Allison Ong Shreffler Architecture + Design LLC

5 Star Review by Marianne Twilley

We used Allison's services to update our 80s brick ranch by adding a porch, and the final product far exceeded our expectations. Her team was brilliant at incorporating the updates we had already done on our own and tailoring the design to our specific tastes. During the design process, they listened to our feedback and came back each time with adjustments. They were easy to work with from beginning to end. They gave us recommendations for quality contractors. They even helped us navigate zoning board issues we encountered. Highly recommend and will use again if we need design or architecture services! See before and after photos.

I have known Allison for more than a decade. Allison is knowledgeable, insightful, professional, organized and well-established in her field of architecture & design. She is super creative, her designs have been sought after. She has designed beautiful homes in Bergen County, NJ. I am always amazed on how creative and beautiful her creations are... makes you want to come home.

As a REALTOR® it can be a real challenge to find the right house in the right location for some buyers. I always tell them that the location cannot be changed, but the house can. Buyers love updated homes with fantastic curb appeal and unfortunately, that's not what is always up for sale - especially when you're looking in an area where homes are older. I don't hesitate to recommend Allison to my clients when they find a house they like but just want to make it more "theirs" or to add space. She has excellent architectural design & interior design skills that make it so easy to work with her on both the structure and the decor at the same time. Allison is a professional who communicates clearly and punctually with her clients. I highly recommend her!

As an outside trade rep for Pella Windows and Doors I rely on working with the best contractors and architects. Allison Ong-Shreffler & AOS Architect is, without a doubt, the best architect in the Harrisburg and surrounding areas. Allison's delightful personality and demeanor will set the tone to reassure you that you're, not only working with someone who knows their business but will also make sure you feel like you're opinion matters. Her attention to detail is incredible. Allison has a gift of being able to take people's ideas/dreams and turn them into a reality that surpasses what they originally expected. I have referred several Custom Home Contractors to Allison and they have all thanked me for it. If you are looking to build a custom dream home then AOS is the right architect for you!

Allison Ong Shreffler is one of the best in the architecture and design business! Central PA is fortunate to have such a talented person working in our area -- with both homeowners and businesses alike! Her reputation is well-known throughout the East and West Shore communities surrounding Harrisburg. Her work is incredible! My husband and I are working with Allison to remodel our kitchen. She has been great to communicate with and very understanding throughout the entire process. I'm excited to continue our relationship with her for future projects and ideas.
