Rating & Reviews
Wonderful team! Provider was very thorough!
Everyone was nice and understanding
The doctor worked hard to answer any questions, provided a plan for moving forward, and asked background information. She also connected with my child and was friendly.
Dr. Collyer and her staff were very kind, attentive, knowledgeable and professional. Dr. Collyer treated me and my son with the upmost respect and grace. I greatly appreciate her listening to my concerns, validating my feelings and ordering tests to further investigate what is going on. I look forward to continuing to work with her and her staff. She was also thorough providing short term and long term goals & interventions.
I appreciate that Dr Collyer took the time to listen to my concerns and wasn't in a hurry to run out the door.
The doctor was excellent on every way,
Dr. Collyer was awesome! She was so kind, friendly, patient, caring, and explained things to me that I could easily understand. She gave me opportunity to ask as many questions that I had at the time, and I appreciate that! This is our initial visit with her, and I'm glad we have her as a doctor! :)
The doctor was very thorough and addressed all of my concerns. She truly listened. This great experience made me wonder if my son's previous doctors ever went to medical school.
Dr Collyer is amazing! We are blessed to have her on our team!
I only trust PCH specialist with my sons care. Despite the rare genetic disorder he has specialist do all they can for him. GI department is amazing always so professional, patient, respectful, give positive vibes. I am so happy GI Doctor Collyer is taking care of my son. Since day one she has and continues to do what is best for my son provides great recommendations and always address any and all my concerns. Thank you for all you do .
This doctor was absolutely amazing. I switched GI's cause I felt the last one did not listen to my concerns or take into consideration that my son is severely autistic. But I mentioned that to this doctor & she heard me. And she listened to me about how I did not want to do anymore invasive treatments until we have an understanding. I really liked her. She was sweet to my son & listened to me. That's all I can ask for.
The Dr was very nice an tranparent. Got to business with my needs.
Dr. Collyer is amazing, and I would recommend her without hesitation to anyone.
Excellent experience as my daughter is a new patient to Dr. Collyer. Her and the and the other provider working with her were so informative and thorough. Great care and very comfortable. My daughter really liked her. Thank you.
I absolutely love Dr. Collyer and the entire GI staff. From the front office to the nursing staff, everyone was professional and courteous. My daughter, who has doctor related anxiety, was completely at ease and smiling as she left the office. Thank you for always being an amazing provider. We truly appreciate you.
Dr. Collyer is an amazing, understanding doctor! Highly recommend!
Elizabeth is very helpful, polite, and knowledgeable and recognizes the importance of my child's health
