So romantic and charming with a beautiful view of mountains. Iomosa has excellent customer service.
We had the best first impression with Jay at the Iomosa. He went above and beyond to accomodate our needs, and totally went out of his way for us more than once. He got to know us personally and really made us feel taken care of. This team makes all the planning stress free. If you are looking for a beautiful garden setting, this is the place to book. The Victorian beauty of the house is vintage and makes you feel like you are in a different time. You are guaranteed to have a picturesque wedding. The customer service is definitely run by the experts who have been doing weddings for a long time. I highly reccomend the historic Iomosa wedding and events.Sent on 03/12/2019

This is definitely one of the most personable venues I've ever encountered. The staff here work diligently and effectively to make every event totally tailored, totally personal, and 100% intimate no matter what the size is. The venue is stacked and stocked with top notch vendors (for glassware, tables, linens, etc) as well as a built in bar, canopy and anything else you might need. This is a historic house, so you can expect a historic feel. Lots of plants and a garden-esque feel bring this space a more intimate feeling and almost completely shut it off from the world outside it's doors and every event I've ever had the privilege of working at this location has been exceptional. I cannot wait to join the team in December for the Christmas celebration, and I certainly look forward to an incredible 2018 as this small team builds their reputation and their brand and continues to offer clients and couples the best service, the most comprehensive wedding and celebration packages, and a very personable and professional touch, simultaneously.
