Patients Love us on Yelp

"I conveniently made an appointment over the phone but they accept walk-ins as well. Upon visiting the clinic, I was greeted and checked in promptly. I had more than a few things I needed to check/do and was taken care of in under an hour. Friendly and professional staff as well as physicians. Will recommend to others."

"TotalCare staff are genuine and respectful. They go above and beyond in providing personalized care. Today is my last visit before moving out of state and made sure that my medicines would have refills available after my move. Thank you TotalCare!"

"Great staff!  Excellent care and professional attitude!  Answered all questions and was very thorough with answers!"

"My first experience with total health was great.  Checked in quickly, Molly the PA examined me and provided my options to get better.  Not rushed, and very professional.  My prescriptions were sent electronically,  which saves time compared to handwritten scripts.

Glad to have a new go-to urgent care in Corona."

"Thank you TotalCare for making my phone call appointment so easy! Feeling sick with fever and all that congestion is hard to deal with, I really appreciate the patience of my doctor! She asked all the right questions to get my symptoms and figured out just want medicine was best for me."

"Dr. Zhang has been my primary doctor for many years.  She strives for excellence at the clinic and will accept nothing less.  I always give a good reference if anyone is asking. The office staff is courteous and helpful and answers any questions you may have.."

"I love this place! I've been coming here for almost three years now. I never have to wait long and I'm always treated with respect by all of the staff. If I need blood work or I'm sick they take me in right away. I would highly recommend Dr Wang as your primary Doctor!"

"Dr. Wang is the best Primary care provider I've ever had. He is very detailed and listens to his patients thoroughly. His office is open late and the wait is not bad at all. You can come in here for anything from Bronchitis to a complete physical."

"It's great to be able to walk in and be seen by a great doctor. I like their extended hours too. Everyone is really welcoming and friendly."

"Great Urgent Care. Nice staff and very attentive. I had laringitis and needed to be ready for an interview that I had in two days.  Dr. Wang gave me options and addressed my situation in a professional way. Feeling better as Dr. Wang promised."

"Hi, my wife & I started coming to total-walkin clinic couple of years ago, we are pleased with the staff, helpful, friendly. HCG diet!!! Let me just say! I was weighing in at 315lbs 3/17. I lost  3/4lb of fat not muscle a day for 40 days! With a new diet change in my eating habits, I'm eating healthy now, I've continued to drop weight feeling good at 225lbs 11/29/17. Dr Wang thank you! Also!!! HCG helped me reverse diabetes!"

"Dr. Wang and staff are always so kind and helpful. I appreciate the fact that we're never waiting long to see the doctor AND the fact that the doctor takes his time to address all our issues and answer all of our questions. I never feel rushed. The office is always clean and also open 7 days a week, which makes it very convenient for visits."

"This is a second location for Dr Wang. He is a wonderful Doctor. The thing I like about this Dr is that he spends time with the patients and not rush them. He is very sympathetic and caring to all his patients. He has been my primary for over 10 years. Even though it takes me 40 minutes to get to Eastvale location it's worth the drive."
