Our Story

  < Started here Riverland Farm was located in Mequon,

just north of Milwaukee,

and an hour and half north of Chicago.  Riverland consisted of 38 acres of partly sloping former farm land, and lowlands that are bordered by  an oxbow (bend) of the Milwaukee River. The house , 10 stall barn, ( grown from a 7 stall barn), an indoor and outdoor Dressage arena, 3 and 4 rail fenced pastures with shelters, paddocks and round pen, sat on 12 acres with the rest groomed for trails full of wildflowers and wildlife.

We enjoyed our time there very much.

Regardless of the change in the name of our program to Kent Island Sporthorses, the following remains true:

With Donavan something wonderful is always happening!

With Rosall, there is always Excitement!

As of February, 2007,  Rosall was acquired  as our "Junior Stallion" , to bring  more wonderful talent, and variety to what we can offer North American breeders  and to match up with Donavan's lovely daughters!!

He will be trained and competed by Jessica Jo Tate!

Learn more about this excitement that Rosall is bringing to

the New Kent Island Sporthorses , and Team Tate Dressage.
