Visit for more information on this month's participating artists. 

I welcome the public into my creative workspace once a month during the Cathedral Park Open Studios, where you have access to several artist studios throughout the building, including alternating vendors in the gallery. 

In my space you will find my remaining original numberism illustrations as well as my off series paintings and our full inventory of paper, canvas and screenprinted clothing. Everything is 10% off at our Open Studio and we have a rotating special promotion for you as well. You can also see whatever it is I'm working on at that time. 

Kid and dog friendly. Open to the public. You are welcome to park in the upper garage which will be open to you for the evening. You can also enter through the front doors. Follow the balloons and handy maps to find the studios you are looking for. 

August's Promotion: 

Free 8x10 paper print with any canvas purchase! 

The Building: 

We are at 6635 N Baltimore ave #264. The Main entrance is the garage! Come on in and go in the first double doors on your left which will bring you into the gallery where you will find maps like these to direct you around the building.
