    He's a great doctor, listens carefully and explains every thing in language I can understand. I have total confidence in this doctor.
    *Dr. Kaskinsky is a excellent, knowledgeable physician (OBGYN) with superb manners.
    *Dr. Pkosinski came highly recommended to me, and I have (& will continue to) refer others to him & doctors in his office.
    I saw *Dr. K for a few years and then transferred to DC for 6 years. Upon my return I requested *Dr. K for my OBGYN.
    Great dr.!
