    Mike has been successfully serving home buyers and sellers for over 25 years.  He knows not only the communities in the NRV but he is happy to share his knowledge.  Everyone needs to know the good, bad and the ugly when making what may become their largest lifetime financial decision.

    Mike and his wife live in Radford and have two boys that are attending Roanoke College and Virginia Tech.

    Mike’s business philosophy is simple, “You are the employer and I am the employee.”  If you value high ethical standards and enjoy humor, Mike is the REALTOR/employee you deserve.
