I am in Oregon and needed a document served to a difficult to reach client and Mark connected me with one of his resources in his network! I’m talking quickly and efficiently! I can’t recommend him enough! Excellent service! My project was handled and completed within 24 hours of him introducing me to the agent! 🙌🏽🙏🏽
