Dr. Waleed has been treating me for several years and placed my implants. I’ve had an amazing experience from his front desk staff, assistants, and painless treatment! Highly recommend Dr. Waleed and his practice!

Dr Carpio and Dr Alkakhan run a wonderful practice. I've had two procedures at their office, one with each doctor, and I felt nurtured, cared about, safe, listened to, and seen. The entire office, from reception to assistants to the doctors, are kind and calming. I was apprehensive about sedation and the whole thing, and I was wowed at how easy and at ease they made me feel. Highly recommend for anyone needing gum related procedures.

My initial consultation with Dr. Alkakhan was excellent. He is very thorough in his examination and answering my questions. His thoughtful approach is appreciated as well in not rushing to conclusions that required further consideration on his end together with consulting with my primary dentist. The staff is also very friendly from the front desk to the dental assistants/technicians.

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.
