After working for 2 weeks - Pro's - Pretty good pay and health insurance. A few kind staff members. Con's - Very out dated office and software, poor management, management not willing to put in the effort to better the business. Owners will listen to recommendations and apply no changes. Very stuck in their old ways. Family owned and operated, literally everyone except one person in the business is related to each other, lazy employees who do whatever they want whenever they want, except for one employee, no business structure, no real training provided, dirty place to work. Not organized and always told no or I don't know to customers. Customer service from receptionist is lacking. No chain of command and owner and employees talk behind other staffs back.

I have been staying here since August of last year and so far it is the worst ever Jacob homes knows That my ground pipes are clogged due to the plumbers calling them and they have done absolutely nothing about it so I have had to buy gallons water for everything it's been a few months with out water We can't shower or use our toilet because our water is turned off because we have been waiting for repairs for months I would not recommend this place to anyone not even an animal the ground pipes are not our responsibility it's the owners responsibility to take care of and I hate to break it to ya but cps was called on me and they know about the plumbing so it's not my fault if the city gets involved excuse me but your blanton disrespect is exactly why people are moving out of your parks cuz you have no timely fashion and I am actually here legally due to owning a trailer here so the trailer I own was signed over to me and you will not come and take control of my property because i know my rights to my property and as a home owner I will burn my property before anyone who doesn't own it legally puts there hands on it try me

Critical: Professionalism, Punctuality, Quality, Responsiveness, Value I have been dealing with flooding for seven years now, and they have done absolutely nothing about it, and the sad part is Steve Jacob drove by just the other day and didn't even stop as I waved him down! Anyone know how to contact his boss?

Critical: Punctuality, Responsiveness Unprofessional, we are the customers, we shouldnt have to keep emailing for a response, they should respond back in a timely manner, they obviously don't want any business. We will go else where, thank you for your time sorry we were an inconvenience to you.
