I am so pleased with Terra Vista management company. I have been volunteering with my HOA for a few years now and Terra Vista has been reliable when everything is going well- but also dedicated when questions and issues come up at our complex meetings and are quick in getting them resolved- a great local company!

 I can’t thank them enough!
 Thank you, 

Irene Allen

I have been a home owner at Pacific Sands complex in Marina CA since more than a year ago. Within this time, I have been dealing with the Terra Vista HOA Association on a regular basis and I have found them to be incredibly helpful, genuine in their assistance to the homeowners and in some cases, have gone over and beyond their means to accomplish a task for the homeowners.

I have specifically worked with Andrea before and most recently with Ariel and they have been very prompt with their responses and diligent in accomplishing tasks. They have certainly exceeded my expectations.

I am very grateful and hope that such professional relationship continues in the future.
