“We are New York City office of a top-tier law firm in China actively involved in US-China cross-border transactions and other legal matters.  Over the last 8 years, Ruth and her team have represented us exclusively in various lease transactions.  During that time, she helped us relocate to Rockefeller Center and then expand two times within our building at 630 5th Avenue.  Most recently she assisted in expanding our premises to 7,000 rsf of beautiful, turnkey space.  Throughout the years, Ruth has been a steadfast advisor, always honest and thorough.  In particular, she provides us with excellent spreadsheets and financial analysis showing the total costs involved in transactions.  This is very helpful in accurately budgeting our real estate expenses.  I can wholeheartedly recommend Wharton Property Advisors to assist with any leasing matters.”

John Du, Esquire, Managing Partner, Jun He Law Offices

“I first met Ruth about 10 years ago when she helped me secure two NYC headquarters for tech firm Kenshoo at 14 Wall Street and then 80 Broad Street. Later, when I became COO of Fiverr, I engaged Ruth again to help us with our space needs. Over the years Ruth has advised me on numerous new leases and space expansions. Ruth has always been a steadfast advocate for our interests and helped me find and secure great office spaces. I can wholeheartedly recommend her services. She is honest, experienced and extremely savvy regarding all aspects of NYC office space.”

Vered Raviv- Schwartz, COO, FIVERR 

“We worked with Ruth in helping secure office space for one of our affiliated organizations, the Security Council Report. We were thrilled with the space that Ruth found – a very aggressively priced sublease in a top NYC office building, 885 Second Avenue, also known as One Dag Hammarskjold Plaza. Ruth has also assisted us with other transactions and she is always was extremely professional and knowledgeable about the office space market.”

Shari Colburn, Vice President for Real Estate, Columbia University

“Over the last 25 years Ruth has negotiated and secured nine (9) new office spaces on our behalf while also helping to dispose of various subleases over the same period. She has always found us excellent, below market deals in top NYC buildings.  Moreover, these spaces have usually included extensive trading infrastructure and supplemental AC systems, which is a terrific benefit for a hedge fund such as Clinton.  Specifically, Ruth has helped us lease approximately 200,000 rsf in: 405 Lexington Avenue, 30 Broad Street, 55 Water Street, 17 State Street, 9 West 57th Street, 601 Lexington Avenue and our current space at 510 Madison Avenue. She is extremely knowledgeable regarding all aspects of the NYC commercial real estate market and I highly recommend her to any firm looking for a lease / sublease in the New York area.”

John Hall, Chief Operating Officer, Clinton Group Inc.

“Since my firm’s inception in 1994 I have relocated my offices several times throughout NYC.  During that time I have used Ruth and her team as my exclusive real estate agent on every transaction.  Ruth has found us terrific deals on turnkey office spaces in major NYC buildings: 520 Madison Avenue, 1325 Avenue of the Americas and 152 West 57th Street.  The real estate business in NYC has many unscrupulous operators and agents.  Ruth is totally different and stands out in the crowd.   I always felt I was in good hands with her as she expertly navigated the twists and turns of our lease.  I thoroughly trust her judgment and have recommended her to several hedge fund colleagues who have also been very pleased.

Harvey Sawikin, Principal of FM, Firebird Management LLC

“I found Ruth thoughtful and creative about our office space situation, exceedingly knowledgeable about market conditions, pricing and sublet possibilities and scrupulously honest and straight with us. With significant effort, Ruth marketed a sublet on our half floor and found an appropriate non-legal subtenant. She guided us in pricing our space at 90 Park Avenue, and negotiated the essential elements of the sublease on our behalf. In addition, she obtained appropriate consents from our landlord and oversaw the implementation of the deal. After evaluating our use and needs she made several suggestions which saved us over $500,000.00 per year in rent expense.”

Daniel Ebenstein, Managing Partner, Amster, Rothstein & Ebenstein. 

“We have used Ruth and Wharton Properties as our exclusive real estate agents for over 10 years. She helped me relocate to 333 West 39th Street and then to Industry City. She has always been a steadfast advocate for us when negotiating with landlords and protected our interests regarding all our real estate costs. Most recently she helped us secure significant economic incentives from NYC on our relocation to Industry City”

Bill Marpet, CEO, B Live, Emmy award winner

“Empire State Realty Trust has worked with Ruth and her team on transactions throughout our portfolio, with a primary focus on the Empire State Building and One Grand Central Place. Ruth represents her clients with honesty and intelligence, while navigating the intricacies and complexities of the NYC office market.”

Ryan Kass, Senior Vice President, Empire State Realty Trust

“The Skin Cancer Foundation recently retained Wharton Properties to help relocate our headquarters to accommodate growth.  After an extensive search we settled on a full floor at 205 Lexington Avenue.  As a nonprofit, we had to be considerate of our resources and Ruth guided us through all aspects of the search, negotiation and relocation.  She was extremely helpful and professional at all times.  We are now in our new space and thrilled with the outcome”.

Dan Latore, Executive Director, The Skin Cancer Foundation

“We have used Ruth and Wharton Properties as our real estate advisors for over 15 years. She helped my firm relocate to 11 Penn Plaza, to sublease some extra space in that building and then to relocate again to 111 West 33rd Street. Ruth is a superb professional that really understands the changing real estate need of today’s businesses.  I was always delighted with the outcome and would without hesitation enthusiastically recommend Ruth to any NYC office tenants that need help with their space needs.”

Chesley Maddox-Dorsey, CEO, Access One Communications

“I have worked with Ruth as my exclusive agent for approximately 10 years. Ruth has been a terrific advisor in helping us secure our own leased space at 360 Lexington Avenue and then our current sub-leased premises at 250 Park Avenue. As President of a boutique investment banking firm, I needed to focus on my business at the same time as I was looking for appropriate office space. Ruth very quickly understood our needs, and only showed me suitable space, which was a very efficient use of my time. I completely trusted her judgement, and she successfully guided us through the many, moving parts of the leasing process.”

Oliver Cromwell, President, Bentley L.P.

“We are a mid-sized NYC law firm. Ruth has assisted us with our office leases for the last 20 years. Most recently, she helped our firm find and secure a terrific, 10,000 r.s.f. sublease at 230 Park Avenue. Not only was the space completely built, but all furniture and fixtures were in place for our use. Our office has sweeping views of Park Avenue and Ruth did a great job negotiating the economic terms of the sublease. We are delighted with all aspects of our new space.”
