Excellent!
Staff are courteous and considerate, all of them that I've had the pleasure of dealing with. Information shared related to my specific issues were/are addressed with my best health care options offerred.
Covered all the important areas! Dr Lee- Allen thought thoroughly through all my past history... Ordered new tests... We are in the process of finding out why I am having the problems I have. She was kind, caring and too the point. One of the best and smartest doctors I've seen. The staff also was attentive and kind. The facility was clean and comfortable.
This is a solid and reliable medical practice. Every provider we have seen has been thoughtful, smart, compassionate, and willing to spend time to understand and help. Five stars.
Staff were very knowledgeable and caring of my needs. Highly recommend.
I trust Johnathan with my life literally. I have been with this group for over 25 years Chrones IBS etc. A few months back hospitalized for 13 days after a very long remission. Every day one of the GI drs were there to see me.They continued daily to assess and answer all my concerns.I will continue to see Jonathan as needed as he is by far one of the most compassionate educated of any GI I've worked with on remaining healthy 😀
Each person I had contact with was friendly and helpful. From the receptionist to the nurse to the DR herself!! If you have digestive problems,this is the place to come!!!
I have used your facility several times. I have always found it to be extremely clean the staff is very thorough considerate and knowledgeable. They answered any questions I asked them they were very caring and concerned and respectful of me they were quick at what they did they knew what they were doing. This will be the only facility I ever use. Great job guys I appreciate your kindness and your professionalism
