, caring and good at what he does. He helped me so much. I truly appreciate having such a great doctor to help me.

I was so lucky to have Dr. Theodore Gregorius as my orthopedic doctor in Newport Beach, CA. Shoulder surgery was my last resort but he was patient to answer all of my questions, and to make sure I understood what was going on to make me feel comfortable. If needed I would definitely go back to him again.

Dr. Theodore Gregorious is the Real Deal. Ive had 3 other surgeries at another local Orthopaedic facility which left a rather sour taste in my mouth, I was referred here by my friend, and Doctor. I got my MRI, appointment and surgery in less than 2 weeks. He was very detailed in what was wrong and actually took his time explaining to me what his procedure and expected outcome would be. All this was done and produced a very comfortable sense of ease. I strongly recommend him for anyone whos ready to take the step to get their joint problem fixed and back to normal. Make sure to look up his resume as well... He has numerous accomplishments and and very respectable affiliations from some of The countrys biggest colleges to professional sports teams as well.

Doc G. will forever be the BEST OF THE BEST! He performed three surgeries on me. He healed my well torn up right shoulder. More significantly, he was savior of a “totally shattered” left ankle, after my having had it literally collapse beneath me during a roller skating fall. Needing an imminent surgery, and although Doc G. was off and enjoying his vacation/family time, I was was told that one of his colleagues would be doing the surgery (&my anxiety went bursting to the sky!). Then I was told that I couldn’t have the procedure done due to “insurance issues/approval”, and was going to need to reschedule...Ummmm... NOPE!!! It quickly all was turned upside down, and instead it was Doc G. to my rescue:)Imagine, a orthopedic surgeon taking off from his time off work,& in the middle of spending time with family in New Port, CA to hit the gas pedal up to 100mph!!! Heading straight to St. Bernadine’s Medical Cntr. in SanBernadino.SERIOUSLY,...CAN YOU EVEN IMAGINE THAT??!?Well, that’s the honest to God truth. He swooped in like Super Man! Lol! Personally escorted me to registration, through registration,& ran me in my wheelchair down the long hall that led straight to the “pre-op” location. The nurses ALL looked shocked (because it’s just unheard of for a physician to bring / transport a patient into the “pre-op” area). BUT, Doc G. is not just your average doctor, or rathe a orthopedic physician!!! NOT BY THE FURTHEST THROW OF ANY KIND!! He is a one of a kind. He is the best,& if anyone begs to differ ... Well, let’s just say... Let’s take it outside for discussion. Jk!DOC G. IS AN AMAZING MAN, PERSON, EMPLOYER, HUSBAND, FATHER, SON, ORTHO-PHYSICIAN, AND WITHOUT A DOUBT HE IS ONE AMAZING FRIEND!I was more that *Lucki to have found him...I believe in my heart that I was blessed.Thank you to the Moon and Back, Doctor Theodore Gregorius.Always&Truest,*Ms. LUCKi S.*

Very lousy practice and doctor to return calls. He placed me on disability and said wanted to see me the following week for follow up. Then I left several messages and emailed his assistant but no one returns calls to schedule an appointment. This has been my experience with him and his office all along. Very lousy care. When you finally get to see him he rushes you out and doesnt examine you. I have never claimed a 10/10 pain in my life until last week in his office when I was in agony and crying. He didnt exmaine my knee. I asked him to please examnie my knee and that is when he found the multiple findings.Also, he forgets your diagnosis, he forgets that he is the priamry treating phyisican , he is ready to butcher you and he tells you not to follow up if you dont wants surgery. I am a nurse practitioner and surgery is my specialty. I deal with orthopedic surgeons on a daily basis. Never think that newport beach gives you a 5star physician. Wrong. I would have never let him operate on me anyways. I ended up with him because workers comp gives you a list and you have to pick one and I am glad i got to know before he cut me open.I guarantee you will regret your visits with him. I also found out in my last visit that he is changing group, God knows for what.

Was treated as a individual and not a number. He cares about your outcome. Wouldnt have anyone else fix me.

Excellent surgeon , excellent follow up care.

Get a second opinion before you do anything this doctor suggests.

Dr. Gregorius, on January 3, 2018, gave me a surgery on my right shoulder. I am very grateful because I have felt very good that I recovered almost all my mobility.
