Dallin Davies is very impressive. He followed me through weeks in the hospital after a head on collision and was extremely through even during my follow up in the office over a month later. He's very knowledgeable and patient friendly. I'd choose him any day and highly recommend!

My appointment with Dallin Davies went really well. He was very thorough in explaining my lab report and then extracting my body piercings, Staples.

I am thankful I landed in the care of Dr. Van Essen. First, he worked with his team to schedule my surgery as soon as possible. Second, he was thorough in regard to my condition and what to expect after surgery. Third, he personally contacted my husband via phone several times before and after surgery as my husband was unable to be with me during my hospital stay. Wow! Fourth, Chelsea, his nurse scheduled blood work and was quick to answer my questions and/or forward concerns to the doctor. I so appreciate such kind and expert care. Thank you.

Both Dr Shiao and Dr Davies have been kind, understanding, very professional and honest during and after a very uncomfortable and embarrassing procedure. This includes all of the nursing staff as well. I highly recommend

I had a significant dirt bike crash that resulted in a perforated bowel. Dr. Sekharan performed my surgery and she did a wonderful job. Not only did she fix the problem, but she also left me with the smallest incision she could. That truly means a lot to me. PA Christensen completed my follow up appt and removed my staples. He answered all our questions and ensured everything was healing well. It was not a fun situation to be in, but I'm thrilled we have such talented and qualified physicians in our area. Highly recommend.

Overall I had a very good experience with this provider. Dr. Welsh took a lot of time explaining my procedure before the surgery, exactly what was done, and what I could expect in terms of my recovery. Dr. Welsh seems very experienced and extremely proficient in all aspects of robotic laparoscopic surgery. I am confident in his work and I expect a full recovery. I highly recommend him and the General Surgeons of Western Colorado staff.

Being diagnosed with breast cancer and having to see a surgeon was so overwhelming. Walking into the office, it was bright, clean and welcoming. My husband and I were greeted by the receptionist she was very pleasant and friendly. The nurse taking the vitals was super nice and had a wonderful sense of humor. Jade is a wonderful PA, she is very engaging and knowledgeable.

She spent time answering all of our questions. She is a great addition to Dr. Sekharan's team Dr. Sekharan is fantastic She sat right across from me, made eye contact with us both while explaining the up coming procedures and going over details. She has such a wonderful demeanor and put us both so much more at ease. This office gets a A++++ I would 100% recommend them to my family, friends, too anyone.

Dr. Andersen is wonderful! He made me feel very comfortable and was very patient and informative with my questions. Health issues can be so scary and stressful and he seems quite compassionate to that fact. I have yet to have my surgery but feel very confident I will be in great and competent hands. The office staff is very professional and friendly too.
