I was nervous. I hate dental work, especially something like an extraction-but Dr. Waleed and his staff were great. I would go back without hesitation—but glad it’s all taken care of so I don’t need to.

An exemplary team of professionals. Dr. Waleed is a skillful and conscientious surgeon with a gift for conveying diagnostic information and articulating how the procedure addresses the specific need. I came away with a better understanding of the anatomy and genetic variables contributing to my condition and prognosis. Just as importantly, the procedure went smoothly, with a rapid and pain-free healing process, and I was very pleased with the outcome. The confidence and skill with which Dr. Waleed and his assistant Judy executed the procedure put me at ease, and his assistant Astrid was also very kind and professional on my follow-up visits. Desirae and Sharon were graciously responsive with scheduling, providing supplemental information, and communicating with my insurance company and pharmacy. I could not have had a better experience!

I highly recommend Dr. Waleed Alkakhan, he has been my doctor for two years, and he provides outstanding care for all patients. He informed me in detail about everything that was going on, and I left the building satisfied. The office is very clean, and the staff is very kind. If you are thinking about going there, I highly recommend you do so.

Dr Waleed performed our sons procedure and his work, follow up and the practice as a whole are truly world class. We would recommend them with no reservations especially to families and younger patients.
