Patient Comments (6)
Simi Valley, CA |
I moved to Simi Valley from Santa Clarita and was trying to find a new Gastro Dr. I tried a few others out here that are part of my PPO, but none were as knowledgeable and understanding as Dr. Weise. She is a great doctor. She has patience and gives you the time you need when you visit. Most importantly you barely wait at all for your appointment (the previous doctors I have seen made me wait over an hour for my appointment and then more time waiting to see the doctor!). Great staff, too!

Love her! I am a healthcare provider and I think she is knowledgeable and kind!

I came to her when with horrible stomach pains from Small Intestinal Bacterial Overgrowth and Candida Overgrowth and awful constipation and was wasting away from not being able to eat anything due to food intolerances caused by Leaky Gut and all she did was give me probiotics and tell me to come back in two months. She never heard me out, or gave me the time of day. Not kind or compassionate at all. Just one of those doctors who has you in and out as fast as possible.

One of the best doctors I've ever had! She is very patient, friendly, knowledgeable, and caring. Why can't all doctors be like Dr. Wiese?!
Newbury Park, CA |
I have complete trust in Dr. Wiese, who I found to be wonderful in knowledge and manner. Her staff is also very friendly and courteous. However, the staff is lacking in other areas, including follow up to phone calls regarding test scheduling and test results. I recommend making it a point to call them regularly to make sure such things are done in a timely manner.

Excellent listener. VERY personable and great bedside manner. Good at calming fears and providing information. Doesn't talk down to patient. Errs on the side of caution with tests with the caveat to the patient that it is most likely something benign.
