I am a medical professional myself and understand exactly what it means being in this medical field. I have worked with and for other doctors but I've never met a doctor as thorough and competent as Dr. Osia Sisom. He listens to you and treats you holistically. He does not rush with the 8-minute rule for doctor/patient contact. Dr. Osia will pull his chair, sit down with you and allow you maximum time to explain your issues. He not only gives you referrals, he calls the specialist he is referring you to and makes the appointment with you. His referrals are to top-notched specialists who have the same work ethic as Dr. Sisom. His wait hours may be long, but they are worth the wait. Would you not rather wait for a doctor whom you know will listen, pay attention and make sure you and your loved ones are truly taken care of? He is awesome and all my friends and families I have referred to him have all come back to thank me.

This doctor seems more about getting money than caring about your health. Instead of taking the correct tests, he just went and prescribed me a bunch of prescription drugs.

The office staff are very unprofessional. Very young women that could care less about customer service. I have can't get any call backs even from the office manager regarding care, records, referrals. Dr. Osia on the other had was wonderful, should choose as staff that compliments that.
