Dr. Hartman deserves more than 5 stars!! After living with severe shoulder pain for over a decade, I am now pain FREE after trusting Dr. Hartman with my surgery. After consultations with several orthopedic surgeons, I chose Dr. Hartman for his vast experience and amazing bedside manner. He made me feel so comfortable and confident every step of the way. I’m now two months out of surgery with no pain and I have Dr. Hartman to thank for this life changing experience! Not only is he a phenomenal doctor, but his office staff, PA, and physical therapy department is friendly, knowledgeable, attentive, and just overall top notch! I highly recommend you contact his office if you are in need of an orthopedic doctor, you’ll be so happy you did!

I visited Dr. Gregg P. Hartman for severe shoulder pain and was very impressed. He is both kind and knowledgeable; he not only treated my primary issue but also identified a congenital problem I’d lived with for years, teaching me more about my body in that half hour than any doctor had previously. The staff was equally fantastic—patient, and they clearly guided me through the entire visit, which I especially appreciated as I am hard of hearing. Highest recommendation possible. Five stars!

Dr. Hartman listened to me. The surgery was quick and his directions afterward were clear and concise. I felt totally at ease and experienced very little pain following surgery. I had a torn rotator cuff and bicep damage. Today, I am pain free and have 99% of a full range of motion.

I have been an athlete/in the fitness industry for 30+ years, and have had my share of injuries. I highly recommend Dr. Gregg Hartman @Ventura Ortho. He is extremely knowledgeable, honest and cares about his patients.

I have the utmost confidence in Dr Hartman…he is always very explanatory, gives undecided attention, and is always in a happy mood and willing to help.

Dr. Hartman was excellent. He diagnosed my problem quickly, and actually recommended surgery. The course of action fixed the problem within a month or two. I would highly recommend him.

Dr. Hartman is an awesome surgeon. He has performed surgeries on my shoulder and my knee. I closing in on 60yrs of age and with the success of these surgeries, It has allowed me to continue playing sports that I would not have otherwise. I highly recommend to Dr Hartman to anyone!
